Abstract

See full text

Parallel surfaces on two substrates are established with specific distances of separation, typically within a 10-micron tolerance. In general, one surface is a surface of a transparent membrane or hard window. On one embodiment, the gap defined by the distance of the transparent membrane or hard window and the other surface used to precisely control the dimensions of layers in projection micro stereolithography, however the methods for establishing the relative positions of two surfaces can be adapted to other applications.
