WebApr 11, 2024 · The 1:1 line-space image is assumed to be defined by just the 0th and 1st orders. For a 180 degree phase shift, there is no change of position, but for phase shifts that depart from 180 degrees, toward 90 degrees, the image begins to shift. Beyond 90 degrees, it starts shifting back, until it reaches the original position at 0 degrees. Figure 2. Web(050.5080) Phase shift. ... Finally, in the event that four-phase masks are difficult to fabricate, but the goal is to still synthesize masks with arbitrary geometry, a third contribution of the paper is the develop-ment of a double-exposure PSM optimization method, where ateach stage the PSM masks are ...
