His work focuses on enhancing the manufacturing processes of memory cells and polysilicon structures, which are crucial for modern electronic devices.
Latest Patents
One of his latest patents is titled "Enhance the process window of memory cell line/space dense pattern in sub-wavelength process." This invention provides a new method for creating densely patterned interconnect lines. The first step involves modifying the mask layout to sharply decrease the ratio of line width (L) to line spacing (S). The resulting line pattern reflects this reduction, and the width of the created lines is increased through thermal flow while concurrently decreasing the spacing between the lines.
Another notable patent is the "Process to define N/PMOS poly patterns." This method fabricates doped polysilicon structures by first providing a substrate and forming an undoped polysilicon layer over it. The layer is then patterned to create undoped polysilicon structures in both N and P areas. The process includes doping steps to complete the fabrication of the doped polysilicon structures, which are essential for various electronic applications.
