摘要： When a base film of a substrate is formed, for instance, on a scribe line of a wafer, a quadrangular first inspection pattern is formed in advance, and when a resist pattern is formed, a second inspection pattern are formed so as to be on a straight line to the first inspection pattern in a top plan view. When light is irradiated to a region including the first inspection pattern and the second inspection pattern and a spectrum is formed based on the reflected diffracted light, information of a line width of the second inspection pattern and a pitch of both inspection patterns is contained therein. In this connection, by preparing in advance a group of spectra based on various kinds of inspection patterns according to simulation and by comparing with an actual spectrum, the most approximate spectrum is selected, and thereby the line width and the pitch are estimated to evaluate the resist pattern.

摘要： A resist pattern forming method using a coating and developing apparatus and an aligner being connected thereto which are controlled to form a resist film on a surface of a substrate with a base film and a base pattern formed thereon, followed by inspecting at least one of a plurality of measurement items selected from: reflection ratio and film thickness of the base film and the resist film, line width after a development, an accuracy that the base pattern matches with a resist pattern, a defect on the surface after the development, etc. A parameter subject to amendment is selected based on corresponding data of each measurement item, such as the film thickness of the resist and the line width after the development, and amendment of the parameter is performed. This results in a reduced workload of an operator, and the appropriate amendment can be performed.
