Title: Inspecting method for semiconductor device
Inventor: KONO HIROMICHI
IPC: H01L21/321
Filed: 1987-06-10
Abstract: PURPOSE:To suppress contact resistance to a semiconductor device and to accurately and easily perform an electric inspection by exposing an electrode formed by plating in a plasma containing oxygen or an ozone atmosphere to remove its surface substance. CONSTITUTION:With a photoresist film as a mask a bump 3 is plated on the plating metal 2 of a semiconductor substrate 1. Then, the film is removed and the unnecessary part of the metal 2 is removed by etching. A semiconductor device is exposed to an oxygen plasma immediately before an electric inspection to remove its surface substance. Accordingly, a contamination, readhered matter, and a modified material which affect adverse influence to its contact resistance are substantially removed. Thus, an electric measurement is thereafter conducted immediately to perform accurate measurement and inspection.

Title: Image signal switching unit
Inventor: MITOMI YUTAKA
IPC: H01H47/32
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To minimize variation of an output level caused by a change with the elapsed time of a mechanical relay by conducting at least one operation of relay switching operation corresponding to a change of switching of an image signal and relay switching operation not forming a path. SOLUTION: The switching requirement of an input image signal is received from an input selection part 8. After an outputting mechanical relay 6 is controlled in an open state, an input selecting mechanical relay 4A is controlled in an open → close → open state. Input selecting mechanical relays 4B, 4C are also controlled in an open → close → open state. The open → close →open control of a series of input selecting mechanical relays is repeatedly executed by the specified frequencies of at least one. Thereby, the relay does not keep the same state, and the variation of contact resistance caused by the generation of an oxide film for example in a contact part can be prevented. At the same time, screening is conducted, and a contact resistance variation factor such as foreign matters generated in a contact part can be removed.

Title: Radio communication equipment
Inventor: YAMADA SHINJI
IPC: H04B1/40
Filed: 1992-06-05
Abstract: PURPOSE:To attain a stable high frequency power amplifier for transmission and to reduce generation of internal spurious radiation independently on a form of a radio transmission signal by using an output of a reference oscillation unit generating a high frequency signal being a frequency reference for transmission reception for an input source and generating a negative bias voltage for high frequency power amplification. CONSTITUTION:A negative voltage generating circuit 26 is provided in the equipment. That is, even when a positive power supply voltage +Vdd is obtained from the power supply from a power supply unit 6, a negative bias voltage -VB required for a transmission final section 24 of a transmission unit 2 is obtained. Since a negative voltage generating circuit 26 inputs a reference frequency signal fc generated normally from a reference generating unit 9 as an input power supply in this case, a stable negative bias voltage is obtained independently of the form of the radio transmission signal. Moreover, since the reference frequency signal fc is used for the frequency reference for transmission reception, the possibility of spurious radiation giving adverse effect onto transmission reception is less.

Abstract: PURPOSE:To prevent a central processing unit CPU from losing control information by providing an input/output controller and a system controller with means which transfer control information held in the storage means of the input/output controller to the system controller before initialization of the input/output controller. CONSTITUTION:When receive an initializing command from a CPU 2, an input/ output controller (IOC) 5 transmits a transfer request for the purpose of requesting transfer of control information to a system controller (SCU) 3 and receives the response from the SCU 3 to transfer control information stored in the storage means in the IOC 5 to the SCU 3 and initializes the IOC 5 itself after completion of transfer of control information. The SCU 3 transmits the response, which indicates that the SCU 3 cannot receive information, to the IOC and receives control information transferred from the IOC to store this information in a secondary storage device 4 connected to the SCU 3. Thus, the storage means in the input/output controller is prevented from being initialized by the initializing command, and the CPU is prevented from losing control information which indicates the cause of trouble.
