WebProjection Optical Lithography. Projection optical lithography offers highest resolution (less then 0.35pm) than proximity and contact printing. Projection printing relies on an image formation system between the mask and the resist because the beam is focused between the mask and the resist wafer. The complete process is illustrated in figure 4.4. WebOptical Lithography Models in ATHENA Introduction ATHENA’s Optolith module is designed to simulate the 3 basic lithography technologies; contact printing, proximity and projection lithography. The imaging calculations within Optolith are flexible enough to handle all three situations.
