Patent ID: 7011982

Claim:
A method for manufacturing a nitride semiconductor laser device comprising a multi-layer body which is a plurality of sequentially stacked crystal layers made of a group-III nitride semiconductor (Al x Ga 1-x ) 1-y In y N (0≦x≦1, 0≦y≦1), the method comprising: a wafer forming step for forming a laser wafer by stacking said multi-layer body on a first substrate; a cut-out portion forming step for forming a cut-out portion on a second substrate; a gluing step for aligning and gluing a surface of said second substrate in which said cut-out portion has been formed onto said multi-layer body; a step for removing said first substrate from said laser wafer; and a cleaving step for forming a cavity mirror by cleaving a glued body comprising said second substrate and said multi-layer body.
