Abstract: An object of the present invention is to reduce the resistance of an electrode of a Group III nitride semiconductor. A thin Si film and a thin Ti film are formed selectively in a contact formation region on a surface of an AlGaN layer as a Group III nitride semiconductor layer formed on a substrate, and the resulting substrate is heat-treated at a high temperature. By the heat treatment, Si is diffused into the AlGaN layer in the ohmic contact formation region at a concentration of about 1020 cm3. Further, an electron density sufficiently high to provide an ohmic characteristic through a reaction between Si and Ti is provided. Thus, a low resistance TiSi2 portion resulting from the reaction between Si and Ti, a TiN portion resulting from a reaction between Ti and AlGaN and a Group III metal portion of Ga and Al devoid of nitrogen are formed in the contact formation region thereby to provide a low resistance electrode film mainly comprising TiSi2.

Abstract: A magnetic head includes a first magnetic core half having a coil winding groove coupled to a second magnetic core half having an auxiliary core element accommodated in the coil winding groove, such that a magnetic gap is defined between joining faces of the first and second core halves. Alternatively, a composite magnetic head includes a pair of magnetic heads that have magnetic gaps with different azimuth angles from each other and disposed closely in an opposing relationship to each other in a head feeding direction so as to define respective track widths and a track pitch. A thin conductor film is formed on at least one of a pair of opposing faces of the magnetic heads for intercepting leakage fluxes from the magnetic gap of the other magnetic head. The thin conductor film has a thickness and is located such that the track pitch formed by the magnetic heads is substantially independent of the thickness of the thin conductor film. A method of producing a magnetic head includes forming a track width restricting groove on each of a pair of head core blocks. The blocks are fused together with glass when aligned with the restricting groove. An additional groove is formed at an angle substantially equal to the azimuth angle of the magnetic gap on at least one of the pairs of faces on the blocks and the blocks are cut in a direction substantially perpendicular to the bottom face of the additional groove.
