Patent ID: 7709282

Claim:
A production method for producing a light-emitting device in which a light-emitting layer at least including an n-type semiconductor layer and a p-type semiconductor layer is layered on a transparent crystal substrate, comprising: applying a silicon organic solution to at least a part of the transparent crystal substrate or the light-emitting layer to form a transfer layer on at least a part of the transparent crystal substrate or the light-emitting layer wherein said transfer layer is 1 to 2 μm; softening or setting said transfer layer upon supplying an energy thereto; pressing a mold formed with a minute unevenness structure against the transfer layer to transfer the minute unevenness structure to an outer surface of the transfer layer under a pressure of 5 MPa or higher and 150 MPa or lower wherein a pitch is 1 to 3 μm, wherein the mold has an upper flat portion located near a bottom of the minute unevenness structure to be transferred and a lower flat portion located at a position about a thickness of an upper semiconductor layer of the light-emitting layer, the upper flat portion and the lower flat portion are transferred together with the minute unevenness structure to the transfer layer; and forming electrode-forming portions by etching the upper and lower semiconductor layers of the light-emitting layer when dry etching is carried out using the transfer layer as a resist mask; and dry etching the transfer layer with a chlorine gas using the transfer layer as a resist mask to form a minute unevenness structure for preventing multiple reflection in the transparent crystal substrate or the light-emitting layer.
