Title: Manufacture of printed wiring board
Inventor: KAWAI MASAYUKI
IPC: H05K3/42
Filed: 1989-09-22
Abstract: PURPOSE:To enable plating only in a through-hole part and to improve etching accuracy by restraining dispersion in thickness of metal foil by boring a through- hole after laminating anti-plating resist film on a surface of metallic foil and thereafter by carrying out through-hole plating. CONSTITUTION:An anti-plating resist film 3 is laminated on a surface of an outermost layer metallic foil 2 of a printed wiring board lamination board 1. After a layer of peeling resist 4 is formed as required, a through-hole 5 is bored. Then, it is immersed in salt solution having plating catalysis; a catalyst layer 6 is formed in a part of the through-hole 5; the layer of the peeling resist 4 is peeled to allow the catalyst layer 6 to remain only inside the through-hole 5; catalyst in only a cross section part of the metallic foil 2 is removed by soft etching; and electrolytic plating is carried out to form a plating layer 7 inside the through-hole 5 alone. After plating treatment, the layer of the antiplating resist film 3 is peeled to expose the metallic foil 2.

Title: Manufacture of semiconductor
Inventor: KURODA TAKARO
IPC: H01S5/00
Filed: 1985-11-06
Abstract: PURPOSE:To enable alignment with a laser and the element structure of a FET by selectively growing a semiconductor having a different composition to a thin section and forming quantum well fine wire structure through buried growth. CONSTITUTION:A periodic groove in width W<=5,000Angstrom  and depth d>=500Angstrom  is prepared onto InP, amorphous regions in both width and depth of 300Angstrom  or less are shaped to the bottoms of the groove pattern, and amorphous sections are removed selectively by a 50%HF liquid. A substrate temperature is elevated to 600-620 deg.C, and the quantities of the gases of In, Ga, As and P fed and molecular-beam dose are reduced extremely and a semiconductor is grown slowly. When a growth rate is extremely slow, the semiconductor does not grow in projecting sections and preferentially grows from the bottoms of recessed sections because chemical potential differences differ in the projecting sections and the recessed sections, thus resulting in selective growth only in the groove sections in -300Angstrom . Accordingly, depth and width in -300Angstrom  or less are obtained with sufficiently excellent reproducibility when the shape of ion beams is controlled, and the semiconductor is fitted to application to a semiconductor laser and a FET.
