Abstract
A method for forming a chip package structure is provided. The method includes forming a first conductive bump and a first ring-like structure over a chip. The first ring-like structure surrounds the first conductive bump, the first ring-like structure and the first conductive bump are made of a same first material, the chip includes an interconnect structure, and the first ring-like structure is electrically insulated from the interconnect structure and the first conductive bump. The method includes bonding the chip to a substrate through the first conductive bump.
