[0019] Referring to
[0020] Each of the first and second metallization layers 111, 112 may consist of or include one of the following materials: copper; a copper alloy; aluminum; an aluminum alloy; any other metal or alloy that remains solid during the operation of the power semiconductor module arrangement. The substrate 10 may be a ceramic substrate, that is, a substrate in which the dielectric insulation layer 11 is a ceramic, e.g., a thin ceramic layer. The ceramic may consist of or include one of the following materials: aluminum oxide; aluminum nitride; zirconium oxide; silicon nitride; boron nitride; or any other dielectric ceramic. For example, the dielectric insulation layer 11 may consist of or include one of the following materials: Al.sub.2O.sub.3, AlN, SiC, BeO or Si.sub.3N.sub.4. For instance, the substrate 10 may, e.g., be a Direct Copper Bonding (DCB) substrate, a Direct Aluminum Bonding (DAB) substrate, or an Active Metal Brazing (AMB) substrate. Further, the substrate 10 may be an Insulated Metal Substrate (IMS). An Insulated Metal Substrate generally comprises a dielectric insulation layer 11 comprising (filled) materials such as epoxy resin or polyimide, for example. The material of the dielectric insulation layer 11 may be filled with ceramic particles, for example. Such particles may comprise, e.g., SiO.sub.2, Al.sub.2O.sub.3, AlN, or BN and may have a diameter of between about 1 m and about 50 m. The substrate 10 may also be a conventional printed circuit board (PCB) having a non-ceramic dielectric insulation layer 11. For instance, a non-ceramic dielectric insulation layer 11 may consist of or include a cured resin.
[0021] The substrate 10 is arranged in a housing 7. In the example illustrated in
[0022] One or more semiconductor bodies 20 may be arranged on the at least one substrate 10. Each of the semiconductor bodies 20 arranged on the at least one substrate 10 may include a diode, an IGBT (Insulated-Gate Bipolar Transistor), a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), a JFET (Junction Field-Effect Transistor), a HEMT (High-Electron-Mobility Transistor), and/or any other suitable semiconductor element.
[0023] The one or more semiconductor bodies 20 may form a semiconductor arrangement on the substrate 10. In
[0024] The power semiconductor module arrangement 100 illustrated in
[0025] The power semiconductor module arrangement 100 may further include an encapsulant 5. Encapsulant 5 may consist of or include a silicone gel or may be a rigid molding compound, for example. The encapsulant 5 may at least partly fill the interior of the housing 7, thereby covering the components and electrical connections that are arranged on the substrate 10. The terminal elements 40 may be partly embedded in the encapsulant 5. At least their second ends 42, however, are not covered by the encapsulant 5 and protrude from the encapsulant 5 through the housing 7 to the outside of the housing 7. The encapsulant 5 is configured to protect the components and electrical connections of the power semiconductor module 100, in particular the components arranged on the substrate 10 inside the housing 7, from certain environmental conditions and mechanical damage.
[0026] The layout of a semiconductor arrangement (e.g., semiconductor bodies 20, electrical connections 3, terminal elements 40, etc.) generally may be chosen to minimize the required size of the at least one substrate while, at the same time, also minimizing an unequal distribution of current densities, electrical losses, and thermal stress. Symmetry is often essential with respect to gate driving and parasitic inductances. Lateral semiconductor devices such as, e.g., GaN HEMTs, which have all contact pads (e.g., gate, source and drain contact pads) arranged on their top side and no contact pads on their bottom side, generally pose problems with regard to a symmetrical arrangement of the devices, especially for devices that are operated in parallel. A symmetrical arrangement of lateral devices often results in increased chip manufacturing costs, complex designs, and decreased flexibility in the production line.
[0027] In order to avoid the above mentioned drawbacks, a semiconductor module arrangement according to embodiments of the disclosure comprises a substrate 10 comprising a dielectric insulation layer 11 and a first metallization layer 111 arranged on a surface of the dielectric insulation layer 11. The first metallization layer 111 comprises a first section 111.sub.1, a second section 111.sub.2, and a third section 111.sub.3. A first semiconductor body 201 and an identical second semiconductor body 202 are arranged on the first metallization layer 111, wherein each of the first semiconductor body 201 and the second semiconductor body 202 has a first contact pad 21.sub.1, 22.sub.1, a second contact pad 21.sub.2, 22.sub.2, and a third contact pad 21.sub.3, 22.sub.3 arranged on a top side of the respective semiconductor body 201, 202 that faces away from the substrate 10. That is, the first and second semiconductor body 201, 202 are lateral semiconductor devices. As the first semiconductor body 201 is identical to the second semiconductor body 202, the semiconductor bodies 201, 202 are of the same type (e.g., GaN HEMTs) and have identical switching and transmittance characteristics. Further, the contact pads 21.sub.1, 22.sub.1, 21.sub.2, 22.sub.2, 21.sub.3, 22.sub.3 are arranged identically on the top sides of the first and second semiconductor body 201, 202 (identical contact pad layout). In other words, the first semiconductor body 201 may be readily replaced by the identical second semiconductor body 202, and vice versa, without affecting the electrical properties and the function of the semiconductor module arrangement. The third contact pad 21.sub.3 of the first semiconductor body 201 is electrically coupled to the third section 111.sub.3 of the first metallization layer 111 by means of a first electrical connection element 3.sub.21, and the third contact pad 22.sub.3 of the second semiconductor body 202 is electrically coupled to the third section 111.sub.3 of the first metallization layer 111 by means of a second electrical connection element 3.sub.22. The semiconductor module arrangement further comprises at least one third terminal element 40.sub.3 arranged on the third section 111.sub.3. In this way, a control signal may be provided (e.g., from outside of a housing in which the semiconductor module arrangement may be arranged) to the third section 111.sub.3 and from there, via the first electrical connection element 3.sub.21 to the first semiconductor body 201, and via the second electrical connection element 3.sub.22 to the second semiconductor body 202.
[0028] A first current path 8021 between the third contact pad 21.sub.3 of the first semiconductor body 201 and the at least one third terminal element 40.sub.3 (e.g., a third terminal element 40.sub.3 of the at least one third terminal element 40.sub.3 that is arranged closest to the first electrical connection element 3.sub.21) provides identical voltage and current transfer characteristics as a second current path 80.sub.22 between the third contact pad 22.sub.3 of the second semiconductor body 202 and the at least one third terminal element 40.sub.3 (e.g., a third terminal element 40.sub.3 of the at least one third terminal element 40.sub.3 that is arranged closest to the second electrical connection element 3.sub.22). Each of the first and second electrical connection elements 3.sub.21, 3.sub.22 comprises one or more bonding wires, one or more bonding ribbons, a connection rail, or a section of an additional metallization layer of the substrate 10 that is contacted by corresponding vias. In this way, a control signal provided via the third terminal element 40.sub.3 reaches the third contact pad 21.sub.3 of the first semiconductor body 201 and the third contact pad 22.sub.3 of the second semiconductor body 202 at the same time and with similar signal properties. That is, for example, that the third contact pads 21.sub.3, 22.sub.3 will have an essentially identical potential (or voltage) when a control signal is applied to the third terminal element 40.sub.3. This allows to operate the first semiconductor body 201 and the second semiconductor body 202 in a highly symmetrical way. That is, the first semiconductor body 201 and the second semiconductor body 202 will switch on or off at essentially the same time. Further, the first semiconductor body 201 and the second semiconductor body 202 will have identical current and voltage transients during the switching operations as well as, for example, the same current densities during operation. To achieve this, the first current path 80.sub.21 and the second current path 80.sub.22 may exhibit at least one of essentially identical or identical ohmic behaviors, essentially identical or identical inductive behaviors, and essentially identical or identical capacitive behaviors, for example. (Essentially) identical ohmic behaviors, (essentially) identical inductive behaviors and (essentially) identical capacitive behaviors of the current paths 80.sub.21, 80.sub.22 generally result in an impedance difference of the two current paths 80.sub.21, 80.sub.22 that is significantly smaller than an (input) impedance difference of the first and second semiconductor bodies 201, 202. (Input) impedance differences of the first and second semiconductor bodies 201, 202 may result from typical production variations, for example. In other words, a sum of the impedances of the different elements of the first current path 80.sub.21 may be (essentially) identical to a sum of the impedances of the different elements of the second current path 80.sub.22. The term identical as used herein should be construed such that the related property of different entities such as, e.g., the ohmic behaviors of the first and second current paths 80.sub.21, 80.sub.22, are very similar. It may also be said that the different entities may be designed such that the related properties are exactly the same, but slight deviations may occur based on manufacturing tolerances. Manufacturing tolerances may vary between different applications and different manufacturing processes used to produce the different entities.
[0029] The third contact pads 21.sub.3, 22.sub.3 may form or may be coupled to a control electrode (e.g., gate electrode) of the first and second semiconductor body 201, 202, respectively. In particular, each of the first and second semiconductor body 201, 202 may comprise a control electrode and a controllable load path between a first load electrode and a second load electrode. The first contact pads 21.sub.1, 22.sub.1 may form or may be coupled to the respective first load electrode (e.g., drain electrode), and the second contact pads 21.sub.2, 22.sub.2 may form or may be coupled to the respective second load electrode (e.g., source electrode) of the first and second semiconductor body 201, 202, for example.
[0030] Now referring to
[0031] The first current path 80.sub.21 is formed by the first electrical connection element 3.sub.21 and a first segment 111.sub.321 of the third section 111.sub.3 arranged between the first connection point and the third terminal element 40.sub.3, and the second current path 80.sub.22 is formed by the second electrical connection element 3.sub.22 and a second segment 111.sub.322 of the third section 111.sub.3 arranged between the second connection point and the third terminal element 40.sub.3. This is schematically illustrated in further detail in
[0032] Arranging the first semiconductor body 201 and the second semiconductor body 202 point symmetrical about a center of symmetry P1, however, is only one example of how symmetrical driving of the semiconductor bodies 201, 202 can be achieved. Now referring to

[0035] In contrast to this, in the example illustrated in
[0036] Now referring to
[0037] It is generally also possible that more than two third terminal elements 40.sub.3 are arranged on the third section 111.sub.3 and between the first connection point and the second connection point. Irrespective of the number of third terminal elements 40.sub.3 arranged on the third section 111.sub.3, the first current path 80.sub.21 is formed by the first electrical connection element 3.sub.21 and a first segment 111.sub.321 of the third section 111.sub.3 arranged between the first connection point and the at least one third terminal element 40.sub.3 (e.g., the third terminal element 40.sub.3 of the at least one third terminal element 40.sub.3 that is arranged closest to the first connection point), and the second current path 80.sub.22 is formed by the second electrical connection element 3.sub.22 and a second segment 111.sub.322 of the third section 111.sub.3 arranged between the second connection point and the at least one third terminal element 40.sub.3 (e.g., the third terminal element 40.sub.3 of the at least one third terminal element 40.sub.3 that is arranged closest to the second connection point). It is even possible, if two or more third terminal elements 40.sub.3 are arranged on the third section 111.sub.3, that one or more of the two or more third terminal elements 40.sub.3 are not arranged between the first connection point and the second connection point.
[0038] What has been described with respect to
[0039] In all examples, the third section 111.sub.3 and the at least one third terminal element 40.sub.3 arranged thereon may be arranged distant from the first semiconductor body 201 and the second semiconductor body 202 in the second horizontal direction z. Further, in all examples, the first contact pad 21.sub.1 of the first semiconductor body 201 and the first contact pad 22.sub.1 of the second semiconductor body 202 may be electrically coupled to the first section 111.sub.1 of the first metallization layer 111, and the second contact pad 21.sub.2 of the first semiconductor body 201 and the second contact pad 22.sub.2 of the second semiconductor body 202 may be electrically coupled to the second section 111.sub.2 of the first metallization layer 111. According to one example, the second contact pad 21.sub.2 of the first semiconductor body 201 and the second contact pad 22.sub.2 of the second semiconductor body 202 may be source pads, and the first contact pad 21.sub.1 of the first semiconductor body 201 and the first contact pad 22.sub.1 of the second semiconductor body 202 may be drain pads. Each of the first contact pad 21.sub.1 of the first semiconductor body 201 and the first contact pad 22.sub.1 of the second semiconductor body 202 may be electrically coupled to the first section 111.sub.1 of the first metallization layer 111 by means of an electrical connection element 3, and each of the second contact pad 21.sub.2 of the first semiconductor body 201 and the second contact pad 22.sub.2 of the second semiconductor body 202 may be electrically coupled to the second section 111.sub.2 of the first metallization layer 111 by means of an electrical connection element 3. Each of the electrical connection elements 3 may comprise one or more bonding wires, one or more bonding ribbons, a connection rail, or a section of an additional metallization layer of the substrate 10 that is contacted by corresponding vias, for example. The first semiconductor body 201 and the second semiconductor body 202 may be arranged on the second section 111.sub.2 of the first metallization layer 111. That is, the first semiconductor body 201 and the second semiconductor body 202 may be arranged on that section of the first metallization layer to which their respective second contact pads 21.sub.2, 22.sub.2 are electrically coupled (e.g., semiconductor bodies arranged on source potential).
[0040] The second section 111.sub.2 of the first metallization layer 111 may horizontally surround the third section 111.sub.3, as is schematically illustrated in
[0041] In the semiconductor module arrangement as schematically illustrated in
[0042] Now referring to
[0043] The semiconductor module arrangements according to the different embodiments of the disclosure that have been exemplarily discussed above provide gate driving symmetry and, optionally, symmetry of load currents for lateral semiconductor devices. The semiconductor module arrangements as discussed above may be used as sub-structures in more complex topologies, at least the arrangements as exemplarily discussed with respect to
[0044] Now referring to
[0045] The semiconductor module arrangement further comprises at least one fourth terminal element 40.sub.32 arranged on the fourth section 111.sub.32. The number of fourth terminal elements 40.sub.32 may correspond to the number of third terminal elements 40.sub.31 in order for the two sub-systems to be symmetrical to each other (with respect to the current paths). A third current path between the third contact pad of the third semiconductor body 203 and the at least one fourth terminal element 40.sub.32 (e.g., a fourth terminal element 40.sub.32 of the at least one fourth terminal element 40.sub.32 that is arranged closest to the third electrical connection element 3.sub.23) provides identical voltage and current transfer characteristics as a fourth current path between the third contact pad of the fourth semiconductor body 204 and the at least one fourth terminal element 40.sub.32 (a fourth terminal element 40.sub.32 of the at least one fourth terminal element 40.sub.32 that is arranged closest to the fourth electrical connection element 3.sub.24). Similar to what has been discussed above with respect to the first sub-structure, each of the third and fourth electrical connection elements 3.sub.23, 3.sub.24 comprises one or more bonding wires, one or more bonding ribbons, a connection rail, or a section of an additional metallization layer of the substrate 10 that is contacted by corresponding vias, for example.
[0046] The second sub-structure, similar to the first sub-structure, provides gate driving symmetry and, optionally symmetry of load currents. It is also possible that the first sub-structure and second sub-structure provide identical voltage and current transfer characteristics. That is, the first current path 80.sub.21 may provide identical voltage and current transfer characteristics not only as the second current path 80.sub.22, but also as the third current path and the fourth current path.
[0047] The first contact pad of the third semiconductor body 203 and the first contact pad of the fourth semiconductor body 204 may be electrically coupled to the first section 111.sub.1 of the first metallization layer 111, and the second contact pad of the third semiconductor body 203 and the second contact pad of the fourth semiconductor body 204 may be electrically coupled to the second section 111.sub.2 of the first metallization layer 111.
