Title: Manufacture of semiconductor device
Inventor: TAKAO SEIJI
IPC: H01L21/3205
Filed: 1987-02-24
Abstract: PURPOSE:To form an interlayer insulating film, whose flattening property is very excellent, by applying an organic film on the entire surface of the interlayer insulating film including the opening part of a provided through hole, and flattening the interlayer insulating film in two steps. CONSTITUTION:A through hole 5 is formed at first. Then, an interlayer insulating film 4 including the opening part of the through hole 5 is flattened twice. Namely, at first, a resist film or an organic resin film 6 is applied on the entire surface including the through hole 5, and flattening is performed at a depth so that the applied film 6 remains in a recess part of the interlayer insulating film and the upper edge of the opening part of the through hole 5 is exposed. At the second time, the entire surface including the exposed upper edge of the opening part of the through hole 5 is etched relatively deeply by a physical cutting means. In the second flattening step, the entire surface of the interlayer insulating film 4 which, includes of course the remaining applied film 6 on the upper surface of the film 4 and the flat part, is etched relatively deeply. Thus the very ideal flat surface is formed. The corner parts at the exposed upper edge part of the through hole 5 are removed. The device characterized by the round shape and the configuration with the excellent coverage characteristics is obtained.

Title: Method for assembling magnetic head for floppy disk
Inventor: EGAWA KAZUAKI
IPC: G11B5/265
Filed: 1985-03-04
Abstract: PURPOSE:To shorten the assembling time of a magnetic head by pressing elastically the head chip groups stacked on a groove part to weld a cover for head clamp tool and adhering the head chip groups to each other after taking out the clamp tool main body and the cover. CONSTITUTION:The both side faces C of the head chip groups are arranged evenly so as to produce no level difference, and a ceramic slider 1 of the head is pressed to adhere a gimbal adhesion face A close to a reference face D. Then head cores 2a, 2b and 3 and the rear end part of a reinfocing ceramic matter 4 are pressed independently for adhesion of each front end part to a reference face F. Thus the size (c) of the head chip group is decided by the face C, a core gap forming face B and the positioning of the face A against the face B. Then, a cover 38 for clamp tool is fixed to the clamp tool main body 32, and the head chip group is clamped to the bottom surface of a head holding groove 45 of the main body 32. The clamp tool is taken out after the external pressure of each part is released, and the head chip groups are adhered to each other. In such a way, the assembling time is shortened for a magnetic head.

Abstract: PURPOSE:To save electric power consumption and improve reliability by a method wherein a core is attracted by closing a non-contact switch when the voltage exceeds a predetermined value and afterwards a chopper circuit is activated by a timer circuit to open and close the non-contact switch interruptedly and the core is kept attracted by interrupted current. CONSTITUTION:Until the voltage of a voltage detecting circuit 11 reaches a certain value, DC current is applied to resistors 17, 18 through a diode 21 and a transistor 15 is made ON and a transistor 8 is made OFF. Therefore, no current is applied to an operation coil 1. When the voltage reaches the certain value, the current applied to the resistors 17, 18 is cut off and the transistor 15 is made OFF and the transistor 8 is made ON. Therefore, DC current is applied to the operation coil 1 and the coil 1 starts attracting the core. After some time passes, a timer circuit 12 activates a chopper circuit 13 to produce an interrupted signal. The interrupted signal is applied to the resistors 17, 18 through a diode 22 so that the transistor 15 repeats ON-state and OFF-state. Therefore, the transistor 8 also repeats ON-state and OFF-state.
