Title: Method of manufacturing copper cylinder type target for thin film coating using sputtering method through hot extrusion technique
Inventor: TEKACOONHAKI VACHAKRAN
IPC: C22F1/08
Filed: 2021-01-26
Abstract: To provide a manufacturing method for manufacturing a copper cylinder type target.SOLUTION: Manufacture of a copper cylinder type target comprises: casting a copper ingot to form a rod; and performing hot extrusion and cold drawing on the obtained copper rod without any heat treatment. For prevention against crystal grain growth of copper, it is important to control a cooling speed by immediately dipping an extruded copper target in a water bath. Preferable conditions for manufacture of copper crystal grains of 50-150 μm in grain size are that: (a) a temperature of the copper ingot before the hot extrusion is 800-900°C, and (b) a hot extrusion speed is 5-20 mm/sec. The copper ingot after the hot extrusion becomes a copper target material, which is reduced in external diameter and internal diameter through cold drawing after the extrusion, and has surface hardness less than 100 Vickers hardness. In the method, the copper cylinder type target can be manufactured which is used suitably as a copper cylinder type target for thin film coating using a sputtering technique, and an obtained thin film has high quality.SELECTED DRAWING: Figure 1
