Publication number: 20240102194Abstract: A plating system and a method thereof are disclosed. The plating system performs a N-stage plating drilling filling process in which a M-th stage plating drilling filling process with a M-th current density is performed on a hole of a substrate for a M-th plating time to form a M-th plating layer on the to-be-plated layer, wherein N is a positive integer equal to or greater than 3, and M is a positive integer positive integer in a range of 1 to N. Therefore, the technical effect of providing a higher drilling filling rate than conventional plating filling technology under a condition that a total thickness of plating layers is fixed can be achieved.Type: ApplicationFiled: August 7, 2023Publication date: March 28, 2024Inventors: Cheng-EN HO, Yu-Lian CHEN, Cheng-Chi WANG, Yu-Jen CHANG, Yung-Sheng LU, Cheng-Yu LEE, Yu-Ming LIN
