Latest Patents

Ching-Pen Yeh holds a patent for a "Method of fabricating a semiconductor memory device," specifically focusing on mask ROM technology. This method involves forming a sacrificial oxide layer on a silicon substrate, followed by the application of a photoresist layer. The photoresist layer is then patterned to create openings for bit lines. Arsenic and boron ions are implanted into the silicon substrate through these openings, with the boron ions reaching a greater depth. After implantation, the photoresist and sacrificial oxide layers are removed, allowing for the growth of gate and field oxides on the respective regions of the semiconductor layers. This innovative method has the potential to improve the performance of semiconductor memory devices.
