Embodiment Construction
[0029] As mentioned in the background art, the existing manufacturing methods of chromium targets have high requirements on process equipment and harsh manufacturing process conditions, resulting in high manufacturing costs and low yields of chromium targets. For this reason, the present invention provides a new method for manufacturing a chromium target. The method for manufacturing a chromium target adopts a hot pressing sintering process, and cooperates with specific temperature, pressure control and other process settings to obtain a density greater than 99.5 %, the grain size is less than 50μm, and the high-quality chromium target with uniform internal structure meets the requirements of the sputtering coating process for the chromium target. In addition, compared with the existing chromium target manufacturing process, the chromium target manufacturing method provided by the present invention requires less process equipment, and the process conditions are easy to control,...
