| Résumé |
|
For sub-10nm technologies, the semiconductor industry is facing the limits of conventional lithography to achieve narrow dimensions. DSA (Directed Self-Assembly) of Block Copolymers (BCP) is one of the most promising solutions to reach sub-10nm patterns with a high density. One challenge for DSA integration is the removal of PMMA selectively to PS. In this paper, we propose to study PMMA removal selectively to PS by screening different plasma etch chemistries. These chemistries developed on blanket wafers have been tested on cylindrical and lamellar patterned wafers.
