Abstract: A method of manufacture of a mask system includes: providing design data; generating a substantially circular optical proximity correction target from the design data; biasing a segment of the substantially circular optical proximity correction target; and generating mask data based on the shape produced by biasing the segment of the substantially circular optical proximity correction target.

Abstract: An integrated circuit system that includes: providing a substrate coated with a photoresist material; exposing the photoresist material to an energy source through a first mask to form a first substrate feature and a second substrate feature therein; and exposing the photoresist material to the energy source through a second mask to transform the second substrate feature into another one of the first substrate feature therein.

Abstract: Apparatus is provided for determining presence of contamination on a lithography mask, including: a fluid trap having a base and at least one wall member extending substantially perpendicularly to the base for trapping fluid on a portion of the base when fluid introduced during a cleaning process of the mask is removed.

Abstract: A reticle system that includes: providing a reticle system; and assigning two or more of an image pattern onto the reticle system to form one or more layers of an integrated circuit system by grouping and pairing each of the image pattern onto the reticle system according to a multi-layer reticle grouping/pairing flow.

Abstract: The present invention relates to monitoring structures. More particularly, but not exclusively, the invention relates to a monitoring structures suitable for placement on masks. Still more particularly, but not exclusively, the invention relates to monitoring structures suitable for monitoring haze growth on photomasks. Embodiments of the invention provide apparatus for determining presence of contamination on a lithography mask, comprising: a fluid trap, the fluid trap comprising: a base and at least one wall member extending substantially perpendicularly to the base and arranged to trap fluid on a portion of the base when fluid introduced during a cleaning process of the mask is removed.
