    摘要: In a method for manufacturing a semiconductor device, a first conductivity type semiconductor layer and a second conductivity type semiconductor layer are sequentially grown on a growth substrate. Then, an electrode layer is formed on the second conductivity type semiconductor layer. Then, a support body is adhered to the electrode layer by providing at least one adhesive layer therebetween. Finally, at least a part of the growth substrate is removed. In this case, the adhesive layer is removable from the electrode layer.

    摘要: A nitride semiconductor light emitting device is formed by: forming a resist pattern on a first nitride semiconductor layer formed on a substrate, the resist pattern having a region whose inclination angle relative to a substrate surface changes smoothly as viewed in a cross section perpendicular to the substrate surface; etching the substrate by using the resist pattern as a mask to transfer the resist pattern to the first nitride semiconductor layer; and forming an light emitting layer on the patterned first nitride semiconductor layer. The nitride semiconductor light emitting device can emit near-white light or have a wavelength range generally equivalent to or near visible light range.

    摘要: A plurality of protrusions is formed on the C-plane substrate with a corundum structure. A base film made of a III-V compound semiconductor including Ga and N is formed on the surface of the substrate. The surface of the base film is flatter than the surface of the substrate. A light emitting structure including Ga and N is disposed on the base film. The protrusions are regularly arranged in a first direction that is tilted by less than 15 degrees with respect to the a-axis of the base film and in a second direction that is orthogonal to the first direction. Each protrusion has two first parallel sides tilted by less than 15 degrees relative to an m-axis and two second parallel sides tilted by less than 15 degrees relative to the a-axis. An interval between the two second sides is wider than an interval between the two first sides.

    摘要: There is provided a method for manufacturing a semiconductor device in which a selective growth mask for partially covering a growth substrate is formed on a growth substrate; a buffer layer that is thicker than the mask is formed on a non-mask part not covered by the mask on the growth substrate, and a predetermined facet is exposed on the surface of the buffer layer; a semiconductor film is laterally grown using the buffer layer as a starting point, and a lateral growth layer for covering the mask is formed while cavities are formed on the upper part of the mask; and a device function layer is epitaxially grown on the lateral growth layer. The cavity formation step includes a first step for growing a semiconductor film at a growth rate and a second step for growing another semiconductor film at another growth rate mutually different from the first growth rate, wherein the first and second steps are carried out a plurality of times in alternating fashion.
