Webbetween the mask and wafer (typically 10 μm to 50 μm) introduces optical diffraction at the feature edges on the photomasks and the resolution is typically degraded to the 2 to 5 μm regime. Figure 5.4: (a) Contact printing. (b) Proximity printing. The minimum line-width that can be printed, l m, in shadow printing is roughly given by: l m
