Abstract
PURPOSE:To accurately arrange a resonator length and to obtain a good cleavage plane by a method wherein a broken line type etching groove is formed in crossing a band like operational area and in avoiding a part of this band like area, and a crystal is cleaved along this groove. CONSTITUTION:A V groove 10 is formed on a main plane wherein a stripe electrode of a wafer 1 is formed. At this time, this groove 10 is formed in a broken line type crossing the electrode 2 positioned at the upper part of a band like operational area 4 and avoiding the peripheral area of the electrode 2. When a cleavage is performed along the groove 10 of the wafer 1 like this, even if the direction of the groove 10 is slightly out of a crystal azimuth, a step difference occurs only a lower part of the groove 10 and does not occur in an area 4 contributing to a laser oscillation. And since the width of a stripe is ordinarily 20mum or less, if the groove 10 is separated with a spacing of approximately 50mum, the influence of a step difference does not appear in the operational area. Whereas, the width of an ordinary element is approximately 300mum, as a result, even if there is no groove 10 of approximately 50mum, there occurs no fault for cleavage.
