Abstract:
Methods of forming and processing semiconductor devices which utilize a three-color process are described. Certain embodiments relate to the formation of self-aligned contacts for metal gate applications. More particularly, certain embodiments relate to the formation of self-aligned gate contacts utilizing the formation of self-aligned growth pillars. The pillars lead to taller gate heights and increased margins against shorting defects.
