Title: Manufacture of heusler alloy thin film, laminated film provided with magnetic film, magnetoresistive effect element and solid-state magnetic record element equipped with it
Inventor: SAITO YOSHIAKI
IPC: G11B5/64
Filed: 1995-03-14
Abstract: PURPOSE: To enable a Heusler alloy thin film to be effective formed even at a low temperature by a method wherein the alloy thin film is formed on a ground of metal of body-centered cubic lattice structure. CONSTITUTION: A Cr ground film 2 is formed as thick as 5nm on an MgO substrate, and a Co2 MnGe thin film 1 of thickness 5nm, a Cr film 3 of thickness 2.5nm, and a Co2 MnGe thin film 1 of thickness 5nm are successively formed thereon. Furthermore, a Cr film formed as an oxidation inhibiting non-magnetic film is formed thereon as thick as 2.5nm. The laminated film of this constitution is measured for levels of magnetoresistive effect through a four-terminal method. A resistance change rate δR/Rs (%) specified by a resistance Rs at a saturation magnetic field Hs is represented by (ΔR/Rs)max i23%, where Hs is of 130Oe. Though repetitively laminated layers on a Cr ground film are as small in number as two, the laminated film of this constitution is large in magnetoresistive effect rate under a weak magnetic field.  The laminated film is small in hysteresis and excellent in characteristics as a magnetoresistive effect element.

IPC: B05B1/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent continuous drip and to wash a tip in a short time by making the tip ultrahydrophilic. SOLUTION: A treatment liquid supplying nozzle of a substrate treating device ejects developer onto the surface of a substrate. A tip 7 in which an ejecting orifice 7b for ejecting developer is formed is made of an ultrahydrophilic material. That is to say, the outer regions and the underside of the tip 7 is made of an ultrahydrophilic layer S. Accordingly, the contact angle of these parts is almost 0 deg. and a portion D of developer adhered to the parts spreads as a thin film instead of forming spherical drops and the problem of continuous drip is prevented. Also, since the cleaning liquid is conformable to the tip 7, the adhered developer can be easily removed.

Inventor: SUGIMOTO MASAHIRO
IPC: H01L21/52
Filed: 1985-03-18
Abstract: PURPOSE:To contrive the improvement in throughput by enabling the collective formation of minute wirings. CONSTITUTION:Polyimide 12 fills up the intervals between a chip 2 and a package substrate 11 and its surface is on a level with the chip and substrate so as to make the surface flat. If a copper thin film is vapor-deposited on that, there is not possibility of disconnection due to the unevenness of height so that it is possible to spread a copper film of 1mum to a few mum followed by patterning by photo process. For the etching the copper film, ferric chloride is used. At this time, the package substrate preferably has a thermal expansion coefficient approximate to that of the chip and accordingly a substrate of silicon carbide (SiC) is suitable. In addition, as the SiC substrate also has a good heat conductivity, it is the optimum material. As the chip and the polyimide have the approximate thermal expansion coefficient with each other and also approximate to that of the package substrate, there is no possibility of disconnection of the thin film pattern 13 even if the temperature increases to the high degree during the operation and the reliability of wiring is improved.

Filed: 1985-03-19
Abstract: PURPOSE:To prevent a fault from being generated due to a surge voltage by providing a rectifying means which has been connected in series to a secondary winding in an output side of the respective transformers, a positive/negative detecting means for detecting an output voltage of the secondary winding, and a smoothing means which has been connected to an output of the positive/negative detecting means. CONSTITUTION:An induced voltage of a secondary winding by applying DC of a primary winding 113 is detected between a collector and a base of a potential detecting transistor 151, and a current of the positive direction flows to an output terminal A through a secondary winding 115 of a transformer 111, a diode 141, the collector and the emitter of the potential detecting transistor 151 from an output terminal C, for the DC applied time of the primary winding 113, namely, for the time corresponding to a positive period of a 20Hz signal. In case when a negative output use driving pulse has been outputted to a main switch transistor 122, a current of the negative direction flows to the output terminal A in the same way. The positive direction current and the negative direction current are generated alternately, therefore, a call signal output becomes AC of 20Hz. In this way, a fault by a surge voltage does not occur, and a stable operation is obtained.
