Title: Leadframe for semiconductor device
Inventor: CHINDA SATOSHI
IPC: C25D7/00
Filed: 1991-02-05
Abstract: PURPOSE:To provide a leadframe, for use in a semiconductor, coated with a nickel plating, which possesses a superior solderability without a flux. CONSTITUTION:A leadframe, for use in a semiconductor device, is composed of a substrate, which is made up of copper, a copper alloy or an iron alloy, coated with a nickel-cobalt alloy plating. The substrate thus plated is further coated with a nickel-iron-phosphorus alloy plating, which is composed of, in percent by weight, 1-10 iron, 2-10 phosphorus, and the balance nickel. Since an oxide layer, produced by the nickel-cobalt alloy plating, is not as hard as that produced by a pure nickel plating, the nickel-cobalt alloy plating is improved in solderability. However, the nickel-cobalt alloy plating tends to be impaired in colorfastness when used solely, and suffers the progressive growth of an oxide layer, thereby being deteriorated in solderability. To prevent this, the surface of the nickel-cobalt alloy plating is further coated with a thin film of the amorphous nickel-iron-phosphorus alloy plating which is superior in anticorrosion and not liable to the growth of the oxide film.

Abstract: PROBLEM TO BE SOLVED: To maintain a cell data length at a fixed value and to reduce the capacity of a buffer memory by continuing to successively overwrite data that exceeds a fixed number in the leading address of the next cell when long cell data is transferred.

Filed: 1979-03-24
Abstract: PURPOSE: To exercise easily temperature control over a load by adjusting a switch temperature resistance so that a Triac will be truned ON when the temperature of a heat-sensitive thyristor is low and turned OFF when high.  
     CONSTITUTION: In a temperature control circuit which makes a temperature adjustment of a load by having control over both-way three-terminal thyristor Triac 9 to turn ON at a fixed temperature and below and OFF at the temperature or above, Triac 9 turns ON, when the temperature of heat-sensitive thyristor 8 is low and a break-over voltage is less than the Zener voltage of Zener diode 6, to supply power to load 2.

In this case, the control temperature is set by switch temperature adjusting resistance 7 between the cathode and gate of thyristor 8, so that the temperature control over load 2 can easily be exercised.

Title: System and method for etching conductive thin film
Inventor: NAKAGAWA SATOSHI
IPC: H05H1/46
Filed: 1992-02-24
Abstract: PURPOSE:To control the etching shape of the title system by changing the self bias of the device. CONSTITUTION:An etching gas is introduced into an etching chamber 1 through a gas introducing port 11 and the gas is discharged through an exhaust port 12 so as to maintain the chamber 1 at a desired pressure. When high-frequency power is impressed upon a high-frequency impression electrode 3 from a high-frequency power source 5, plasma is generated between the electrode 3 and chamber 1. A substrate 2 to be etched is placed on the electrode 3 and etched by reactive ions. At the time of etching the substrate 2, a self bias is applied across the substrate 2 and the potential of the substrate 2 becomes negative. Because of the negative potential, ions having positive charges are accelerated and directional etching is performed. The self bias can be changed by, for example, further impressing a DC potential impressed upon a platinum contact 7 from a DC power source 9 through a contact connecting line 8 upon a conductive thin film 15 on the surface of the substrate 2.

Title: Logical block for digital integrated circuit
Inventor: YOSHIDA MASAAKI
IPC: G01R31/28
Filed: 1982-03-08
Abstract: PURPOSE:To obtain a logical block which is incorporated into an integrated circuit itself so as to attain a logical function test even with a complicated circuit, by adding a signal line detouring a flip-flop. CONSTITUTION:When control signals are set as C1=0 and C2=1, a data Q is delivered via a flip-flop 31. That is, on a logical block, a multiplexer 42 is made conductive to an SIN by the control signal C1. As a result, a logical block functions as a linear shift register that uses the SIN and SOUT as an input and an output respectively and therefore attains the function as a shift register of a scan path. At the same time, the output of an exclusive OR gate 43 of a feedback loop is connected directly in the above-mentioned mode so as to be used to the data Q of a basic unit. Thus the logical block functions as a linear feedback shift register to perform the function of a test pattern generator.
