Abstract:
A solder pad, a semiconductor chip including the solder pad, and a forming method therefor are provided. A solder pad includes at least two metal layers and a dielectric layer located between adjacent metal layers. The solder pad includes a laser drilling region; the dielectric layer is provided with an opening corresponding to the laser drilling region; a metal plug is provided in the opening, both ends of the metal plug being respectively in contact with the adjacent metal layers. A method for forming a solder pad improves the quality of laser drilling performed on a solder pad and reduces the difficulty of the laser drilling; laser acts on a metal substance without being in contact with a dielectric layer, so as to effectively prevent a dielectric layer from heat distortion.

Claim (Index 6):
The contact pad according to  claim 1 , wherein the metal layer comprises a barrier layer tightly integrated with a protection layer or the dielectric layer of the contact pad, an intermediate metal layer bonded with the barrier layer, and an anti-reflection layer deposited on the intermediate metal layer.
