Latest Patents

Cumbo holds a patent for a method of forming power semiconductor devices with controllable characteristics. This patent, which is titled "Method of forming power semiconductor devices with controllable," describes a process in which a sacrificial N shelf layer is grown on a P+ semiconductor substrate. This layer is designed to contain the out-diffusion of dopant from the substrate. An N+ buffer layer is then grown on the N shelf layer, followed by an N- epitaxial layer on the N+ buffer layer. The presence of the N shelf layer, which is consumed by the substrate dopant during further device fabrication, allows for accurate control of the integrated dopant level of the N+ buffer layer in the finished device. Cumbo has 1 patent to his name.
