Abstract: An illumination source is optimized by changing the intensity and shape of the illumination source to form an image in the image plane that maximizes the minimum ILS at user selected fragmentation points while forcing the intensity at the fragmentation points to be within a small intensity range. An optimum mask may be determined by changing the magnitude and phase of the diffraction orders to form an image in the image plane that maximizes the minimum ILS at user selected fragmentation points while forcing the intensity at the fragmentation points to be within a small intensity range. Primitive rectangles having a size set to a minimum feature size of a mask maker are assigned to the located minimum and maximum transmission areas ad centered at a desired location. The edges of the primitive rectangle are varied to match optimal diffraction orders O(m,n). The optimal CPL mask OCPL(x,y) is then formed.

Abstract: Optimization of illumination for a full-chip layer is disclosed. A pitch frequency of the full-chip layer is determined so as to generate a pitch frequency histogram of the full-chip layer. The pitch frequency indicates how often a given pitch occurs in the full-chip layer. The pitch frequency histogram is equated to be the first eigenfunction from the sum of coherent system representation of a transformation cross coefficient. An integral equation for the first eigenfunction of the transformation cross coefficient is solved so as to define the optimal illumination for imaging the full-chip layer.

Abstract: Model OPC is developed based on eigen decomposition of an aerial image expected to be produced by a mask pattern on a surface of a resist. With the eigen decomposition method the aerial image intensity distribution around a point (x, y) is accurately described in the model. A scalar approach may be used in the eigen decomposition model which treats the light wave through the mask as a scalar quantity. A eigen decomposition alternatively may use a vector approach which utilizes a vector to describe the light wave and the pupil function. A predicted SPIF may be generated from the aerial image which may be used to verify the mask modeling process by comparing the predicted SPIF to an experimentally determined SPIF. The model OPC, once calibrated, may be used to evaluate performance of a mask and refine features of the mask.
