Abstract
A method for fabricating a group-III nitride semiconductor laser device stably supplies laser cavity mirrors having a low lasing threshold current through the use of a semi-polar plane. A bladeis forced down through a first region ERto keep the first region ERsqueezed between a support member Hand a movable member Htogether with a part of a protective sheet TF in contact with the first region ERwhile the tension generated in the area of the protective sheet TF in contact with the first region ERwith the movable member Hincreases until the semi-polar principal surface SF at an end face EGof the first region ERtilts by a deflection angle THETA from the semi-polar principal surface SF of a second region ER, and a force is thereby generated in the first region ERin a direction opposite to the direction of travel of the bladetoward the first region ER. For example, an angle ALPHA is within the range of 71 degrees to 79 degrees, and the deflection angle THETA is within the range of 11 to 19.
