Patent ID: 8153507

Claim:
A method of manufacturing a high power array type semiconductor laser device, comprising: forming first and second electrodes on lower and upper surfaces of a wafer comprising a plurality of semiconductor laser arrays having a plurality of laser emission regions; forming a metal bonding layer on a surface of the second electrode of the wafer, the metal bonding layer having open regions, such that the second electrode is partially exposed, wherein the bonding layer has a plurality of separated regions, which are spaced apart from edges of an upper surface of the second electrode and are spaced apart from each other to form void regions; dicing the wafer into the semiconductor laser arrays having the metal bonding layer; after forming a metal bonding layer, having open regions, on the surface of the second electrode of the wafer, mounting each of the individually separated semiconductor laser arrays on a base with a surface of the metal bonding layer in contact with the base, wherein the metal bonding layer partially exposes the second electrode via the plurality of separated regions; and melting the metal bonding layer to fix the mounted semiconductor laser array on the base, wherein the melted metal bonding layer is pressed by the semiconductor laser array and spread in a sideward direction into the void regions, such that at least parts of the separated regions of the metal bonding layer are directly in contact with each other in the void regions.
