HIGH-DENSITY MASK FOR THREE-DIMENSIONAL SUBSTRATES AND METHODS FOR MAKING THE SAME

摘要

A method for fabricating high-density masks for non-planar or three-dimen-sionail substrates utilizes a mandrel having one or more precision forms machined therein. Once the mandrel with one or more forms is fabricated, one or more mask blanks may be constructed thereon. The final masks may be cut from one or more mask blanks. C))
