Latest Patents

Among his latest patents, Zorinsky has introduced a pioneering method of forming a recessed contact bipolar transistor. This invention discloses a scaled, self-aligned bipolar transistor and a fabrication method that is compatible with MOSFET device structures. The transistor's intrinsic base region is strategically formed in an isolated epitaxial region, and through a meticulous process involving polysilicon deposition, patterning, and etching, emitter regions are created. Following this, an oxide cap and first sidewall oxide spacers are applied to the polysilicon emitters. The single crystal silicon undergoes etching using the oxide-covered emitters as a mask to form recessed regions in the epitaxial layer. Subsequently, the extrinsic base region is implanted with appropriate dopants. A secondary sidewall oxide spacer is built on the structure, and a heavily doped collector contact region is established, ensuring self-alignment to prevent contact issues between the base and collector. This innovation is set to reduce contact resistance by siliciding the emitter, base, and collector contact regions.
