Abstract:
A process for forming semiconductor device comprising:forming trenches to define a first component region and a second component region, wherein: the trenches include a first trench and a second trench; and the first component region lies near the first trench; and the second component region lies near the second trench; forming a first liner within the first trench; and forming a second liner within the second trench, wherein the semiconductor device includes a feature selected from a group consisting of: the first liner is significantly thicker than the second liner; and the first component region has a first edge with a first radius of curvature near the first trench, and the second component has a second edge with a second radius of curvature near the second trench, wherein the first radius of curvature is significantly greater than the second radius of curvature.
