DEVELOPMENT METHOD, DEVELOPMENT DEVICE, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/187951
Kind Code:
A1
Abstract:
[Problem] To provide a technology for suppressing post-development line width unsteadiness during development of an exposed wafer using a developer.
[Solution] A negative-type developer D is supplied to a wafer W that has been subjected to an exposure process, and a development process is performed. Then, after drying by rotating the wafer W to drain the developer D on the surface, or after pure water P is supplied to the surface of the wafer W and the pure water P replaces the developer D as a liquid residue on the surface of the wafer W, a rinse fluid R is supplied to clean the surface of the wafer W. Accordingly, the developer D and the rinse fluid R do not become mixed, thus suppressing the dissolution, by the mixed solution of the developer D and the rinse fluid R, of a portion of a resist film that has been made insoluble by the exposure. Thus, the unsteadiness in the line width of a circuit pattern formed on the wafer W can be suppressed.
