A disadvantage of wet etching is the undercutting caused by the isotropy–lateral etching at the same rate as the vertical etch. The purpose of dry etching is to create an anisotropic etch – meaning that the etch is directional. An anisotropic etch is critical for good pattern transfer.

WebOct 25, 1999 · A reaction mechanism is proposed for the dissolution process of silicon dioxide networks in aqueous HF-based solutions. Etch experiments with thermally grown silicon dioxide were used to create a model for the etch process. Literature data on the etching of other vitreous silicon dioxide materials were used to refine the model. A new … WebTable 1 shows a summary of the damage probabilities of the two sets of combined etched samples, as well as that of the unetched sample.
