Abstract:
1. A method of manufacturing a semiconductor light emitting element comprising following steps of: (a) forming a multilayered nitride semiconductor layer on a first surface of a first wafer which is configured transmit a first light, (b) bonding a second wafer on the multilayered nitride semiconductor layer, said step of bonding a second wafer being performed after said step of forming a multilayered nitride semiconductor layer, (c) forming a groove having a depth extends from the second surface of said first wafer to at least said multilayered nitride semiconductor layer, (d) applying the first light to the third surface of the multilayered nitride semiconductor layer through the first wafer so as to dissolve a nitride semiconductor located in said third surface of said multilayered nitride semiconductor layer, (e) separating said first wafer from said first nitride semiconductor layer; and (f) cutting said first nitride semiconductor layer, said second nitride semiconductor layer, and said second wafer along said groove so as to be divided into a plurality of semiconductor light emitting element,
