Abstract:
A method for producing a semiconductor element comprising the steps of:forming a plurality of grooves on a first surface of a semiconductor multi-layer structure along a first direction and having a depth of about 0.5 &mgr;m or more and about 5 &mgr;m or less from the first surface; forming a plurality of multi-element bars by cleaving the semiconductor multi-layer structure along a second direction; placing at least one of the plurality of multi-element bars on a support stage; and cleaving the at least one of the plurality of multi-element bars along the plurality of grooves by moving a pressure member in a longitudinal direction of the at least one of the plurality of multi-element bars while a constant load is applied by the pressure member to a second surface of the at least one of the plurality of multi-element bars, the second surface being opposite a third surface corresponding to the first surface of the at least one of the plurality of multi-element bars.
