Title: Semiconductor device and testing method therefor
Inventor: MATSUZAWA MASAO
IPC: H01L27/04
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a test circuit capable of preventing a defective semiconductor device from being determined as a nondefective one in a test, and capable of detecting surely the defective devices. SOLUTION: An input buffer circuit 41 has an output buffer 44 and switches 42, 43 for a test. The both switches 42, 43 are connected usually to the first contact (an upper side contact). The both switches 42, 43 are connected to the second contact at the time of the test. A condition (amplifying operation/high impedance) of the buffer 44 is thereby controlled by a signal impressed to a terminal Ta, and a signal of a terminal Tb is output to a pad SPAD via the buffer 44. Therefore, the quality of the buffer 44 is determined by changing the signals of the terminals Ta, Tb to check the pad SPAD. An output enable singal SENO is also checked via a monitor terminal MON.

Title: Magnetic field measuring instrument
Inventor: YOSHIDA AKIRA
IPC: H01L39/22
Filed: 1990-06-08
Abstract: PURPOSE:To measure a magnetic field with high sensitivity and high resolution by measuring a magnetic field produced by an object of measurement by putting one end part of a high-magnetic-permeability member closely to or in contact with the object of measurement. CONSTITUTION:The magnetic field produced by the object 11 of measurement is measured through the high-magnetic-permeability member 7, a 1st coil 8, a 2nd coil 9, and a SQUID 10. The high-magnetic-permeability member 7 is only arranged so that the part which crosses the 1st coil 8 is inside a dewer 12, and at least one end part 7A can be arranged outside the dewer 12. Consequently, the one end part 7A of the high-magnetic-permeability 7 can be put closely to or in contact with the object 11 of measurement. The magnetic field can, therefore, be detected with high sensitivity and high resolution.

Title: Noise elimination circuit
Inventor: KATABE YUTAKA
IPC: H03K5/01
Filed: 1989-06-14
Abstract: PURPOSE:To reduce noise of a signal with one terminal per one signal by providing a signal processing circuit comparing a potential of an input terminal with 1st and 2nd threshold levels and outputting a potential in response to the level or change and providing a resistor between an output of the circuit and the input terminal. CONSTITUTION:A low level is outputted from an output terminal 14 of a signal processing circuit 13 when a potential of an input terminal 12 is lower than a 1st threshold level V1, and a high level is outputted when the level of the input terminal 12 is higher than a 2nd threshold level V2 (V1<V2). When the potential of the output terminal 14 is at a low level and the potential of the input terminal 12 changes from a potential lower than the level V1 to a potential higher than the level V1, the potential of the output terminal 14 changes to a high level. When the potential of the output terminal 14 is at a high level, the circuit is operated conversely and the potential of the output terminal 14 changes to a low level. Thus, the noise component of the input signal is reduced and when a noise elimination circuit is integrated, the noise component is reduced with one terminal per one signal.
