Paper Abstract
Novel photo-lithography is newly proposed named built-in lens mask lithography. The method emulates optical propagation plane in exposure system using binary transmittance and phase mask instead of projection lens. The performance of the built-in lens mask lithography is studied by numerical simulation and experimental study using conventional proximity exposure system. The result shows resolution enhancement in deep focus plane.
