Fine featured photo-resist artwork design for chemical milling

摘要

The invention is a method of forming the art work for chemically etching that produces uniform through-etch and lateral-etch. The artwork that defines the pattern to be etched utilizes lines equal to the narrowest feature that is to be etched. Rather than etch away large areas, section are removed by etching by cutting them out of the material that is being etched. The artwork or pattern is designed with the same compensation factors throughout the entire pattern and the etch rate will be completely uniform for the entire pattern.
