    摘要: A dual wavelength exposure system provides for patterning a resist layer formed on a wafer for forming semiconductor devices, using two exposure operations, one including a first radiation having a first wavelength and the other including a second radiation including a second wavelength. Different or the same lithography tool may be used to generate the first and second radiation. For each die formed on the semiconductor device, a critical portion of the pattern is exposed using a first exposure operation that uses a first radiation with a first wavelength and a non-critical portion of the pattern is exposed using a second exposure operation utilizing the second radiation at a second wavelength. The resist material is chosen to be sensitive to both the first radiation having a first wavelength and the second radiation having the second wavelength.

    摘要: A lithography apparatus includes at least two reticle edge masking assemblies (REMAs). The lithography apparatus further includes a light source configured to emit a light beam having a wavelength and a beam separating element configured to divide the light beam into more than one collimated light beam. Each REMA is positioned to receive one of the more than one collimating light beams and each REMA comprises a movable slit for passing the one collimated light beam therethrough. The lithography apparatus further includes at least one mask having a pattern, where the at least one mask is configured to receive light from at least one of the REMA and a projection lens configured to receive light from the at least one mask. A method of using a lithography apparatus is also discussed.
