IPC: H01L33/16
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable nitride semiconductor element arranged to have a high degree of freedom in the design and fabrication of the element. SOLUTION: Essential part of the nitride semiconductor element is formed on a sapphire substrate 10 and comprises a protrusion-like nuclide crystal layer 11 having an insulation layer 12 on one side face, and a GaN layer 15 grown on the substrate and the nuclide crystal layer by lateral growth method. Since the GaN layer is grown by lateral growth method only from the exposed side face not covered with the insulation layer of the nuclide crystal layer, the GaN layer is grown asymmetrically in the lateral direction, and an association part 32 is formed in the thickness direction of the GaN layer from the vicinity of boundary of the nuclide crystal layer and the insulation layer.  Although the association part exists in the center of the nuclide crystal layers in the conventional structure, it exists in the vicinity of boundary between the nuclide crystal layer and the insulation layer in this example. Since the WL of low defect density region is represented by a relation WP≈WO+WL, and WL>WO assuming the pitch of the nuclide crystal layer is WP and the width thereof is WO, and thereby it is represented by a relation WL>0.5×WP; a significantly larger value of WL can be obtained as compared with a conventional structure.
