Patent ID: 8265436

Claim:
A bonding system for alignment, comprising: an optical semiconductor, comprising: a light source; and a plurality of protruded elements extending above a surface of the optical semiconductor; a first metallized layer disposed on a surface of each protruded element of the plurality of protruded elements; and a semiconductor bench, comprising: a light receiving element, serving as an input terminal of the light source, wherein the light receiving element is aligned to the light source in a pressure applying direction; a plurality of recess elements extending downward from a surface of the semiconductor bench, wherein at least a sidewall of each protruded element of the plurality of protruded elements or a sidewall of each recess element of the plurality of recess elements is slanted; a second metallized layer disposed at a bottom surface of each recess element of the plurality of recess elements, wherein the optical semiconductor is integrated with the semiconductor bench by sliding the plurality of protruded elements correspondingly into the plurality of recess elements and by fusing the first metallized layer with the second metallized layer.
