SUMMARY
The discussion centers on the anisotropic etching of (110) silicon wafers, specifically addressing why these wafers form perpendicular trenches with the (111) orientation. It is established that when etching is anisotropic, the walls of the etched features are perpendicular to the wafer surface, leading to the formation of distinct trench geometries. This behavior is critical for applications in semiconductor manufacturing and microfabrication processes.
