摘要： A semiconductor light emitting device having multi-layer structure of group-3 nitride-based semiconductors is disclosed. The light emitting device has lower density of threading dislocation extending from a boundary of a crystal substrate through the multi-layer structure, thereby obtaining good luminescence characteristics. The nitride semiconductor light emitting device has the multi-layer structure. The multi-layer structure comprises a first crystal layer containing substantially pyramidal crystal grains, each of grains has a crystal face non-parallel to a surface of the substrate, and the pyramidal crystal grains are distributed at random like islands. The structure further comprises a second crystal layer formed on the first crystal layer with a compound having a different lattice constant from that of the first crystal layer. The second crystal layer smoothes a surface of the first crystal layer parallel to the surface of the substrate.

摘要： A group III nitride semiconductor device is disclosed which has a reduced number of threading dislocations adversely affecting characteristics of the group III nitride semiconductor device. A method for manufacturing the group III nitride semiconductor device controls pit formation in a GaN layer formed on a sapphire substrate. First, a low temperature buffer layer is formed on a sapphire substrate by MOCVD. An undoped GaN layer having a predetermined thickness is then grown on the low temperature buffer layer. Next, a GaN layer containing magnesium as a dopant is formed on the layer at a lower pressure than that of depositing the GaN layer, which results in filling pits generated on the GaN layer to flatten the surface of another GaN layer.

摘要： In a semiconductor light-emitting device having a multilayered structure which consists essentially of layers of Group III nitride semiconductors (AlxGa1−x) 1−yInyN (0≦x≦1, 0≦y≦1) which are different from each other in chemical composition ratio, generation of cracks at an interface propagating from an interface between adjacent layers is prevented. Two adjacent layers within the multilayered structure, which include a lower layer having a lattice constant larger than a lattice constant of an upper layer of the two adjacent layers, have a portion close to the interface of the two adjacent layers doped such that an element different from the Group III nitride semiconductors is added in a higher concentration, i.e. in a higher distribution density than in other portions thereof.

摘要： A double-sided coated substrate transport device (1) is described. A die head for front face coating (3) and a die head for back face coating (4) coat a coating liquid onto a substrate 1. A drying oven (5) dries the coating liquid applied to the substrate (1), to form coating films on the front and back faces of the substrate (1). A first and second rotating body unit (20A, 20B) are respectively furnished independently at widthwise edge sections of the substrate (1). Each of the first and second rotating body units has a free roller (21) and a drive roller (22) constituting a pair of rotating bodies, and a rotating body swivel section (23). The free roller (21) and the drive roller (22) grip the widthwise edge sections of the substrate (1) from the front and back sides. The rotating body swivel section (23) allows the orientation of the free roller (21) and the drive roller (22), respectively, to be modified separately for the first rotating body unit (20A) and the second rotating body unit (20B), so that the rotation axis of the free roller (21) and the drive roller (22) is inclined towards the downstream side in the substrate transport direction as seen from the outside in the substrate widthwise direction, with respect to a line perpendicular to the substrate transport direction.
