Photomask quality requirements for lithography
(1) The graphic size is accurate, in line with the design requirements, and no distortion occurs.
(2) There should be a certain number of exactly the same graphics, and each version of the mask plate should be able to be fitted one by one, and the fitting error should be as small as possible.
(3) The contrast between the black and white domains of the graphics should be high, and the general requirements are above 2.5.
(4) The graphic edge should be smooth, no burr, and the transition zone should be small (that is, the "black zone" should be as steep as possible to the "transparent zone").
(5) The layout is smooth, smooth, no pinholes, scratches and islands.
(6) The layout is strong and durable, not easy to deformation.
