Title: Growth method for compound semiconductor
Inventor: ONOZAWA SACHIKO
IPC: H01L21/205
Filed: 1987-12-19
Abstract: PURPOSE:To deposit a semi-insulating compound semiconductor containing arsenic on an underneath layer coated with germanium layer by a method wherein a reactive gas used for crystal deposition is fed only when the crystal deposition requirements fit for the deposition of compound semiconductor are satisfactorily met. CONSTITUTION:An underneath layer is mounted in the deposition chamber of a crystal depositing device while hydrogen gas is fed to the chamber cut off from the air for specified time. Simultaneously, an underneath layer is heated up to the temperature fit for cleaning process. Next, the heating process is stopped and when the underneath layer is cooled down to the temperature for depositing a GaAs buffer layer, AsH3 and TMG are simultaneously fed to the chamber to form a non-doped GaAs layer on the underneath layer. After finishing the deposition, TEV is led into the deposition chamber to deposit the GaAs layer doped with vanadium. After the feeding of TEV is stopped, the non-doped GaAs layer as an active layer is deposited. Finally, when the underneath layer is cooled down to the room temperature, the feeding of hydrogen gas is stopped to form the underneath layer for mounting the specified compound semiconductor thereon.

Title: Switched capacitor circuit
Inventor: TAKAHASHI MITSURU
IPC: H03F3/70
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a switched capacitor circuit which prevents a leak current increase and performs high accuracy operation with a low power supply voltage to attain low power consumption. SOLUTION: In an NMOS transistor that constitutes each switch 5 to 8, when a control voltage of each substrate voltage control terminal 52, 62, 72 and 82 is increased, a threshold voltage decreases. In a PMOS transistor, when a control voltage that is applied to each substrate voltage control terminal 53, 63, 73 and 83 is decreased, the threshold voltage increases. In an integrator 11, if a substrate voltage is controlled to increase an absolute value of the threshold value when each switch 5 to 8 is off, a leak current reduces and integration precision is improved. If the substrate voltage is controlled to reduce the absolute value of the threshold value when each switch 5 to 8 is on, it is possible to reduce a power supply voltage and to attain low power consumption, as it is possible to surely turn on the transistors with the low power supply voltage.
