    Abstract: 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.

    Abstract: The present disclosure provides a mask-pellicle system for lithography patterning. The mask-pellicle system includes a mask substrate; a predefined pattern formed on the transparent pattern; a pellicle configured approximate the transparent substrate; a pellicle frame designed to secure the pellicle; and a stress-absorbing feature configured between the pellicle frame and the mask substrate, to reduce stress of the mask substrate.

    Abstract: 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.

    Abstract: An apparatus for immersion lithography that includes an imaging lens which has a front surface, a wafer that has a top surface to be exposed positioned spaced-apart and juxtaposed to the front surface of the imaging lens, and a fluid that has a refractive index between about 1.0 and about 2.0 filling a gap formed in-between the front surface of the imaging lens and the top surface of the wafer. A method for immersion lithography can be carried out by flowing a fluid through a gap formed in-between the front surface of an imaging lens and a top surface of a wafer. The flow rate and temperature of the fluid can be controlled while particulate contaminants are filtered out by a filtering device.
