Latest Patents

Tsyr-Shyang Liou holds a patent for a "Fabrication process for a single polysilicon layer, bipolar junction transistor featuring reduced junction capacitance." This patent describes a process for fabricating a BJT that features reduced junction capacitance, achieved by decreasing the dimensions of both extrinsic and intrinsic base regions. The BJT device is designed with a single polysilicon level used for the emitter structure, while the extrinsic and intrinsic base regions are accommodated in an epitaxial silicon layer. This layer is grown on an underlying silicon active device region, which is in turn supported by a silicon seed layer that overlays insulator isolation regions. The patent also discusses the formation of a boron-doped intrinsic base region, which can be created in an undoped version of the epitaxial silicon layer or contained within the as-deposited epitaxial silicon or silicon-germanium layers. Tsyr-Shyang Liou has 1 patent to his name.
