Title: Manufacture of semiconductor device
Inventor: FUKUCHI JIYUN
IPC: H01L21/288
Filed: 1978-06-02
Abstract: PURPOSE: To enable formation of the ohmic electrode by coating the Ni film to the substrate side  of the semiconductor device of the solar battery or the like and thus burning simultaneously both  the diffusion layer side and the substrate side at a low temperature, and thus to simplify the  manufacturing process.  
     CONSTITUTION: Ni film 3 is coated to the substrate side of the semiconductor device of the solar  battery or the like comprising n-type Si substrate 1 and p + -diffusion layer 2, and then the conducting paste mainly composed of Ag and Au is printed to the diffusion layer side. Then the paste  featuring the same burning temperature as the conducting paste of the diffusion layer side, such as  the conducting paste mainly composed of Ag and featuring the burning temperatures of 550∼  650°C, is applied to film 3. And then the conducting paste for both the diffusion layer side and the  substrate side are burnt simultaneously to form electrode 4 and 5. Thus, the burning becomes  possible near 600°C which is lower than the conducting paste composed mainly of Ag, which  needs hitherto the burning temperature of more than 800°C to Si. As a result, the electrode  featuring a low-contact resistance can be obtained with no penetration to the diffusion layer.  Furthermore, the manufacturing process can be simplified since both the substrate side and the  diffusion layer side can be burnt at one time.

Abstract: PURPOSE:To prevent occurrence of crack and improve adhesiveness of an electrode, in a process of forming a bump electrode on a wiring by plating, by using a polyimide type resin film for a buffer film as an etching mask for a substrate metal. CONSTITUTION:An aluminum wiring 3 is formed on a thermal oxide film 2 provided on a substrate 1, and after piling a PSG film 4 on the wiring 3 and providing an opening, a Cr film 5 and a Cu film 6 are evaporated continuously as a plating foundation metal. And then, after a polyimide type resin film 8 is rotatingly coated and thermally hardened, the resin film 8 is etched by a resist mask whose opening is made smaller than an opening of the PSG film 4. And then, after an Au plating layer 7 is formed, a resist mask is formed in such a manner as to be extended as far as outside of the wiring 3, and by removing the resin film 8, the Cu film 6 and the Cr film 5 by etching them in turn using the resist mask as a mask, formation of a bump electrode is completed. As it is possible, by doing so, to prevent occurrence of crack on the PSG film 4 and minimize side etch of the substrate metal, it is possible to increase adhesiveness of the bump electrode and improve its reliability.

Title: Magnetic disk device
Inventor: SUZUKI MASAMI
IPC: G11B5/48
Filed: 1986-03-27
Abstract: PURPOSE:To increase storage capacity without enlarging a device by providing a magnetic head with >=two transducing parts and dividing a track on the magnetic disk by the number of the transducing parts. CONSTITUTION:Positioning is divided into two cases: one of which is that the magnetic head is positioned in a data area 10 in the inner periphery of a magnetic disk 1, as shown in figure A and B, and the other is that the magnetic head is positioned in a data area 11 on the outer periphery of said disk 1. The core slider 2 of the magnetic head is so formed that two transducing parts 8a and 8b are positioned in the inner and outer peripheries respectively. When the magnetic head is positioned in the area 10, the transducing part 8a is energized. Whereas the head is positioned in the area 11, the transducing part 8b is energized. In both cases magnetic recording information is read and written. Since the transducing parts 8a and 8b are used appropriately, an area 12 putting together the areas 10 and 11 can be used as a data area. Thus, almost an entire float insurance area 3 of the disk 1 can be used as a data area 12.

Title: Semiconductor circuit and bipolar transistor
Inventor: KONDO MASAO
IPC: H03K19/082
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce a power supply voltage, by specifying the minimum voltage between an emitter and a collector, and the maximum value if a collector current density. SOLUTION: On the basis if the dependency of the amount to positive holes stored in a found low concentration collector layer upon the collector current, the maximum value of a collector current density is set smaller than twice the collector current density wherein the cut off frequency of a bipolar transistor becomes maximum. The bipolar transistor having a low concentration collector layer or structure capable of reducing the amount of implanted positive holes is used. When the minimum value of voltage between an emitter and a collector is not more than 0.4 wherein the minimum voltage between the emitter and the collector is largely forward biased, the amount of positive holes which are injected in the low concentration layer and stored can be sufficiently reduced. Therefore, a power supply voltage can be remarkably reduced.
