Karl J. Yoder has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of increasing mechanical properties of semiconductor substrates
    Publication number: 20040110013
    Abstract: Semiconductor wafers exhibiting increased mechanical strength and reduced susceptibility to fracture and methods of making the same are disclosed. The improved mechanical strength arises from a thin coating of a refractory material deposited on the backside of the wafer. Preferably, the coating is comprised of a ceramic. More preferably, the coating is comprised of silicon carbide. Also disclosed are methods for evaluating different coating materials.
    Type: Application
