Patent ID: 7012031

Claim:
A method for fabricating a photoresist pattern, comprising: providing a semiconductor substrate; forming a film of photoresist on the semiconductor substrate; forming main patterns in the photoresist film over a plurality of device-forming regions of the semiconductor substrate, respectively, wherein each of said main patterns defines a series of openings in the photoresist film that expose a layer disposed beneath the film, said openings having a critical dimension, and the device-forming regions being dedicated to accommodate components of at least one semiconductor device; and forming a plurality of test patterns in the film along scribe regions of the semiconductor substrate, the scribe regions extending between the device-forming regions and separating the device-forming regions from one another, the plurality of test patterns each defining at least one opening having a shape similar to that of the openings defined by said main patterns, the at least one opening defined by one of said test patterns having a critical dimension similar to that of the openings defined by said main patterns, and the at least one opening defined by another of said test patterns having a critical dimension different from that of the openings defined by said main patterns.
