Patent number: 11694950Abstract: A semiconductor package has a substrate, a chip and an encapsulation. The substrate has a dielectric layer, a copper wiring layer and a solder resist layer formed thereon. The copper wiring layer is formed on the dielectric layer and is covered by the solder resist layer. The solder resist layer has a chip area defined thereon and an annular opening formed thereon. The annular opening surrounds the chip area and exposes part of the copper wiring layer. The chip is mounted on the chip area and is encapsulated by the encapsulation. Therefore, the semiconductor package with the annular opening makes the solder resist layer discontinuous, and the concentration stress is decreased to avoid a crack formed on the solder resist layer or the copper wiring layer when doing thermal-cycle test.Type: GrantFiled: March 11, 2021Date of Patent: July 4, 2023Assignee: Powertech Technology Inc.Inventors: Chih-Yen Su, Chun-Te Lin
