Abstract

A semiconductor device in a first area includes first non-planar semiconductor structures separated with a first distance, and a first isolation region including a first layer and a second layer that collectively embed a lower portion of each of the first non-planar semiconductor structures. At least one of the first layer or second layer of the first isolation region is in a cured state. The semiconductor device in a second area includes second non-planar semiconductor structures separated with a second distance, and a second isolation region including a first layer and a second layer that collectively embed a lower portion of each of the second non-planar semiconductor structures. At least one of the first or second layer of the second isolation region is in a cured state.
