Abstract
The present invention provides a semiconductor device having a coating film of a predetermined thickness provided along the circumference of a semiconductor light emitting element, and provide a method for easily manufacturing the semiconductor device. A semiconductor light emitting elementthat emits blue light is mounted face down on the top face of a pedestal, and a coating filmcontaining a YAG fluorescent materialthat emits yellow light is placed so as to cover the top face and side face of the semiconductor light emitting elementand the top face of the pedestal. With the semiconductor light emitting elementand other elements placed between a first filmand a second film, the films are laminated in vacuum, thereby to fasten the coating filmonto the semiconductor light emitting element. Then the first filmand the second filmare removed, the coating filmis trimmed and the pedestalis diced, thereby to obtain the semiconductor devicehaving the coating filmof a predetermined thickness provided along the circumference of the semiconductor light emitting element
