Title: Metal base composite material component and manufacture thereof
Inventor: HOJO HIROSHI
IPC: H01L23/373
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To improve processing characteristics without failures such as stripping by disposing a processing member having a specific thermal expansion coefficient and hardness on a surface of a metal base composite material. SOLUTION: The metal base composite material component 1 comprises a metal base composite material 10 including dispersed particles 3 in metal matrix 2 and a processing member 5 disposed on a surface of the metal base composite material 10.

The processing member 5 has a thermal expansion coefficient of ±60% of a thermal expansion coefficient of the metal base composite material 10 while its Vickers hardness Hv is 150 or less. Thus the processing member exhibits thermal expansion characteristics approximately equivalent to those of a metal composite material including a dispersion material, thereby preventing warpage or stripping.  In addition, in figuring or drilling, it can be done within a range of thickness of the processing material without having dispersing particles of high hardness as an object for processing.

Title: Field effect transistor
Inventor: ADACHI SADAO
IPC: H01L29/205
Filed: 1985-11-12
Abstract: PURPOSE:To obtain an FET with every little leakage current by a method wherein an intermediate layer, whose composition structure is such that the composition is equal to the composition of an active layer on the side of the active layer and gradually inclined toward the side of a substrate, is provided between the active layer and the semi-insulating substrate. CONSTITUTION:A conventional step hetero junction can not block a leakage current sufficiently. When an FET whose active layer is composed of N-type channel GaAs is formed, an inclined hetero junction is employed. An AlxGa1-xAs intermediate layer 25 is provided between a GaAs active layer 24 and a semi-insulating GaAs substrate 26 and the composition ratio (x) is zero at the boundary of the layers 17 and gradually increased. The conduction band energy difference DELTAE (eV) in the intermediate layer 25 is approximately 0.8x (eV). If the thickness of the intermediate layer 25 is denoted by (d), an electric field Ebi=DELTAEc/d (v/cm) is induced in the layer. As (d) denotes the thickness of a thin film, the high voltage Ebi is induced so that electrons which flow toward the substrate and have possibility of making a leakage current are pushed back into the active layer so that the leakage current is blocked. When In1-xGaxAsyP1-y is employed, the leakage current can be also blocked effectively as described above.

IPC: H03K17/73
Filed: 1985-11-12
Abstract: PURPOSE:To obtain a gate current with a low input power and desired waveform by supplying the initial rising peak value of a gate current of a semiconductor switching element from the discharge of a capacitor charged up by a DC power supply of a high voltage and the steady-state gate current succeeding thereto from the DC power supply with a low voltage and a low internal impedance. CONSTITUTION:The 1st DC power supply 8 charges up a capacitor 4 through a resistor 6. When a signal is given from a signal generator 7 to a switching transistor (TR) 3, since the TR 3 is turned on, the charging electric charge of the capacitor 4 is given to the gate of a GTO thyristor 1 through the TR 3 and a resistor 5 to supply the rising part dIg/dt of the gate current and the initial current of the peak value Igm. Then the steady-state gate current Igo is fed from the 2nd DC power supply 9 via a diode 10, the TR 3 and the resistor 5. The 1st DC power supply 8 is used to supply the initial current only and so much power is not required. Further, the impedance between the gate and cathode of the GTO thyristor 1 is very small in general and the power is supplied from the 2nd DC power supply 9 with a low voltage.
