Method of fabricating a semiconductor layout and a semiconductor structure

Abstract

The present disclosure discloses a method of fabricating a semiconductor layout comprising the following steps. A layout is provided, and the layout includes a plurality of connection patterns. The connection patterns are decomposed to a plurality of first connection patterns and a plurality of second connection patterns alternatively arranged with each other. An optical proximity correction process is performed on the first connection patterns and the second connection patterns to form a plurality of third connection patterns and a plurality of fourth connection patterns, wherein at least a portion of the third connection patterns is overlapped with the fourth connection patterns. The third connection patterns and the fourth connection patterns are outputted to form photomasks. Accordingly, the quality of the photomask may be improved, and the photomask may therefore include more accurate patterns and contours. The present disclosure also provides a method of fabricating a semiconductor structure.
