Abstract: PROBLEM TO BE SOLVED: To realize a wiring structure having a fine connecting hole without affecting a transistor or the like, by forming the connecting hole so as to penetrate a wiring layer, making a lower wiring layer into a laminated structure of a high-melting point metal, Al alloy in which Al is main component, etc., and forming the connecting hole so as to reach the high-melting point metal. SOLUTION: In a first layer 301 of a first wiring layer formed of high-melting point metal or the like, TiN is formed by a sputtering method. A second layer 302 constituting the first wiring layer is deposited on the first layer 301 by a sputtering method of Al alloy. After that, a wiring pattern is formed, and a wiring is formed by etching. A connecting hole pattern is formed by using a photomask using the first wiring layer as the reference, and a connecting hole 304 is formed by dry etching. At this time, after the connecting hole has reached the first wiring layer, etching gas is switched, the second layer 302 in which Al is main component from among the first wiring layer, is etched completely, and the first layer 301 is left. After that, a second wiring layer 305 composed of Ti/TiN is deposited.

Title: Formable prepreg
Inventor: FUJII SADAO
IPC: B29K101/10
Filed: 1990-10-19
Abstract: PURPOSE:To obtain prepreg, which is excellent in handleability and formability and out of which a formed article having excellent rigidity and strength is obtained, by a method wherein reinforcing material is impregnated with composition mainly consisting of solid thermosetting resin, liquid electron radiation curing unsaturated group-containing compound, which is incompatible with said resin, and solvent and, after the removal of the solvent, electron rays are irradiated over the resultant material. CONSTITUTION:The optimum solid thermosetting resin is phenolic resin. If the liquid unsaturated group-containing compound is compatible with said thermosetting resin, surface tackiness remains after the irradiation of electron rays, resulting in lowering handleability. As the unsaturated compound used, various acrylates, vinyl compounds and the like are exampled. The elongation of the matter cured by irradiating electron rays over single compound is preferably 20% or more. The preferable ratio of the thermosetting resin to the unsaturated group-containing compound is 40/60-90/10. As the solvent, one which dissolves both the thermosetting resin and the unsaturated group-containing compound, is selected. In addition, solvent, which is incompatible with the thermosetting resin and has the boiling point higher than that of the solvent just mentioned above, is preferably added as main component. Further, the addition of blowing agent may also be possible.
