MEMS lithography mask with improved tungsten deposition topography and method for the same
Abstract:
The present invention discloses a MEMS lithography mask with improved tungsten deposition topography and a method for making the same. The MEMS lithography mask includes: a pattern including at least two sections forming a conjunction with each other, each of the at least two sections having a width not less than a minimum width, the conjunction having a center and a plurality of corners, wherein at least one of the corners is inwardly recessed to reduce a width of the conjunction, the sections being for defining trenches on a substrate to be filled with tungsten as apart of a MEMS device, whereby the lowest height of the tungsten surface is not lower than 80% of the trench height.
