Abstract:
A wafer level chip scale package (WLCSP) structure and a manufacturing method are disclosed. The WLCSP structure comprises a semiconductor die and a stack. The stack comprises a protective tape and a molding compound. A portion of a first interface surface between the molding compound and the protective tape is curved. The manufacturing method comprises the steps of forming a semiconductor structure; attaching the semiconductor structure on a dummy wafer; performing a first dicing process using a first cutting tool; depositing a molding compound; removing the dummy wafer; performing a second dicing process with a second cutting tool. A first aperture of the first cutting tool is larger than a second aperture of the second cutting tool. The portion of the first interface surface being curved reduces the possibility of generation of cracks in the WLCSP structure.

Claim (Index 4):
The method for manufacturing the WLCSP structures of  claim 1 , wherein the step of forming the semiconductor structure with the plurality of semiconductor units comprises the sub-steps of:\n forming a chip array on a top surface of a substrate; and depositing a protective tape on a bottom surface of the substrate so as to form the semiconductor structure with the plurality of semiconductor units.
