Abstract:
A method for immersion lithography includes providing a substrate coated with an imaging layer, dispensing a conductive immersion fluid between the substrate and an imaging lens of a lithography system, and performing an exposure process to the imaging layer using a radiation energy through the conductive immersion fluid.
Abstract:
An immersion lithography system includes an immersion fluid holder for containing an immersion fluid. The system further includes a stage for positioning a resist-coated semiconductor wafer in the immersion fluid holder and a lens proximate to the immersion fluid holder and positionable for projecting an image through the immersion fluid and onto the resist-coated semiconductor wafer. The immersion fluid holder includes a coating configured to reduce contaminate adhesion from contaminates in the immersion fluid.
Abstract:
Provided are a high resolution lithography system and method. In one example, a method for producing a pattern on a substrate includes separating the pattern into at least a first sub-pattern containing lines oriented in a first direction and a second sub-pattern containing lines oriented in a second direction. Lines oriented in the first direction are created on a first layer of photosensitive material on the substrate using a first standing wave interference pattern. A portion of the created lines are trimmed to create the first sub-pattern. A second layer of photosensitive material is applied to the substrate after creating the first sub-pattern. Lines oriented in the second direction are created on the second layer using a second standing wave interference pattern. A portion of the created lines are trimmed to create the second sub-pattern.
Abstract:
Water-continuous emulsion of curable elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size less than 5 μm, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; a curable elastomeric polymer, surfactant, internal cure additive, water, optional plasticizer, and optional low molecular weight acid. The water-continuous emulsions of curable elastomeric polymers can be prepared by; (I) forming a premix comprising an elastomeric polymer, surfactant, and internal cure additive, and (II) adding water to the premix with mixing to form a water continuous emulsion of the curable elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 μm, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.
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.
