Abstract:
A method for manufacturing a semiconductor device which includes fine patterns having various critical dimensions (CDs) by adjusting a thickness of spacer used as an etching mask in Spacer Patterning Technology (SPT). The method for manufacturing a semiconductor device includes forming spacers at a different level over an etching target layer and etching the etching target layer exposed among the spacers.
