Patent ID: 6919216

Claim:
A method for manufacturing a semiconductor laser apparatus, comprising the steps of: forming a first bonding layer on a semiconductor laser device having a light-emitting area which extends in a first direction perpendicular to a thickness direction thereof, in such a way that it is located on one surface portion in the thickness direction which is close to the light-emitting area of the semiconductor laser device, and that at least one part of the surface portion is exposed outside; forming a second bonding layer on a surface portion of a base onto which the semiconductor laser device is bonded, the second bonding layer having a melting point T 2 which is lower than a melting point T 1 of the first bonding layer; and heating the first and second bonding layers in a mutually pressed state at a temperature T which is lower than the melting point T 1 of the first bonding layer but higher than the melting point T 2 of the second bonding layer (T 1 >T>T 2 ) to bond the semiconductor laser device to the base.
