Title: The Innovations of Jeffrey P. Kasold

Introduction

Jeffrey P. Kasold is a notable inventor based in San Jose, California. He has made significant contributions to the field of non-volatile memory technology and IGFET devices. With a total of 2 patents, his work has had a lasting impact on the industry.

Latest Patents

One of his latest patents is for a Gate EEPROM cell. This innovative non-volatile memory cell utilizes two different areas for electron injection, allowing for direct overwriting of previously stored data without the need for an intervening erase cycle. The design features a floating gate FET with dual programming gates on its floating gate. Each programming gate includes a layer of dual electron injector structure (DEIS) and a polysilicon electrode. When writing a '0', one programming gate removes charge from the floating gate, while the other programming gate injects charge into the floating gate when writing a '1'. Notably, this charge transfer does not occur if the previously stored logic gate and the logic state to be written are identical.

Another significant patent involves a method for forming IGFET devices with improved drain voltage. This method provides less than one micron p-n junction regions for IGFET devices by implanting a high concentration of arsenic near the surface of a semiconductor substrate. Phosphorus is also implanted with an energy that ensures its maximum concentration is below that of the arsenic and at least one order of magnitude less. An oxidation/anneal step thermally diffuses the implanted ions to create a junction less than one micron in thickness.
