Patents by Inventor Karen A. Bard

Karen A. Bard 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).

  • Patent number: 7089513
    Abstract: A method, system and program product for designing an integrated circuit (IC) for signal integrity. The invention conducts a signal integrity analysis on an IC design; identifies any field effect transistor (FET) that causes a signal integrity failure in the case that the IC design fails the signal integrity analysis; and modifies an edge of a failing FET that is closer than a threshold distance to a well edge. The invention eliminates the manual, iterative procedure for determining the device causing a signal integrity failure due to well proximity effects.
    Type: Grant

  • Patent number: 7073139
    Abstract: A method for determining contact location for embedded dynamic random access memory (eDRAM) formed in a silicon-on-insulator (SOI) substrate includes reviewing contact design data for an eDRAM device and discarding contact locations corresponding to contact shapes within a support area of the eDRAM device. Contact locations corresponding to bitline contacts to storage cells within the eDRAM device are saved and outputted to a custom design level to be used in forming body contacts for the eDRAM formed in the SOI substrate.

  • Patent number: 6998865
    Abstract: A test arrangement includes a semiconductor device, a first conductive pad electrically connected to the semiconductor device, a second conductive pad, and a programmable fuse. The second conductive pad is electrically connected to the semiconductor device through the programmable fuse.

  • Patent number: 6964897
    Abstract: A DRAM array in an SOI wafer having a uniform BOX layer extending throughout the array eliminates the collar oxide step in processing; connects the buried plates with an implant that, in turn, is connected to a conductive plug extending through the device layer and the box that is biased at ground; while the pass transistors are planar NFETs having floating bodies that have a leakage discharge path to ground through a grounded bitline.
