Method of manufacturing semiconductor device, mask and semiconductor device

摘要

A method of manufacturing a semiconductor device answerable to refinement of circuits by correctly connecting adjacent small patterns with each other with excellent reproducibility in connective exposure and a semiconductor device manufactured by this method are proposed. According to this method of manufacturing a semiconductor device, connective exposure is performed by dividing a pattern formed on a semiconductor substrate into a plurality of patterns and exposing the plurality of divided patterns in a connective manner, by forming marks for adjusting arrangement of the patterns to be connected with each other on the semiconductor substrate before exposing patterns of a semiconductor element and connectively exposing the patterns of the semiconductor element in coincidence with the marks for adjusting arrangement.
