    摘要: Provided is an alignment mark having a plurality of sub-resolution elements. The sub-resolution elements each have a dimension that is less than a minimum resolution that can be detected by an alignment signal used in an alignment process. Also provided is a semiconductor wafer having first, second, and third patterns formed thereon. The first and second patterns extend in a first direction, and the third pattern extend in a second direction perpendicular to the first direction. The second pattern is separated from the first pattern by a first distance measured in the second direction. The third pattern is separated from the first pattern by a second distance measured in the first direction. The third pattern is separated from the second pattern by a third distance measured in the first direction. The first distance is approximately equal to the third distance. The second distance is less than twice the first distance.

    摘要: An apparatus for immersion lithography that includes an imaging lens which has a front surface, a fluid-containing wafer stage for supporting 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 the fluid 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.
