A disadvantage of wet etching is the undercutting caused by the isotropy of the etch. The purpose of dry etching is to create an anisotropic etch - meaning that the etch is uni-directional. An anisotropic etch is critical for high-fidelity pattern transfer. RIE etching is one method of dry etching.
