IPC: G11B5/127
Filed: 1990-02-01
Abstract: PURPOSE:To shorten the process for production by making common use of a plating underlying film provided to form a main magnetic pole connecting layer on a 3rd interlayer insulating layer as a mask for plasma etching. CONSTITUTION:After the main magnetic pole connecting layer 22 is formed by a mask plating method via the plating underlying film 21 in the central part of a coil, the plating underlying film 21 is patterned to prescribed patterns and the parts facing a recording medium of the interlayer insulating layers 2 to 4 are selectively removed with the plating underlying film pattern 23 as a mask. An inorg. insulating layer 24 is formed on the interlayer insulating layer 4 including the substrate surface in these removed parts and the main magnetic pole connecting layer 22 and the main magnetic pole connecting layer 22 is polished and flattened together with the inorg. insulating layer 24 in such a manner that the connecting layer remains by as much as the prescribed thickness. A main magnetic pole 26 is so formed on the flattened main magnetic pole connecting layer 22 and inorg. insulating layer 24 that the front end part thereof is exposed on a medium-facing surface 28. The process for production is shortened in this way.

Title: Manufacture of semiconductor device
Inventor: ITO KATSU
IPC: H01L29/78
Filed: 1986-02-07
Abstract: PURPOSE:To improve the mechanical and electrical properties of SOS structured semiconductor device by a method wherein, after filling the space between active elements with polycrystalline silicon, polycrystalline silicon region is oxidized in a short time reaching a sapphire substrare to be a dielectric isolation region between active regions. CONSTITUTION:Various properties of transistor to be formed on the upper part of a single crystal can be prevented from deteriorating because the impurity such as aluminium from sapphire substrate 10 is thermal-diffused on an insular single crystal silicon layer 12 since, in case of forming a silicon dioxide film 25 (15), the oxidizing speed of polycrystalline silicon film 29 is faster than that of the single crystal silicon layer 12. Besides, the oxidizing speed can be further accelerated by containing high concentration N-type or P-type impurity in the polycrystallin silicon layer 29. Furthermore, metallic interconnections 17, 18 need not pass through any notable step difference since there is almost no step difference between the surface of silicon dioxide film 25 and that of single crystal silicon layer 12. Through these procedures, it is possible to avoid a trouble such as disconnection of metallic interconnections.

Title: Grounding circuit for high-frequency active element
Inventor: ICHIKAWA YUICHI
IPC: H05K1/18
Filed: 1994-02-23
Abstract: PURPOSE:To provide a circuit for grounding high-frequency active elements perfectly. CONSTITUTION:The emitter E of a transistor 11 mounted on an electronic circuit board and operated by a high-frequency signal is grounded by connecting it through a through hole to a shield conductor formed on the rear of the board, and is also connected to one end of an open stub 15 of a length of 1/4lambda with respect to the operating frequency of the transistor 11. By doing this way, the voltage amplitude of the open stub 15 of a length 1/4lambda becomes maximum at its open end, and zero at the other end, so the emitter E terminal of the transistor 11 is grounded in terms of high frequency. Consequently, the high-frequency grounding of the transistor 11 becomes perfect, and it becomes possible for the transistor 11 to exhibit its performance fully without causing oscillation, etc.
