Abstract
PURPOSE:To inhibit the damage to a crystal to the minimum and to contrive the improvement of a yield by a method wherein jigs are each provided with a step part for avoiding the contact of each laser end surface with a plane supporting stand. CONSTITUTION:When a protective film is formed on upper edge faces 1a of semiconductor lasers of 300X110mum or thereabouts, the barlike lasers 1 of a length of 15mum or thereabouts are each placed on the step parts of barlike L-shaped jigs 5, which are each 15mm or thereabouts in length and are each provided with a step part, facing upward the laser upper edge face 1a and facing downward laser lower edge face 1b, the lasers 1 and the jigs 5 are alternately superposed a plurality of pieces, both ends are pinched in between jigs 3 for fixing by the jigs 3 and the jigs 5 are fixed on a plane supporting stand 4. According to such a way, the lasers do not come into contact with the stand 4 because there exists an interval between the stand 4 and each laser lower edge face 1b. In this state, the protective film is formed on the semiconductor laser upper edge faces 1a by sputtering and so on. Then, the lower edge faces 1b are arranged facing upward and a protective film is formed on the laser edge faces 1b as well in the same way as the above.
