Latest Patents

One of her latest patents is titled "Method for fabricating interpoly dielectrics in non-volatile stacked-gate memory structures." This innovative method involves forming an improved interpoly oxide-nitride-oxide (ONO) structure in stacked gate memory cells. The process utilizes Low Pressure Chemical Vapor Deposition (LPCVD) of tetraethylorthosilicate (TEOS) to create a robust top oxide layer, which minimizes degradation of the tunnel oxide and enhances memory cell performance. Additionally, steam densification of the TEOS layer significantly reduces erosion during subsequent processing steps, leading to a more reliable ONO structure with lower leakage current.

Another notable patent is the "Method and apparatus for pre-conditioning flash memory devices." This invention addresses erase-induced stress within flash memory devices by subjecting the memory cells to a short write process before erasing. This pre-conditioning method is applied to an entire sector at once, ensuring optimal performance and longevity of the flash memory cells.
