A conventional photomask is a transparent plate with the same thickness everywhere, parts of which are covered with non-transmitting material in order to create a pattern on the semiconductor wafer when illuminated. In alternating phase-shift masks, certain transmitting regions are made thinner or thicker. That induces a phase-shift in the light traveling through those regio… Weborder to yield precision phase shift structures. Once again, the etched areas introduce a phase shift of 180° relative to the unetched areas, and the resultant optical interference …
