Abstract :
Stencil mask implantation technology was applied to Damascene metal gate MOSFET fabrication process. p-MOSFET can be successfully fabricated by using phosphorous channel implants with improved stencil masks. The threshold voltage values can be controlled by implanted dose as well as conventional implants. The present technology is effective in reducing raw process time, equipment cost and clean room space.
