Patent number: 9859281Abstract: A technique for forming a semiconductor device is provided. Sacrificial mandrels are formed over a hardmask layer on a semiconductor layer. Spacers are formed on sidewalls of the sacrificial mandrels. The sacrificial mandrels are removed to leave the spacers. A masking process leaves exposed a first set of spacers with a second set protected. In response to the masking process, a first fin etch process forms a first set of fins in the semiconductor layer via first set of spacers. The first set of fins has a vertical sidewall profile. Another masking process leaves exposed the second set of spacers with the first set of spacers and the first set of fins protected. In response to the other masking process, a second fin etch process forms a second set of fins in semiconductor layer using the second set of spacers. The second set of fins has a trapezoidal sidewall profile.Type: GrantFiled: July 26, 2016Date of Patent: January 2, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chia-Yu Chen, Zuoguang Liu, Miaomiao Wang, Tenko Yamashita
