Title:
発光素子の製造方法
Document Type and Number:
Japanese Patent JP7182057
Kind Code:
B2
Abstract:
A method for manufacturing a light-emitting element comprises: forming a mask comprising a first film and a second film such that the mask covers a first active layer and a second nitride semiconductor layer, which comprises: forming the first film covering at least an upper surface of the second nitride semiconductor layer, and forming the second film covering the first film; while the first active layer and the second nitride semiconductor layer are covered with the mask, forming a third nitride semiconductor layer at an exposed portion of a first nitride semiconductor layer, wherein a temperature at which the third nitride semiconductor layer is formed is less than a melting point of the second film; and after the forming of the third nitride semiconductor layer, removing the mask, during which lift-off of the mask is performed by removing the first film, which also removes the second film.
