RESIST PATTERN, PROCESS FOR INFORMATION THEREOF, AND PROCESS FOR FORMATION OF WIRING PATTERN |
摘要 |
PURPOSE: A process for the formation of wiring pattern is provided to achieve minute wiring pattern having a desiring size, shape and precision as decrease the deformation of wiring pattern by a heat or stress. CONSTITUTION: A process for the formation of wiring pattern, which includes the steps of: exposing a resist through a photomask, the photomask having a pattern whose line width is equal to or less than a resolution limit; and developing the exposed resist to form a resist pattern having groove depressions on the surface thereof, the depressions not reaching the back of the resist pattern. The resist may be a positive resist in which case the resist pattern is formed on an underplate feed film; a plating metal is precipitated on the feed film in a region not covered by the resist pattern; the resist pattern is stripped after the precipitation; and the feed film is selectively removed in a region not covered by the plating metal. Alternatively, the resist may be a negative resist in which case the resist pattern is formed on a substrate; a metallic material is deposited on the resist pattern and the substrate; and the resist is stripped from the substrate to remove the overlying metallic material.
