Summary: The accompanying papers "Optical Lithography" and "Characterization of Positive Photoresist" introduce the concepts of modeling using destruction of the photoactive inhibitor compound to describe exposure and a surface-limited removal rate to describe development together with the optical exposure parameters A, B, and C and a rate relationship, R(M), which characterize the photoresist for modeling purposes. This paper applies the model to, the projection exposure environment: exposure and development of photoresist are treated with a simulation model that allows computation of image surface profiles for positive photoresist exposed with a diffraction limited real image.
