Prior to applying the SDR, a wet cleaning step is performed to remove organic contaminants that may have deposited during shipping and storage and could (loc lly) mask or retard the SDR process. An alkaline mixture is usually used to lessen further damage to the silicon, in which case the surface
Dry etching is predominantly anisotropic. Reactive ion etching is used to edge isolate. During wet etching processes, the solid is immersed in a chemical solution (which can be either acidic or alkaline) and material is removed by dissolution.
