Abstract:
A film of single crystal copper is manufactured by means of electrodeposition without heat treatment. The grains of the single crystal copper have an average size of at least 10 μm. The electrolytic solution used in the method contains chloride ions, a wetting agent, sulfuric acid, CuSO 4 .5H 2 O and alkanesulfonate sulfide. The ultra-large copper grains of the present invention contain very few impurities and thus possess low resistance, high conductivity, shining appearance and anti-fingerprint property.

Claim (Index 1):
A manufacturing method of ultra-large copper grain without heat treatment, comprising:\n A. providing an electrodeposit equipment which comprises an anode, a cathode, an electrolytic solution, a power unit, a temperature controller and a mixer; wherein the anode and the cathode respectively connect to the power unit and are immersed in the electrolytic solution; the temperature controller contacts with the electrolytic solution to control the electrolytic solution at 25-55\u00b0 C.; the mixer agitates the electrolytic solution; and the electrolytic solution is obtained by mixing and dissolving chloride ions, wetting agent, sulfuric acid, copper sulfate and sulfur-containing compound having the formula (1) together in deionized water,\n R 1 \u2014S\u2014C n H 2n \u2014R 2  \n wherein R 1 \u2550\u2014H, \u2014S\u2014C n H 2n \u2014R 2  or \u2014C n H 2n \u2014R 2 ;\n R 2 \u2550SO 3 \u2212 , PO 4 \u2212  or COO \u2212 ; \n n=2-10; \n \n B. performing an electrodeposition process using the electrodeposit equipment with a current density of 1-80 A/dm 2  to deposit ultra-large single crystal copper grains having an average size of at least 10 \u03bcm to form a layer of copper grains on a surface of the cathode.
