Title: Innovations of Inventor Allan Ward
Introduction
Allan Ward is a notable inventor based in Durham, NC (US), recognized for his contributions to semiconductor technology. He holds a total of 10 patents, showcasing his expertise and innovative spirit in the field.
Latest Patents
Among his latest patents is the invention titled "Edge termination structures for silicon carbide devices." This patent describes an edge termination structure for a silicon carbide semiconductor device that includes a plurality of spaced apart concentric floating guard rings. These guard rings at least partially surround a silicon carbide-based junction, with an insulating layer on the floating guard rings and a silicon carbide surface charge compensation region between the floating guard rings and adjacent the surface of the silicon carbide layer. Additionally, a silicon nitride layer is positioned on the silicon carbide layer, along with an organic protective layer on the silicon nitride layer. The patent also discusses methods of forming these edge termination structures.
Another significant patent is the "Metallization structure for high power microelectronic devices." This invention includes a semiconductor device structure that features a wide-bandgap semiconductor portion selected from silicon carbide and the Group III nitrides. The interconnect structure made to the semiconductor portion consists of at least two diffusion barrier layers alternating with two respective high electrical conductivity layers. The design ensures that the coefficients of thermal expansion of the layers are managed to prevent strain that could exceed the bond strength between them.
