摘要:
A utility bucket backpack apparatus having an upper strap and a lower strap may have each of the upper and lower straps connected to two backpack straps. The lower strap may further be connected to a bottom strap. The upper strap may further be connected to two handle straps. The upper strap and the lower strap may also be removably connected to the outer circumference of a utility bucket.

The present invention is a method and apparatus for applying proximity correction to a piece of a mask pattern, by segmenting the piece into a plurality of segments, and applying proximity correction to a first segment without taking into consideration the other segments of the piece.
摘要:
A method is disclosed for identifying regions of an integrated circuit layout design where optical proximity correction will be most useful and then performing optical proximity correction on those regions only. More specifically, the method includes the following steps: (a) analyzing an integrated circuit layout design with a design role checker to locate features of the integrated circuit layout design meeting predefined criteria; and (b) performing optical proximity correction on the features meeting the criteria in order to generate a reticle design. The criteria employed by the design role checker to select features include outside corners on patterns, inside corners on features, feature size, feature shape, and feature angles.
