DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0055] The illustration in the drawing is schematically.

[0056] Before describing further exemplary embodiments in further detail, some basic considerations of the present invention will be summarized based on which exemplary embodiments have been developed.

[0057] More and more motors in a car are converted to the so called brushless DC (direct current) topology. This topology simplifies the motor construction but increases the electronic control effort. This effort however also pays off in form of improved motor precision and efficiency. In such automotive applications, packages with half bridge functionality are implemented. Also in other applications, for instance domestic appliances such as washing machines and dishwashers, such kind of packages may be used.

[0058] A conventional challenge is to find a cost and space efficient solution for half bridge transistors (such as MOSFETs) for the above and other electronic applications.

[0059] According to an exemplary embodiment, a clip design for a half bridge package is provided which combines a compact design with a higher electric reliability and a simple manufacturability. In an embodiment, a clip design is provided which realizes a half bridge configuration implementing a three-connection-sections-clip. More specifically, such an embodiment provides a special clip design to build up electrical connections between chip terminals and chip carrier terminals which may be at different height levels. An advantage of such embodiments is simplicity. A simple and cost efficient leadframe design may be used for providing a corresponding chip carrier. A half-bridge interconnection may be realized by a specific clip design introducing three connection sections, in particular at multiple (more particularly three) different levels. FIG. 1, which will be described below in further detail, shows an embodiment in HSOF package outline configuration. However, other embodiments of the package architecture can be implemented with very different types of packages, such as DSO (see FIG. 3 and FIG. 5), etc. Apart from this, also a PCB (printed circuit board) design may be simplified by such and other embodiments, in particular for motor applications.

[0060] A gist of an exemplary embodiment is the use of a package with splitted leadframe with pin configuration and the use of a specific clip design to build up a half-bridge configuration in one package. Specific for the clip is a sophisticated electrically conductive connection configuration between a chip surface, a connection lead and a leadframe body.

[0061] In the following description of exemplary embodiments referring to the figures, field effect transistors are implemented as first chip 104 and second chip 106. These chips 104, 106 with field effect transistors will be denoted in the following simply as chips 104, 106. However, it will be understood by a skilled person that all embodiments described in the following can also be implemented with other transistor types (such as an insulated gate bipolar transistor). In other words, the mentioned chips 104, 106 can also be realized as chips of different technology.

[0062] Correspondingly, first connection terminals 130, 140 will be denoted in the following as source terminals 130, 140, and second connection terminals 132, 142 will be denoted as drain terminals 132, 142. Accordingly, control terminals 134, 144 will be denoted in the following as gate terminals 134, 144, although they can be configured as other types of control terminals, such as base terminals.

[0063] FIG. 1 show a plan view of a package 100 according to an exemplary embodiment. FIG. 2 show a cross-sectional view of part of the package 100 according to FIG. 1.

[0064] Referring now to FIG. 1 in detail, package 100 is shown which comprises an electrically conductive chip carrier 102, which may for instance be completely or exclusively electrically conductive and which is here embodied as a leadframe consisting of copper. As an alternative to copper, also iron can be used as a material for the leadframe-type chip carrier 102.

[0065] A first chip 104 with an integrated field effect transistor (more specifically a MOSFET, i.e. metal oxide semiconductor field effect transistor) is mounted on the chip carrier 102 and comprises on an upper side a source terminal 130, on a lower side a drain terminal 132 located (for instance soldered directly) on the chip carrier 102 and on the upper side a gate terminal 134. A separate second chip 106 with an integrated field effect transistor (here also embodied as a MOSFET) is also mounted on the chip carrier 102 and comprises on an upper side a source terminal 140, on an lower side a drain terminal 142 located on the chip carrier 102 and on the upper side a gate terminal 144. As can be taken from FIG. 1, the first chip 104 and the second chip 106 are arranged on two separate islands or leadframe bodies 188, 192 of the chip carrier 102. More specifically, the leadframe-type chip carrier 102 according to FIG. 1 and FIG. 2 comprises the two leadframe bodies 188, 192 and additionally multiple separate connection leads 186. The islands or leadframe bodies 188, 192 are mutually electrically isolated from one another, and are only connected with one another and with the connection leads 186 by clips 170, 190 and bond wires 191, 193.

[0066] The first chip 104 and the second chip 106 are electrically interconnected with one another to form a half bridge circuit (see also FIG. 4). In terms of this half bridge arrangement, the first chip 104 is configured as a low-side switch and the second chip 106 is configured as a high-side switch.

[0067] Both the first chip 104 and the second chip 106 are configured for operation with a vertical current flow, i.e. with a current propagation direction perpendicular to the paper plane of FIG. 1. Both the drain terminal 132 of the first chip 104 and the drain terminal 142 of the second chip 106 are electrically connected to (for instance are soldered directly on) the chip carrier 102, more specifically to the respective leadframe body 188, 192. The drain terminals 132, 142 which correspond to a lower main surface of the chips 104, 106 are hence electrically conductively mounted (in particularly electrically conductively glued, soldered or sintered) directly on an upper main surface of the chip carrier 102 (i.e. without any further connection element such as a bond wire, etc. in between). In contrast to this, the source terminal 130 of the first chip 104, the gate terminal 134 of the first chip 104, the source terminal 140 of the second chip 106, and the gate terminal 144 of the second chip 106 are arranged on an upper main surface of the respective chip 104, 106 and are electrically connected to the chip carrier 102 via the clips 170, 190 as well as the bond wires 191, 193. The gate terminals 134, 144 are thus arranged facing away from the mounting surface of the chip carrier 102. Also the two source terminals 130, 140 are arranged facing away from the chip carrier 102. In contrast to this, the two drain terminals 132, 142 are arranged facing the chip carrier 102. Via the electric connection elements in form of the clips 170, 190 and the bond wires 191, 193, the vertical gaps between the plane of the terminals 130, 134, 140, 144 on the one hand and the upper main surface portions of the chip carrier 102 are bridged (see also FIG. 2). Thus, each of the electric connection elements in form of the clips 170, 190 and the bond wires 191, 193 is configured to electrically connect a respective one of terminals 130, 134, 140, 144 at a top side of one the chips 104, 106 with the chip carrier 102. In other words, the source terminals 130, 140 and the gate terminals 134, 144 are located on a surface of the chips 104, 106 facing away from the chip carrier 102 and the drain terminals 132, 142. The latter are located on a surface of the chips 104, 106 facing the chip carrier 102. In particular, the drain terminal 132 of the first chip 104 and the source terminal 140 of the second chip 106 are located on different height levels of the package 100 (see H1, H3 in FIG. 2).

[0068] An encapsulant 112, in particular a mold compound, is provided for encapsulating part of the chip carrier 102, the entire first chip 104 and the entire second chip 106. In other embodiments, it is also possible to omit encapsulation or molding.

[0069] As a result of the coupling architecture described in the following in further detail, the first chip 104 and the second chip 106 are connected to form a half bridge having inlet terminals 178, 180 and an outlet terminal 182. Reference is also made to the circuit diagram corresponding to a half bridge configuration shown in FIG. 4.

[0070] The clip 170 has three connection sections 172, 174, 176, i.e. three electric clip terminals at which an electric coupling with another electrically conductive portion of the package 100 is established via the clip 170. These connection sections 172, 174, 176 connect the drain terminal 132 of the first chip 104 with the source terminal 140 of the second chip 106 and with the outlet terminal 182 of the half bridge. More specifically, the three connection sections 172, 174, 176 are in contact with and electrically connect an upper surface of the second chip 106, two of the connection leads 186 corresponding to outlet terminal 182 and the leadframe body 192 on which the first chip 104 is mounted. As can be taken from FIG. 2, the connection surfaces of the three connection sections 172, 174, 176 of the clip 170 are located at three different height levels H1, H2 and H3. More specifically, the three connection sections 172, 174, 176 of the clip 170 comprise a curved plate portion (see reference numerals 172, 174) and a web portion (see reference numeral 176) extending substantially perpendicular from the curved plate portion (see reference numerals 172, 174). The curved plate portion (see reference numerals 172, 174) comprises two planar subportions at different height levels H1, H2 connected by a slanted intermediate subportion 184. The web portion (see reference numeral 176) extends up to a lowermost height level H3 of the clip 170. In a viewing direction along an extension of the web portion (see reference numeral 176) from the bent or curved plate section (see reference numerals 172, 174) up to a free connection end of the web portion, i.e. in a viewing direction perpendicular to the paper plane according to FIG. 1 or along a vertical direction of FIG. 2, the slanted intermediate subportion 184 connects the two planar subportions (see reference numerals 172, 174) being laterally displaced relative to one another. Beyond this, the curved plate portion (see reference numerals 172, 174) is attached to the connection lead 186 of the chip carrier 102 (compare reference numeral 174) and is attached to the source terminal 140 of the second chip 106 (compare reference numeral 172). The web portion 176 however is attached to the leadframe body 192 of the chip carrier 102 on which the first chip 104 is mounted (compare FIG. 1 and FIG. 2).

[0071] Again referring to FIG. 1, the package 100 comprises the further clip 190 connecting the source terminal 130 of the first chip 104 with corresponding connection leads 186 of the chip carrier 102 which are at an electric ground potential.

[0072] According to the embodiment of FIG. 1 and FIG. 2, the first chip 104 and the second chip 106 have the same shape and dimension. The advantage is simplicity, since only a single type of chips is sufficient for providing the entire transistor functionality of the half bridge.

[0073] Thus, the embodiment according to FIG. 1 and FIG. 2 provides the clip 170 with a design implementing a landing at three different points (see reference numerals 172, 174, 176) and height levels (see reference numerals H1, H2 and H3). Connection section 174 corresponding to height H2 represents the highest connection point of clip 170. Connection section 172 corresponding to height H1 represents a middle point. Connection section 176 corresponding to height H3 relates to the lowest connection point of the clip 170. The electrically conductive portion between connection terminal 172 corresponding to height H1 up to connection terminal 174 corresponding to height H2 provides for an electrical connection of the source terminal 140 of the second chip 106 (and connects, more precisely, an upper chip surface of the second chip 106 with a connection lead 186 of the chip carrier 102 corresponding to the outlet terminal 182). The electrically conductive portion between connection terminal 172 corresponding to height H1, connection terminal 174 corresponding to height H2 and connection terminal 176 corresponding to height H3 makes an electrical conductive connection between the source terminal 140 of the second chip 106 and to the drain terminal 132 of the first chip 104 to form a half-bridge configuration with out-pin or outlet terminal 182.

[0074] According to the design of FIG. 1 and FIG. 2, all connection leads 186 are located on one side of the package 100. Alternatively, connection leads 186 of a package 100 may also be located on two (in particular opposing) sides of a package 100 (as in FIG. 3), or on all four sides of a package 100 (as in FIG. 5).

[0075] In order to mount a respective chip 104, 106 on a respective leadframe body 192, 188, it is sufficient to simply place the respective chip 104, 106 on the respective leadframe body 192, 188 with a solder paste (for instance based on tin, for example having a thickness of 60 m) in between in a solder oven. Due to the influence of the force of gravity of the respective chip 104, 106 in combination with the surface tension of the solder, the respective chip 104, 106 will be soldered accurately on the respective leadframe body 192, 188. This soldering procedure may be carried out efficiently on batch level, i.e. before singularization of the individual packages 100.

[0076] Advantageously, cumbersome source-down or flip-chip configurations may be omitted in the embodiment according to FIG. 1 and FIG. 2. This renders the manufacturing process simple since there is no necessity to involve a large number of masks and due a long manufacturing process (as occurs with flip-chip technology).

[0077] FIG. 3 show a cross-sectional view of a package 100 according to another exemplary embodiment in DSO splitted leadframe configuration. FIG. 4 shows a circuit diagram of the package 100 according to FIG. 3. In the package configuration according to FIG. 3 and FIG. 4, a control chip 200 is shown which is connected to the gate terminal 134 of the first chip 104 and to the gate terminal 144 of the second chip 106 for controlling operation of the first chip 104 and the second chip 106. As can be taken from FIG. 3, the control chip 200 is mounted on top of the second chip 106. Hence, FIG. 3 shows a half bridge with a chip-on-chip architecture what concerns chips 106, 200.

[0078] In order to properly adapt the functionality of the package 100 to different duty cycles of chips 104, 106, the embodiment of FIG. 3 shows chips 104, 106 have different shape and dimension.

[0079] Various electric potentials IN.sub.X, V.sub.S.sub._.sub.IC, V.sub.s, GND are indicated in FIG. 3 and FIG. 4. Moreover, the three different height levels H1, H2 and H3 of clip 170 are indicated in FIG. 3.

[0080] FIG. 5 show a plan view of a package 100 according to yet another exemplary embodiment.

[0081] The embodiment according to FIG. 5 differs from the embodiment according to FIG. 3 in that, according to FIG. 5, the control chip 200 is mounted on a separate further (i.e. third) leadframe body 194 of the chip carrier 102. Thus, FIG. 5 shows a half bridge with a chip-by-chip architecture what concerns chips 104, 106, 200 being arranged side by side. The package 100 according to FIG. 5 is embodied in a Quad leadframe configuration, i.e. having connection leads 186 on all four sides of the package 100.

[0082] Although an encapsulant 112 may also be present in the embodiments of FIG. 3 and FIG. 5, such an encapsulant 112 is not shown in these figures.

[0083] FIG. 6 shows a circuit diagram of an electronic device 150 configured as a three phase motor bridge comprising multiple packages 100 according to an exemplary embodiment. FIG. 6 shows a circuit of a three phase motor control.

[0084] For each phase of a motor 212, a package 100 with half bridge MOS configuration, composed of a high-side MOS (see reference numeral 106) between a supply voltage and phase and a low-side MOS (see reference numeral 104) between phase and ground, is implemented. FIG. 6 hence shows a configuration of a three phase motor bridge with three high-side MOSFET chips connected to a battery and three low-side MOSFET chips connected to ground.

[0085] According to FIG. 6, a supply voltage (here +12 V) may be supplied from a battery to the various half bridges realized in form of the three packages 100. The packages 100 may for instance be embodied as shown in FIG. 1 to FIG. 5. Control chip 200 (which may also be denoted as driver chip) is foreseen which can receive a pulse width modulation (PMW) signal via a connection 202 from a microcontroller 204. The microcontroller 204 may receive a diagnosis signal, via connection 206, from the control chip 200. Moreover, one or more supply chips 208 may be provided, as well as a transceiver 210 (for instance embodied in accordance with CAN/LIN communication technology).

[0086] FIG. 7 shows a cross-sectional view of a leadless package 100 according to an exemplary embodiment.

[0087] In the leadless configuration according to FIG. 7, substantially no leads extend beyond the encapsulant 112. Only small connection structures 220 are provided which connect the package 100 with a mounting base 152 such as a printed circuit board (PCB). The connection structures 220 may be connected with pads of the mounting base 152, for instance by soldering or sintering. The chips 104, 106 are embedded within the encapsulant 112 and are therefore not visible according to FIG. 7.

[0088] FIG. 8 shows a cross-sectional view of a leaded package 100 according to another exemplary embodiment.

[0089] The leaded package 100 according to FIG. 8 differs from the leadless package 100 according to FIG. 7 in that according to FIG. 8 leads 240 of the chip carrier 102 extend beyond the encapsulant 112. The leads 240 serve for electrically contacting the package 100 with the mounting base 152. In the shown embodiment, the exposed leads 240 are configured in a gull wing configuration having some elasticity enabling for a springy equilibration, for instance in the event of thermal loads.

[0090] FIG. 9 illustrates schematically a vehicle 160 comprising a power package 100 according to an exemplary embodiment. More specifically, the power package 100 may form part of a control block 162 controlling operation of electric motor/battery block 164. Hence, a package 100 or power module according to an exemplary embodiment may be used for an automotive application.
