Semiconductor device, method for manufacturing the same, and power conversion device
In a method for manufacturing a semiconductor device, a plurality of first provisional fixing portions are supplied on a front surface of a substrate such that the plurality of first provisional fixing portions are spaced from each other and thus dispersed. A first solder layer processed into a plate to be a first soldering portion is disposed in contact with the plurality of first provisional fixing portions. A semiconductor chip is disposed on the first solder layer. In addition a conductive member in the form of a flat plate is disposed thereon via a second provisional fixing portion and a second solder layer. A reflow process is performed to solder the substrate, the semiconductor chip and the conductive member together.
Shielded electronic package and method of fabrication
An electronic device package includes a first die coupled to a substrate, a second die coupled with the first die, and a spacer element coupled to the second die to form a stacked structure that includes the first die, the second die, and the spacer element. An electrically conductive shield overlies the stacked structure. The shield has a first end coupled to the spacer element and a second end coupled to the substrate. Inter-chip bond wires may electrically interconnect the first and second dies, and the shield may additionally overlie the bond wires. The spacer element may extend above a surface of the second die at a height that is sufficient to prevent the shield from touching the inter-chip bond wires.

Semiconductor device
A semiconductor chip (6) having flexibility is bonded to a heat radiation material (4) with solder. The semiconductor chip (6) is pressed by a tip of a pressing member (9,11) from an upper side. As a result, convex warpage of the semiconductor chip (6) can be suppressed. Furthermore, since voids can be prevented from remaining in the solder (7), the heat radiation of the semiconductor device can be enhanced.
