Latest Patents

Ying-Cheng Chen holds a patent for a unique read-only memory with a write operation using a mask. This invention involves a manufacturing process where ROMs can be stockpiled after the gates have been formed and the source and drain implants have been made, but before the write operation is performed. The unwritten ROM features an array of enhancement mode FETs connected in a logical NAND configuration, covered by an overlying layer of insulation. During the write operation, the insulation is removed to expose the drain and source regions of the FETs. A conductive layer is then formed over the array, which is selectively etched to create a short circuit element between the drain and source of those FETs designated to store a binary 0, while allowing the FETs intended to store a 1 to remain switchable.
