Latest Patents

One of his latest patents is titled "Split gate embedded flash memory and method for forming the same." This invention provides a split-gate embedded flash memory cell that includes split-gate transistors. The control gate is aligned with respect to the floating gate without the need for a photolithographic patterning operation. An anisotropic blanket etching operation is utilized to form the floating gates alongside the sidewalls of a sacrificial layer. This method eliminates the need for local oxidation of silicon (LOCOS) methods, thereby maintaining high integrity for the floating transistor gates. The floating gates are formed from charge storage materials such as silicon nitride in some embodiments.

Another significant patent involves nitride shallow trench isolation (STI) structures. This shallow trench isolation structure features a top surface made entirely of silicon nitride. The top surface of the STI structure is either coplanar with or extends above the top substrate surface. The STI structures also include additional dielectric materials beneath the silicon nitride and an oxide liner, ensuring robust performance.
