Latest Patents

Renbeck's latest patents include a method of making a high-performance MESFET with multiple quantum wells. This invention describes a superheterojunction Field Effect Transistor (FET) with a multi-region channel on a Silicon (Si) substrate. The FET can be classified as a Metal Semiconductor FET (MESFET) or a Junction FET (JFET). The multi-region channel consists of a first region of Si extending from the FET's source to a point under the FET's gate, a second region made of a superlattice of alternating Si and SiGe layers, and a third region of Si extending under the first two regions. The first region features a laterally graded dopant that creates an accelerating electric field, while the superlattice structure enhances electron mobility and transit velocity.

Another significant patent is the method of making a carrier conduction conductor-insulator semiconductor. This invention details a Conductor Insulator Semiconductor (CIS) heterojunction transistor built on a silicon (Si) substrate. The process involves depositing a layer of n-type Si on the substrate, forming a trench filled with an insulator, and depositing a layer of p-type Si1-zGez. The design includes a p+ base contact region and an n-type dopant that forms a collector region, ultimately leading to the creation of a highly efficient transistor.
