    摘要: Disclosed is a photomask having a wavelength-reducing material that may be used during photolithographic processing. In one example, the photomask includes a transparent substrate, an absorption layer having at least one opening, and a layer of wavelength-reducing material (WRM) placed into the opening. The thickness of the WRM may range from approximately a thickness of the absorption layer to approximately ten times the wavelength of light used during the photolithographic processing. In another example, the photomask includes at least one antireflection coating (ARC) layer.

    摘要: An immersion lithography system for semiconductor manufacturing provides a lens assembly that moves relative to a wafer surface and includes a nozzle and drain assembly that is coupled to, and moves along, the lens assembly. The nozzle and drain assemblies may be disposed circumferentially opposite each other about the lens or an annular ring may be provided that surrounds the lens and includes a plurality of selectable alternating nozzles and drains. The nozzle and drain assemblies may rotatably surround the lens. At least a portion of the wafer being patterned is immersed in a liquid provided by the nozzle assembly and a flow direction is controlled by manipulating the nozzle and drain assemblies. Flow direction may be advantageously directed outwardly to reduce particulate contamination.

    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 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.
