Method for modulating shapes of substrates
摘要:
The present invention is directed to a method for modulating shapes of a substrate, having first and second opposed surfaces. This is achieved by creating a pressure differential between differing regions of the first opposed surface to attenuate structural distortions in the second opposed surface that results from external forces bearing on the substrate.
