Dry Etching - MIT OpenCourseWare

Dry Etching. We covered wet etching. which is essentially chemical and isotropic. (because it is chemical, it is highly selective) Now we consider dry etching (which has largely replaced wet) based on highly anisotropic sputtering process. and may include reactive ions, so can also be chemical and selective.
