Patent number: 10743411Abstract: A ceramic substrate component suitable for high-power chips includes a ceramic substrate body and at least one raised metal pad. The ceramic substrate body has an upper surface and a lower surface opposite to the upper surface. The raised metal pad includes a base portion and a top layer. The base portion, which is attached to the upper surface of the ceramic substrate body, has a thickness between 10 and 300 micrometers, and a thermal expansion coefficient greater than the ceramic substrate body. The top layer is formed on the base portion and adapted to install a high-power chip thereon. The top layer extends an area less than the base portion but greater than the high-power chip, and has a thermal expansion coefficient greater than the ceramic substrate body. As such, damages due to thermal stress occurring between the base portion and the ceramic substrate body can be mitigated.Type: GrantFiled: January 8, 2020Date of Patent: August 11, 2020Assignees: ICP Technology Co., Ltd., Industrial Technology Research InstituteInventors: Ho-Chieh Yu, Chen-Cheng-Lung Liao, Chun-Yu Lin, Hsiao-Ming Chang, Jing-Yao Chang, Tao-Chih Chang
