Semiconductor module and method for manufacturing semiconductor module
Provided is a semiconductor module enabling to effectively reduce, with a relatively simple structure, a thermal strain occurring in a bonding section between a semiconductor chip and other conductor members. The semiconductor module is characterized by being provided with: a first wiring layer; a semiconductor element bonded on the first wiring layer via a first bonding layer; a first electrode bonded on the semiconductor element via a second bonding layer; a second electrode connected on the first electrode; and a second wiring layer connected on the second electrode. The semiconductor module is also characterized in that: the width of the second electrode, said width being in the short-side direction, is more than the thickness of the first electrode; and the second electrode is disposed at a position off the center position of the semiconductor element.
GANG CLIP
An integrated circuit (IC) package includes a lead frame and a first die attached to the lead frame. The IC package also includes a first clip attached to first die and the lead frame. The IC package further includes a second die attached to first clip and the lead frame. The IC package still further includes a second clip with a clip foot adhered to the lead frame on a first side of the second clip, the second clip extending to and contacting a side of the second die via a layer of solder paste. The second clip includes a sawn or lased edge at a second side of the second clip opposing the first side of the second clip.
Integrated circuit (IC) die attached between an offset lead frame die-attach pad and a discrete die-attach pad
An integrated circuit (IC) package, e.g., a power MOSFET package, may include a lead frame including (a) a main lead frame structure including a plurality of leads and defining or lying in a main lead frame plane, and (b) an offset lead frame die-attach pad (DAP) defining or lying in an offset plane that is offset from the main lead frame plane. The power IC package may further include a semiconductor die having a first side attached to the offset lead frame DAP, and a conductive element attached to both (a) a second side of the semiconductor die and (b) the main lead frame structure. The lead frame including the offset DAP may emulate the functionality of a copper clip, thus eliminating the need for the copper clip. The power IC package may also exhibit enhanced heat dissipation capabilities.

Semiconductor device and manufacturing method thereof
On the assumption that a pair of hanging parts is provided in a lead frame and a clip includes a main body part and a pair of extension parts, the pair of the extension parts is mounted and supported on the pair of the hanging parts. Accordingly, the clip is mounted on a lead (one point) and the pair of the hanging parts (two points), and the clip is supported by the three points.
