发明名称 Light emitting diode device and method for producing same
摘要 A light emitting diode device comprises an n type silicon carbide substrate having first and second major surfaces opposite to each other at least inclined at a predetermined angle not less than 3 DEG from a {0001} plane, an n type silicon carbide layer grown on the first major surface, a p type silicon carbide layer grown on the n type silicon carbide layer, a p type ohmic electrode formed on a partial area of the p type silicon carbide layer, and an n type ohmic electrode formed on a partial area of the second major surface. The diode element has a substantially trapezoidal form in a cross section orthogonal to the first major surface. The diode element has the side of the p type silicon carbide layer broader than the side of the second major surface and is supported at the side of the type silicon carbide layer fixed to a supporting stem.
