Latest Patents

One of Pengfei Wu's latest patents focuses on high-frequency heterojunction bipolar transistor devices. This patent details techniques for integrating lateral HBT devices into a silicon on insulator (SOI) CMOS process. The approaches described could also be applied to Fin Field-Effect Transistors (FinFETs). The first technique utilizes a CMOS replacement gate process, typically associated with partially depleted SOI (PDSOI) or fully depleted SOI (FDSOI) processes. The second technique is independent of the CMOS process and can accommodate silicon germanium (SiGe) and/or III-V materials. Both techniques include a self-aligned base contact and can be used to construct both NPN and PNP transistors with varied peak fT and breakdown voltages.

Another significant patent by Wu involves a heavily doped buried layer designed to reduce MOSFET off capacitance. This invention describes a metal-oxide semiconductor field effect transistor (MOSFET) that includes a source region and a drain region of a first conductivity type. The MOSFET also features a body region of a second conductivity type, which underlies at least a portion of the source and drain regions. The buried region of the first conductivity type is configured to reduce capacitance between the source and drain regions in response to an indicated voltage applied between the body region and the buried region.
