Semiconductor device including antistatic die attach material
A semiconductor device includes a substrate, a semiconductor die, and an antistatic die attach material between the substrate and the semiconductor die. The antistatic die attach material includes a mixture of a nonconductive adhesive material and carbon black or graphite. In one example, the antistatic die attach material has a resistivity between 10.sup.1 Ω.Math.cm and 10.sup.10 Ω.Math.cm.
Spot-solderable leads for semiconductor device packages
A semiconductor device that has at least one semiconductor chip attached to a leadframe made of sheet metal of unencumbered full thickness. The leadframe has leads of a first subset that alternate with leads of a second subset. The leads of the first and second subsets have elongated straight lead portions that are parallel to each other in a planar array. A cover layer of insulating material is located over portions of un-encapsulated lead surfaces. The portions of the leads of the first and second subsets that don't have the cover layer have a metallurgical configuration that creates an affinity for solder wetting.
ELECTRONIC DEVICE AND ELECTRONIC DEVICE MOUNTING STRUCTURE
An electronic device includes: an electronic element having an element obverse surface and an element reverse surface spaced apart from each other in a first direction, the element obverse surface being provided with an obverse-surface electrode; a resin member having a resin reverse surface facing in a same direction as the element reverse surface, the resin member covering the electronic element; and an electrically conductive member supporting the electronic element and electrically connected to the electronic element. The electrically conductive member has a first exposed region, a second exposed region and a third exposed region each of which is exposed from the resin reverse surface.

Combined packaged power semiconductor device
A combined packaged power semiconductor device includes flipped top source low-side MOSFET electrically connected to top surface of a die paddle, first metal interconnection plate connecting between bottom drain of a high-side MOSFET or top source of a flipped high-side MOSFET to bottom drain of the low-side MOSFET, and second metal interconnection plate stacked on top of the high-side MOSFET chip.
