Latest Patents
One of his latest patents is titled "Apparatus and method for rounded ONO formation in a flash memory device." This invention describes a method and apparatus for continuously forming a rounded charge trapping layer in a flash memory device. The memory device includes a semiconductor layer with a source/drain region and an adjacent isolation region. A first insulator is placed above the source/drain region, and a charge trapping layer is integrated within the first insulator. This charge trapping layer features a bulk portion along with a first and second tip on either side, extending beyond the width of the source/drain region. Additionally, a second insulator is positioned above the charge trapping layer, topped with a polysilicon gate structure that is wider than the source/drain region.
Another significant patent is "Edge rounded field effect transistors and methods of manufacturing." This technology focuses on gate sidewall engineering of field effect transistors. The techniques involve forming a blocking dielectric region and nitridation of its surface. Following nitridation, a gate region is created, and the sidewalls of the gate region are oxidized to round off sharp corners, thereby reducing the electrical field at the gate corners.
