Dry etch processes use plasma and gases to etch materials with high precision, suitable for complex patterns. Wet etch involves chemical solutions that remove material more simply but with less control. Both are essential in semiconductor manufacturing, but dry etch offers better anisotropy and control, while wet etch is faster and more cost-effective for certain applications.
