    Abstract: A method of producing defect free resist images from defective phase shifting or extreme ultraviolet masks is described. The method uses supplemental radiation to achieve direct repair of the resist image. Pinhole type of defects in opaque pattern elements, which would cause overexposed regions of resist and can readily be repaired on the mask, are first repaired directly on the mask before the mask is used in the exposure of a layer of resist. The remaining defects on the mask are left as they are and not repaired. The layer of resist is then exposed using the partially repaired mask. The remaining mask defects will cause unexposed latent images in the layer of resist. These unexposed regions of the resist are then exposed using supplemental radiation thereby correcting the exposure of the layer of resist. The layer of resist is then developed to form a defect free resist image.

    Abstract: For lithographically producing the smallest structures at less than the exposure wavelengths in semiconductor fabrication, a double exposure is carried out using a thick phase mask and a trimming mask, the trimming mask further structures the phase-contrast lines produced by the phase mask. Besides transparent or opaque regions, the trimming mask also has phase-shifting regions. These surround transparent regions of the trimming mask through which the phase-contrast lines produced by the first mask are locally re-exposed, that is to say interrupted. The intensity profile of successive line sections is especially rich in contrast through the addition of the phase-shifting partially transparent regions on the second mask; the distances between the line sections can be reduced. The trimming mask, otherwise used only for larger structures, is therefore suitable for the configuration of the finest dimensionally critical structures.
