IPC: H01L21/3205
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce friction between a wiring formation layer and a substrate and hence bury the wiring formation layer in the interior of a connection hole by forming a substrate lubricating layer comprising a metal material having a lower melting point than a reflow temperature of the wiring formation layer on a side wall upper part of the connection hole and on a substrate layer around the side wall upper part to melt the substrate lubricating layer upon reflowing. SOLUTION: A substrate layer 12 is formed on a substrate 11, and a connection hole 13 is formed in the substrate layer 12. There is formed a substrate lubricating layer 14 is formed on an upper side part of the connection hole 13 and on the substrate layer 12, the substrate lubricating layer 14 comprising a metal material having a lower melting point than a reflow temperature of a wiring formation layer 15. Thereafter, the wiring formation layer 15 is formed on the substrate layer 12 so as to cover the upper portion of the connection hole 13. Hereby, the substrate lubricating layer 14 is melted upon reflowing so that there is reduced friction between the wiring formation layer 15 and the substrate layer 12. For this, the wiring formation layer 15 is facilitated to enter the connection hole 13. Thus, the wiring formation layer 15 can be buried in the connection hole very easily and satisfactorily.

Title: Production of activated carbon with high specific surface area from bean curd lee
Inventor: MUROYAMA KATSUHIKO
IPC: C10L5/44
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To produce an activated carbon with a high specific surface area from bean curd lees. SOLUTION: Bean curd lees are impregnated with an equal amt. of an alkali metal compd. (e.g. potassium carbonate, sodium carbonate, or sodium hydroxide), carbonized and activated in a nitrogen atmosphere, and washed, thus giving an activated carbon with a specific surface area greatly larger than that of a commercially available activated carbon. Since this method enables a considerable reduction in the amt. of the alkali metal compd. used for impregnation and facilitates the recovery of the compd., advantageous effects are achieved in terms of cost and apparatus corrosion.
