Etching at Danchip can be done either with wet chemistry or in dry etch equipment. In general wet chemistry etches isotropically in most materials were as dry etch techniques can be optimized to transfer a given mask pattern with vertical sidewalls (anisotropically) to a given substrate. | Etching at Danchip can be done either with wet chemistry or in dry etch equipment.
