摘要:
A method and apparatus for locally etching a substrate area the method including providing a substrate comprising a process surface; depositing a material layer over the process surface; and, applying a wet etchant to cover a targeted etching portion of the process surface while excluding an adjacent surrounding area to selectively etch the material layer overlying the targeted etching portion.

摘要:
The invention involves a system and a method of inspecting a selected part design from an inventory of computer-aided part designs for die compliance as to the part design's geometric characteristics of die lock, draft, and sharp edge. The invention provides for an improvement of inspecting a computer-aided part design in order to lessen insufficient inspections which lead to manufacturing infeasibilities. The invention includes selecting a part design, defining a die open direction, evaluating die lock and draft characteristics of the selected part design, and evaluating sharp edge characteristics of the selected part design.
