Abstract: PURPOSE:To produce a high-strength hot-rolled steel plate excellent in fatigue characteristic and workability by subjecting a slab of a low alloy steel with specific composition to hot rolling, cooling, and coiling under respectively specified temp. conditions. CONSTITUTION:A slab of a steel which has a composition containing, by weight, 0.07-0.2% C, 1.5-2.5% Si, 1.2-2.5% Mn, 0.5-1.5% Cr, 0.1-1.5% Cu, 0.1-1.5% Ni, <=0.03% P, <=0.005% S, and 0.01-0.06% Al or further containing <=0.01% Ca is hot-rolled. After hot rolling is finished at a temp. not lower than the Ar3 point, the resulting plate is slowly cooled down to a two phase region between the Ar3 point and the Ar1 point at (3 to 20) deg.C/sec cooling rate or cooled down to the two phase region between the Ar3 point and the Ar1 point at >=30 deg.C/sec cooling rate and slowly cooled for 2-20sec at (3 to 20) deg.C/sec cooling rate, followed by coiling at a temp. between 550 deg.C and the Ms point.

Title: Preparation of liquid cleaning agent and semiconductor device
Inventor: KATO NOBUHIRO
IPC: H01L21/304
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a liquid cleaning agent which exerts a high metal-removing effect and reduces the cost burden. SOLUTION: A liquid prepared by adding a chelating agent to an aqueous solution containing citric acid is used as a base-cleaning agent. A high metal- removing effect is obtained by a synergistic effect between citric acid and a chelating agent. Therefore, a cleaning agent prepared by adding a small amount of chelating agent to a low-concentration aqueous solution of citric acid yields an equal or higher metal- or metal compound-removing effect compared to conventional cleaning agents. Especially, the synergistic effect is exerted eminently when the chelating agent is ethylidene diphosphonic acid, methylene phosphonic acid or methyl diphosphonic acid.  In a base-cleaning process carried out after the CMP(chemical-mechanical polishing) process in the preparation process of a semiconductor device, base is cleaned using the cleaning agent to effectively remove abrasive grains, abrasive liquid and abraded materials residing on the base surface.
