Title: Etching method of semiconductor layer
Inventor: KUNIHARA KENJI
IPC: H01L21/306
Filed: 1986-09-02
Abstract: PURPOSE:To etch only an Al x Ca(1-x)As mixed crystal layer and not to etch a GaAs layer, by using an aqueous solution of a hydrofluoric acid. CONSTITUTION:An Alx Ga(1-x)As mixed crystal is made to grow on a GaAs substrate crystal, with the molar fraction (x) of aluminum varied with in a range from x = 0 to x = 0.4, and each crystal is made to react with a water solution of a hydrofluoric acid which is adjusted to have a prescribed concentra tion and a liquid temperature of 26 deg.C. The practical concentration of the aque ous solution of the hydrofluoric acid is 10 wt.% to 40 wt.% and the optimum concentration 15 wt.% to 35 wt.%. The operating temperature of the aqueous solution of the hydrofluoric acid is 10 deg.C to 35 deg.C practically. As a result, only an Alx Ga(1-x)As mixed crystal layer of a hetero junction substance formed of the Alx Ga(1-x)As mixed crystal layer and a GaAs crystal layer is etched selectively, so that a hetero interface may be exposed exactly and with excellent reproducibility. This facilitates fine processing of a hetero junction and, concequently, enables the stable manufacture of an element having the hetero junction of the Alx Ga(1-x)As mixed crystal layer and the GaAs crystal layer.

Then the liq. containing the powder in a tank 2 is suck to the syringe when the piston moves upward, and the liq. is applied on a surface to be coated when the piston moves downward thereafter. In such a case, the syringe 20 having the volume at least 2 times that of the liq. to be suck is used and the syringe is formed in a two-body structure divided at almost central part of the up-down direction. Then the liq. incorporated with the powder is housed in an under syringe 8 by sucking.

Title: Brazing sheet for fin
Inventor: YAMAGUCHI MOTOYOSHI
IPC: C22C21/02
Filed: 1987-08-20
Abstract: PURPOSE:To improve corrosion resistance and brazing characteristic and also to prevent the occurrence of white powder due to corrosion, by forming an outer shell of a core material made of Al material by using Al containing specific amounts of Si and Cu. CONSTITUTION:This brazing sheet for fin consists of a core material made of Al or Al alloy and a skin material which has a composition consisting of, by weight, 6-15% Si, 0.1-2% Cu, and the balance Al and containing, if necessary, 0.1-2% Mn and/or 0.5-2% Mg. In the skin material of this sheet, when Si content is outside the above range, the melting point is raised and brazing becomes difficult. Cu and Mn have corrosion resistance-improving effect, respectively, but this effect is reduced when their contents are below 0.1%, and, when they exceed 2%, brazing characteristic is deteriorated. Further, Mg has a function of enabling brazing by breaking an oxide film formed on a material surface, and, when its content is below 0.5% the above effect is insufficient, while workability is deteriorated when it exceeds 2%.
