Latest Patents

One of Ken Liao's latest patents is titled "Method of forming a super self-aligned hetero-junction bipolar transistor." This invention provides a method for creating a super self-aligned bipolar transistor with enhanced electrical characteristics. The power gain and frequency response of the transistor are improved by horizontally etching an area for the base region that is wider than the active emitter and collector regions. By removing polysilicon layers within the device, the base region resistance decreases, and unwanted capacitive effects are minimized.

Another significant patent is the "Method of forming a shallow and deep trench isolation (SDTI) suitable for silicon on insulator (SOI) substrates." This method includes forming a pair of deep trenches through a silicon on insulator (SOI) layer without substantially disturbing an underlying buried oxide (BOX) layer. After forming the deep trenches, they are filled with suitable electrical isolating materials and etched back to achieve a substantially planarized top surface. This process allows for subsequent steps, including filling the shallow trench, annealing, and chemical-mechanical polishing.
