Title: Measuring method for semiconductor impurity distribution
Inventor: UENOYAMA TAKESHI
IPC: H01L21/22
Filed: 1985-10-17
Abstract: PURPOSE:To measure impurity density distribution near the surface of a bonding portion of a diode of a P-N junction or a Schottky junction by connecting a capacitor of known capacity larger than the capacity of the diode in series with the diode when an applied voltage is 0v, and measuring the voltage applied to the entirety and the impurity distribution of the bonding portion from the capacity of the entirety at that time. CONSTITUTION:A capacitor is connected in series with a P-N junction or a Schottky junction. Accordingly, even if a bias voltage is applied forward, a DC current does not flow to a circuit. Cx, C0, CT are respectively Schottky junction capacity, known capacity and the entire capacity, Vx, VT are a voltage between the Schottky junctions, and the applied voltage of the entirely. Then, there is a relationship of Cx=CTC0/(C0-CT), Vx=(1-CT/C0)V. Thus, the bias voltage VT is varied from 10V to -2V, the entire capacity VT at that time is measured, the capacity Cx and the voltage Vx are obtained to attain an impurity distribution.

Title: Piston made of tough cast iron
Inventor: FURUISHI HIROSHI
IPC: F02F3/00
Filed: 1987-09-16
Abstract: PURPOSE:To reduce casting defects due to the deflection of a core and prevent the cooling performance of a piston from being deteriorated, by forming a cooling vacant space from the inside upper part to the lower part on the inside of a piston ring groove part and forming a recessed part into a nearly U-shape along a boss from the outer peripheral surface of the piston on the boss upper side. CONSTITUTION:When a piston 11 is cast, a core for forming an inner peripheral surface 16 and a core for shaping a cooling vacant space 15 are arranged in a main mold for forming an outer shape, and the molten metal of spheroidal graphite cast iron is poured. Since, in this case, a recessed part 14 is formed in a nearly U-shaped recessed part on the outer peripheral surface of the piston 11, the need for using a core for molding the recessed part 14 is avoided. Therefore, the quantity of the core for shaping the recessed part 14 can be reduced by one, and the generation rate of the casting defect due to the deflection of the core can be reduced. Further, since the piston 11 has a sufficiently large cooling void space 15, the cooling performance of the piston 11 is not deteriorated.

Title: Manufacture of solder bump
Inventor: SATO KENJI
IPC: H01L21/60
Filed: 1990-08-31
Abstract: PURPOSE:To prevent a crack of a current metal of a part of a passivation film corresponding to a solder bump forming part by filling metal in a window of the film, and substantially flattening the part of the film corresponding to the forming part. CONSTITUTION:After the side of the electrode 2 of a semiconductor element 1 is covered with an SiO2 passivation film 3, a window is opened at the film 3, and a part corresponding to a solder bump conducting part of the electrode 2 is exposed. Then, after metal 6 such as Ni, etc., is filled in the window 3a of the film 3, a current metal 4 is uniformly formed. After a plating mask 7 is formed of the metal 4, a predetermined quantity of solder 5 is precipitated on the metal 4. Thus, since the metal 4 is scarcely cracked, a conductive malfunction is eliminated, and the bump having strong bump strength can be obtained. Accordingly, in order to mount a flip chip, the certainty of the connection is enhanced, and hence the yield of a product can be improved.

Title: Semiconductor device
Inventor: TERAGUCHI NOBUAKI
IPC: H01L31/072
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory Schottky characteristics. SOLUTION: Each layer of three-layer structure comprises a semiconductor (a collector layer 13)/a metal (a base layer 14)/the semiconductor (an emitter layer 15) is composed of a nitride. Thus, both the semiconductor layers and the metal layer are made to woke a constituent element (N) the same. Since the nitride is formed at a stoichiometric ratio of 1:1 of Nb:N in the NbN base layer 14, the formed metal nitride and nitride semiconductors display the same stoichiometric ratio. Thus, the base layer 14 and the emitter layer 15 can be formed (an interface bond of 1:1) continuously in a space, and a satisfactory Schottky junction is obtained. Accordingly, an MBT(a metal-based type transistor) having superior electrical characteristics is acquired.

Title: Oscillation circuit
Inventor: YAMADA TSUTOMU
IPC: H03B5/12
Filed: 1983-12-10
Abstract: PURPOSE:To prevent oscillations from becoming astable and incorporating a PLL pickup part in an IC by leading the 1st output from between bases of a couple of transistors (TR) constituting a differential amplifier, and obtaining the 2nd output from collectors of those TRs. CONSTITUTION:A resonance frequency component determined by a parallel resonance circuit (capacitor 15 and coil 16) as to the collector output of one TR1 in the differential TR couple is fed back positively to the base of the TR2 to perform oscillating operation. On the other hand, TRs 25 and 26 are connected to bases of the TRs 1 and 2, and collector outputs of the TRs 25 and 26 are sent to the mixer of a tuner through a buffer amplifier 28. Further, a load 31 is connected to the collector of the TR2 as a pickup output for PLL and an output is led out through a capacitor 32. In this case, the collector of the TR2 is irrelevant to the oscillating operation, so there is no evil influence exerted upon the oscillating operation even when the output is led out by connecting the load 31.

Title: Method for evaluating arrangement of parts on printed board
Inventor: SHOJI SHUICHI
IPC: H05K3/00
Filed: 1993-09-20
Abstract: PURPOSE:To reduce the time and the manhour in an evaluating method for arrangement of parts on a printed board by deciding the number of wirings that can pass among the lattice points arranged equidistantly on the board plane, dividing the number of passed wirings by the number of wirings that can pass for each lattice point to calculate the wiring capacity and outputting this capacity. CONSTITUTION:In regard to the CAD (computer aided design) of a printed board, the lattices (grids) 10 are usually arranged in a prescribed space and the pins 16 of the parts 12 and 14 are set on the intersecting points of lattices (lattice points). It is supposed under such conditions that three pieces of connected wirings pass through between two adjacent lattice points A and B based on the arrangement data and the connecting relation data. Therefore three pieces of connected wirings are decided between both points A and B. In the same way, the number of connected wirings that pass through other lattice points are decided. The number of wirings that can pass is referred to as 'wiring trace number' among those lattice points. When the number of connected wirings and the wiring trace number are decided among the lattice points, the wiring capacity is decided for each lattice point based on an equation, i.e., 'wiring capacity = (number of connected wirings)/(wiring trace number)'.
