Latest Patents

One of Dean's latest patents is a three-dimensional etching process. This method involves forming three-dimensional structures on a substrate through a single reactive ion etching run. A mask is created on the substrate before a series of iterations are performed. Each iteration includes a mask etch and a substrate etch, allowing for a reduction in the mask area and the exposure of additional substrate areas.

Another significant patent is for a high-frequency field effect transistor (FET) with carrier extraction to reduce intrinsic conduction. This FET employs base biasing to minimize the intrinsic contribution to conduction and reduce leakage current. It consists of four successive layers: a p-InSb base layer, an InAlSb barrier layer, a π intrinsic layer, and an insulating SiO layer. The design incorporates p-source and drain regions implanted in the intrinsic layer, establishing the FET channel in the intrinsic layer. This innovative design helps maintain channel straightness and enables a high current gain cut-off frequency.
