IPC: H01L21/8238
Filed: 1984-04-19
Abstract: PURPOSE:To enable to set different bias potential independently and simultaneously on the semiconductor device whereon an MOS transistor having complementary characteristics is formed. CONSTITUTION:The first conductive type diffusion regions (p-wells) 5A-5D are formed on a plurality of selected places on an epitaxial layer 2. At that time, said diffusion regions 5A-5D are formed by diffusion in such a manner that they reach the substrate region 1 located on the lower side of them. Accordingly, the regions (n-wells) 4A and 4B consisting of a part of an epitaxial layer 2 are completely separated by the diffusion regions (p-wells) 5A, 5B, 5C and 5D and the first conductive type substrate region 1. Also, the first conductive type diffusion region (p-well) 6 is formed on the epitaxial layer of a buried diffusion layer 3, and as a result, said diffusion region 6 is completely isolated by the regions (n-wells) 4C and 4D consisting of a part of the second conductive type epitaxial layer 2 and the second conductive type buried layer 3, thereby enabling to set the bias potential independently.

Title: Composite type thin-film magnetic head and production thereof
Inventor: KANEKO HIDEKI
IPC: G11B5/60
Filed: 1989-03-29
Abstract: PURPOSE:To obtain stable floating characteristics and good magnetic characteristics by adopting an integral structure which inserts a protective film incorporating a record ing and reproducing element formed on the side face of a 1st slider to a 2nd slider. CONSTITUTION:A substrate for forming the recording and reproducing element is produced by successively forming the films of Al2O3 as an insulating layer, a 'SENDUST(R)' alloy, etc., as an MR element and inductive element, and Al2O3 as the protective film 28 on an Al2O3TiC substrate. This substrate is cut to an array shape in the thickness direction of the slider and the cut face is previously polished to produce the 1st slider substrate 1. The 2nd slider substrate (Al2O3TiC) 2 having the same size as the size of the substrate 1 is then adhered by an adhesive agent 3 so as to insert the protective film 28 and the floating surface side is polished to a specular surface until the recording element is exposed. Central grooves 24', 24'' are ground to form 1st to 3rd floating surfaces 4 to 6; thereafter, the substrate is cut to the individual sliders. Since the steps of the protective film 28 and the floating surfaces 4 to 6 are decreased, the recording and reproducing characteristics are im proved and since the right and left floating surfaces 4, 6 are formed of the same material, the excellent wear resistance and the stable floating characteristics are obtd.
