Latest Patents

Eldridge's latest patents include a method of fabricating a semiconductor structure. This invention provides a wet etch and method for preparing a semiconductor device structure from a silicon carbide wafer. The first embodiment of the wet etch comprises a vessel containing a tetrahydrofurfuryl alcohol and potassium nitrite etching solution, an electrode, and a wafer support for positioning the silicon carbide wafer within the etching solution. A voltage source is coupled with the electrode and the wafer support. The second embodiment includes a wafer carrier for holding at least one wafer, a polishing plate adjacent to the wafer carrier, and an applicator for depositing an etching solution on the polishing plate's surface.

Another significant patent is a method for epitaxially growing α-silicon carbide on an a-axis substrate. This method involves forming a section from the SiC crystal by making parallel cuts in the crystal, which are aligned with the c-axis. A gas mixture containing hydrocarbon and silane is then passed over one of the a-face surfaces of the section, allowing the hydrocarbon and silane to react and form an epitaxial layer of SiC at approximately 1450°C.
