摘要:
A method for manufacturing a semiconductor device includes forming a trench defining a plurality of active fins in a substrate, forming a sacrificial layer on the plurality of active fins, forming a sacrificial oxide layer, and removing the sacrificial oxide layer. The forming the sacrificial oxide layer includes heat-treating the sacrificial layer and surfaces of the plurality of active fins.
