    摘要: A method of via patterning mask assignment for a via layer using double patterning technology, the method includes determining, using a processor, if a via of the via layer intercepts an underlying or overlaying metal structure assigned to a first metal mask. If the via intercepts the metal structure assigned to the first metal mask, assigning the via to a first via mask, wherein the first via mask aligns with the first metal mask. Otherwise, assigning the via to a second via mask, wherein the second via mask aligns with a second metal mask different from the first metal mask.

    摘要: The embodiments of via mask splitting methods for double patterning technology described enable via patterning to align to a metal layer underneath or overlying to reduce overlay error and to increase via landing. If adjacent vias violate the G0-mask-split-rule for space or pitch (or both) between vias, the mask assignment of end vias are given higher priority to ensure good landing of end vias, since they are at higher risk of mislanding. The metal correlated via mask splitting methods enable better via performance, such as lower via resistance, and higher via yield.

    摘要: A lithography process to pattern a plurality of fields on a substrate is disclosed. The process includes scanning a first field along a first direction using a radiation beam. Thereafter, the processes steps to a second field adjacent the first field and located behind the first field when the first and second fields are viewed along the first direction. The second field is then scanned along the first direction using the radiation beam.

    摘要: Disclosed is an objective lens adapted for use in liquid immersion photolithography and a method for making such a lens. In one example, the objective lens has multiple lens elements, one of which includes a transparent substrate and a layer of protective coating (PC). The PC is formed proximate to the transparent substrate and is positioned between a liquid used during the liquid immersion photolithography and the transparent substrate to protect the transparent substrate from the liquid.
