Latest Patents

Among his latest patents is the invention of a self-aligned bipolar transistor using selective polysilicon growth. This innovative design features a polysilicon layer with a cavity formed therein, allowing for improved transistor performance. The process involves the use of a thin seed layer over an epitaxial layer, followed by the formation of dielectric layers that define the polysilicon layer and cavity. The exposed seed layer is then utilized for selective growth of the polysilicon layer, ultimately leading to the implantation of the base and formation of the emitter.

Another significant patent by Favreau is the single polysilicon layer transistor with reduced emitter and base. This design incorporates a substantially vertical emitter contact region, which minimizes the base resistance of the device. The self-aligned process ensures that heavily doped silicided regions are positioned adjacent to the emitter, enhancing the overall efficiency of the integrated circuit.
