Latest Patents

One of his latest patents is a method for making a Schottky diode that is compatible with high-performance applications. This method involves creating a Schottky diode structure simultaneously with a polysilicon contact structure to a transistor. In a single process step, a polysilicon layer is patterned to expose a single crystal semiconductor region over one portion of a substrate, while leaving portions of the polysilicon layer intact over other portions of the substrate. Multi-layer metal electrodes are then deposited and patterned to form a rectifying Schottky contact to the exposed single crystal region and to form an ohmic contact to the exposed polysilicon.

Another notable patent is for forming a lateral bipolar transistor. This structure is formed in a laterally isolated semiconductor device tub of a first conductivity type. First and second trenches are etched in the device tub and filled with doped polysilicon of a second conductivity type to form an emitter and a collector. The portion of the tub between the emitter and collector regions forms a base region. This configuration provides a high emitter area and minimal device surface area, greatly easing the layout of integrated circuits using the transistor structure.
