Patents by Inventor Stephen R. Cebenko

Stephen R. Cebenko 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).

  • Integrated circuit base transistor structure and associated programmable cell library
    Patent number: 6781170
    Abstract: A base transistor structure and associated programmable cell library compatible with standard cell computer-aided design (CAD) tools are disclosed. In an illustrative embodiment of the invention, the base transistor structure is symmetric about one or more axes, and extends only a single grid of a standard cell CAD tool in width. The base transistor structure is advantageously configured in a manner that permits the utilization of gate isolation to separate active transistors in adjacent base transistor structures. The base transistor structure can be used to implement a programmable cell technology that is fully compatible with standard cell CAD tools.
