Title: Formation of wiring pattern composed of buried metal
Inventor: SASAKI MAKOTO
IPC: H01L21/3205
Filed: 1989-12-28
Abstract: PURPOSE:To form a wiring pattern composed of a buried metal onto a substrate by irradiating a metallic layer for a wiring on the substrate, to which a trench or a hole is formed, with laser beams, flattening a surface and etching the metallic layer for the wiring in the thickness direction. CONSTITUTION:The trench 12 of a specified pattern is formed onto the surface of a substrate 11. When a metallic layer 13 for a wiring consisting of aluminum, etc. is shaped onto the substrate 11 through the method of evaporation, etc., and the surface of the metallic layer 13 is irradiated with laser beams, the surface section of the metallic layer 13 is melted, and the surface is flattened. When the metal of the surface section of the metallic layer 13 is solidified and the metallic layer 13 is etched in the thickness direction, the metallic layer 13 is removed, and a wiring pattern made up of a buried metal 14 is formed onto the substrate 11. Accordingly, a metal for the wiring is buried easily into the trench or a hole formed to the substrate, thus shaping the wiring pattern of the buried metal onto the substrate.

Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To effectively prevent generation of fogging material and ozon by photochemical reactions even when exposure light has a short wavelength. SOLUTION: A gas distribution channel indicated by a dotted arrow is formed in a housing 38 constituting a part of a lighting optical system. The air in the inner space of lens-barrels 68, 70 and 72 is replaced with nitrogen gas through the distribution channel. Nitrogen gas is provided also to the inner space of the housing 38 through a supply opening of an open/close device 92F. Accordingly, the concentration of oxigen in the inner space of the housing 38 and lens-barrels 68, 70 and 72 is kept low and the oxidation reaction during photochemical reactions can be prevented. Since the product (fogging material) generating after the oxidation is inhibited, fogging is prevented.
