Latest Patents

One of his latest patents is titled "Silicon-rich nickel-silicide ohmic contacts for SiC semiconductor devices." This patent discloses a method of producing an ohmic contact and a resulting ohmic contact structure. The method involves forming a deposited film of nickel and silicon on a silicon carbide surface at a temperature that prevents either element from reacting with silicon carbide. The atomic fraction of silicon in the deposited film is greater than that of nickel. The process includes heating the deposited film to a temperature where nickel-silicon compounds form, while also ensuring that free carbon does not exist during the annealing process.

Another significant patent by Wieber is related to "Metal-semiconductor field effect transistors (MESFETs) having self-aligned structures." This patent provides a design for a MESFET that includes a source region, a drain region, and a gate positioned between them. A p-type conductivity layer is self-aligned beneath the source region, enhancing the efficiency and performance of the device.
