20090160054 | NITRIDE SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - A nitride semiconductor device is provided which reduces the contact resistance at the interface between a P-type electrode and a nitride semiconductor layer. A nitride semiconductor device includes a P-type nitride semiconductor layer and a P-type electrode formed on the P-type nitride semiconductor layer. The P-type electrode is formed by successive laminations of a metal layer of a metal having a work function of 5.1 eV or more, a Pd layer of palladium, and a Ta layer of tantalum on the P-type nitride semiconductor layer. | 06-25-2009 |
20090170304 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - A method of manufacturing a semiconductor device is provided, which can reduce the contact resistance of an ohmic electrode to a p-type nitride semiconductor layer and can achieve long-term stable operation. In forming, in an electrode forming step, a p-type ohmic electrode of a metal film by successive lamination of a Pd film which is a first p-type ohmic electrode and a Ta film which is a second p-type ohmic electrode on a p-type GaN contact layer, the metal film is formed to include an oxygen atom. In the presence of an oxygen atom in the metal film, then in a heat-treatment step, the p-type ohmic electrode of the metal film is heat-treated in an atmosphere that contains no oxygen atom-containing gas. | 07-02-2009 |
