发明名称 FINFET AND METHOD FOR MANUFACTURING THE SAME
摘要 A FinFET and a method for manufacturing the same are disclosed. In one aspect, the method comprises forming a semiconductor fin having trapezoid cross-section. The method also includes forming one of a source region and a drain region. The method also includes forming a sacrificial spacer. The method also includes forming another one of the source region and the drain region using the sacrificial spacer as a mask. The method also includes removing the sacrificial spacer. The method also includes forming a gate stack in place of the sacrificial spacer, the gate stack comprising a gate conductor and a gate dielectric isolating the gate conductor from the semiconductor fin.
