Title: Lithographic process
Inventor: OMI TADAHIRO
IPC: G03F7/32
Filed: 1992-08-07
Abstract: PURPOSE:To enable the formation of ultrafine resist patterns having different sizes and shapes in a designed manner by using a developer contg. a surfactant having the ability to increase the dissolution of small resist patterns. CONSTITUTION:A resist is exposed to prescribed patterns by a deformation illumination method at the time of forming the resist patterns. The developer having the ability to increase the dissolution of the resist which is small in the resist regions to be dissolved away of the formed resist layer is used. The surfactant is an amine surfactant having a defoaming property and an ethylene/ propyl block in a branch chain group and has an amine group, ethylene oxide group and propyl oxide group as a hydrophilic group. Then, the surfactant exists in the fine areas where liquid is hardly penetratable if the resist is developed by using this developer and, therefore, the development progresses by way of the process similar to the process for the large pattern areas and the patterns are formed regardless of the sizes and shapes.

Abstract: PROBLEM TO BE SOLVED: To suppress the generation of blowholes and pits in a steel sheet and to impart excellent arc weldability thereto by applying the surface of a plated steel sheet coated with a specified amt. of galvanizing with a specified amt. of zinc phosphate film. SOLUTION: The surface of a steel sheet 1 is plated with galvanizing so as to control the coating weight per side to 15 to 80 g/m2.
