Semiconductor device and method of manufacturing semiconductor device
A packaged electronic device includes a substrate comprising a die pad and a lead spaced apart from the die. An electronic device is attached to the die pad top side. A conductive clip is connected to the substrate and the electronic device, and the conductive clip comprises a plate portion attached to the device top side with a conductive material, a clip connecting portion connected to the plate portion and the lead, and channels disposed to extend inward from a lower side of the plate portion above the device top side. The conductive material is disposed within the channels. In another example, the plate portion comprises a lower side having a first sloped profile in a first cross-sectional view such that an outer section of the first sloped profile towards a first edge portion of the plate portion is spaced away from the electronic device further than an inner section of the first sloped profile towards a central portion of the plate portion. Other examples and related methods are also disclosed herein.
SEMICONDUCTOR DEVICE
A semiconductor device including a substrate; a chip on which a surface electrode is formed; and a lead. The lead includes a first electrode connecting portion disposed on the surface electrode and electrically connected to the surface electrode of the chip via a conductive bonding material; a second electrode connecting portion electrically connected to an electrode portion of a wiring pattern. A lead connected to the first electrode connecting portion and the second electrode connecting portion. The lead further has a thermal shrinking stress equalizing structure on a portion of an outer periphery of the first electrode connecting portion. The lead is configured to make a thermal shrinking stress applied to a conductive bonding material between the first electrode connecting portion and the surface electrode equal.
WIRING MEMBER AND SEMICONDUCTOR MODULE INCLUDING SAME
In a wiring member, an element connection portion, a plate connection portion, and an upper surface portion are at height positions different from one another. The element connection portion has a through hole, and the plate connection portion has a through hole and a chamfer. The upper surface portion which is not connected to another portion, has projections asymmetrically disposed on both side surfaces thereof. Owing to these features, the type, the orientation, and the front and the back of the wiring member can be easily distinguished. Accordingly, it is possible to prevent incorrect assembling of the wiring member in a semiconductor module.
