Abstract:
The present invention provides a method of forming a doping region. A substrate is provided, and a poly-silicon layer is formed on the substrate. A silicon oxide layer is formed on the poly-silicon layer. An implant process is performed to form a doping region in the poly-silicon layer. The present invention further provides a method for forming a MOS.
