Title: Attaching method for metallic electrode to semiconductor
Inventor: WADA YOSHIKI
IPC: H01L29/872
Filed: 1982-10-16
Abstract: PURPOSE:To form a Ta electrode only by a body-centered cubic crystal, and to obstruct the undesired intrusion of the wiring metal of an upper layer by etching GaAs in vacuum and instantaneously depositing Ta. CONSTITUTION:GaAs is placed on a water-cooled holder in a treating chamber, the inside of the chamber is evacuated, the chamber is filled with Ar gas up to 60m Torr, a Ta source is etched through sputtering treatment using high frequency first and purified, and the inside of the chamber is evacuated up to high vacuum. The holder is cooled by water, Ar gas is discharged up to 30m Torr and high frequency is applied, GaAs is purified through reverse sputtering treatment, and the inside of the chamber is evacuated up to high vacuum again. Ar gas is kept at 30m Torr, GaAs is biassed to a negative value, Ta is high- frequency sputtering treated, and the metallic electrode in Ta is formed. Ta obtained at that time substantially has the crystalline structure of body-centered cubic structure, the wiring metal formed on Ta cannot intrude to GaAs even at a high temperature, and the characteristics of GaAs do not change.

Patent JP-H0628053-A (JP)
Title: Electronic apparatus having stand-by mode
Inventor: SHIBATA YASUHIDE
IPC: G06F1/04
Filed: 1992-07-09
Abstract: PURPOSE:To considerably suppress power consumption to a low level at the time of a standby mode by switching clocks to be used for an operation mode and the stand-by mode. CONSTITUTION:In the stand-by mode, a VA power supply is disconnected and only VL power is supplied from a power supply control part 7. During the period, the operation of a clock generator 1 and an MPU 5 receiving VA power supply is stopped. Operation required in the stand-by mode is only refreshment operation to a DRAM 6. Since highly accurate timing is not required for the refreshment operation, the accuracy of a VCO oscillator 2 is sufficient for clocks and a clock selecting circuit 3 selects CLKVCO and outputs the selected CLKVCO to a memory controller 4. The controller 4 drives a timer and executes refreshment operation, so that power consumption in the stand-by mode can be suppressed to a low level.

IPC: F16L47/02
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To control fusion by detecting fusion failure of an electric fusion coupler due to existence of moisture on a connecting part. SOLUTION: A microphone 20 collects sound generated at the time of fusion in the neighbourhood of an EF coupler 11. A filter 23 passes a frequency band where moisture evaporating sound can exist out of the sound collected by the microphone 20 to an evaporating sound detection part 24.
