Patent ID: 8168459

Claim:
A method for manufacturing a semiconductor light-emitting device comprising: a step for forming a semiconductor film on top of a growth substrate; a step for etching said semiconductor film along element dividing lines to form dividing grooves in said semiconductor film reaching the growth substrate and dividing said semiconductor film; a step for filling said dividing grooves with a resin having laser absorbing properties; a step for forming on top of said semiconductor film a support member for supporting said semiconductor film; and a step for directing a laser at said growth substrate from a rear surface, breaking down said semiconductor film and said resin near an interface with said growth substrate, and delaminating said growth substrate from said semiconductor film, wherein said laser directing step further comprises a first laser exposure step for performing laser exposure at an energy density at which the resin is broken down but said semiconductor film is not broken down, in a range including a portion adjacent to at least one section of said semiconductor film divided by said dividing grooves and said at least one section of said resin, and a second exposure step for performing laser exposure at an energy density at which said semiconductor film can be broken down in a range including said at least one section.
