Latest Patents

Kurachi's latest patents include a method for manufacturing a semiconductor device and a semiconductor device itself. The method involves forming a source electrode and a drain electrode on a nitride semiconductor layer that is situated on a SiC substrate. Additionally, it includes the formation of a gate electrode with a laminated structure comprising a Ni layer and an Au layer. This gate electrode is positioned between the source and drain electrodes. Furthermore, the method outlines the creation of a first metal film adjacent to the source electrode and a second metal film that contacts both the source electrode and the first metal film. The process also describes forming a hole that connects to the first metal film from the back surface of the SiC substrate, along with a metal via that extends from the back surface into the hole.

The semiconductor device patent describes a device that features a substrate with a primary surface and a secondary surface. The primary surface hosts a semiconductor active device. This device includes a base metal layer on the secondary surface and within a substrate via, where a vacancy is formed. An additional metal layer is placed on the base metal layer, exhibiting different wettability against solder compared to the base metal layer. This design allows the solder to be in contact with the base metal layer while being repelled by the additional metal layer.
