发明名称 Method for making a doped well in a semiconductor substrate
摘要 A method for making a dopant well in a semiconductor substrate, wherein a dopant is implanted directly into an exposed surface of a semiconductor substrate through an opening in a dopant-absorbing coating and the substrate is heated to drive the implanted dopant further into the substrate. The method requires fewer steps than the conventional method, and is particularly applicable in the fabrication of CMOS devices.
