Latest Patents

Chun Hu's latest patents include a method for integrating SiGe NPN and vertical PNP devices. According to one exemplary embodiment, this method involves forming an insulating layer over both the NPN and PNP regions of a substrate. The process continues with the formation of a buffer layer on the insulating layer, followed by creating an opening in both layers in the NPN region, which exposes the substrate. A semiconductor layer is then formed on the buffer layer and within the opening in the NPN region. This semiconductor layer consists of a first portion situated in the opening, forming a single crystal base of the NPN device, and a second portion situated on the buffer layer in the PNP region, forming a polycrystalline emitter of the vertical PNP device.
