Latest Patents

One of Hanson's latest patents is a process for manufacturing a semiconductor BICMOS device. This process involves creating bipolar and CMOS transistors on a p-type silicon substrate. The silicon substrate features typical n+ buried wells and field oxide regions to isolate individual transistor devices. The process includes the creation of stacks of material over the gate elements of the CMOS devices and over the emitter elements of the bipolar transistors. These stacks consist of a silicon dioxide gate layer in contact with the epitaxial layer of the substrate, and a polycrystalline silicon layer over the emitter elements. Additionally, walls of silicon dioxide are formed around the stacks to insulate the materials within from those deposited outside. The polycrystalline silicon layers are implanted with appropriate dopants to create the source and drain elements of the CMOS devices and the emitter elements of the bipolar devices during a heating step. A tungsten layer is then deposited over the polycrystalline layer to provide a conductive coupling to aluminum electrodes.
