Title: Measuring method of radiation dose in semiconductor integrated circuit
Inventor: HOSHI TOSHIHIRO
IPC: G01T1/167
Filed: 1979-02-09
Abstract: PURPOSE: To readily measure the radiation dose in an integrated cricuit by applying reverse bias to a pn-junction of a semiconductor integrated circuit through an external terminal and counting the number of pulses having predetermined amplitude contained in the leakage current flowing through the pn-junction.  
     CONSTITUTION: When α-rays 10 are irradiated on a MOSIC, electron(-) and hole(+) of a pair are generated on the trace of the α-ray. The VBB terminal T 3  of such a MOS memory is connected to ground potential through a resistor R. When the other terminal is connectd to a power supply +V, a reverse voltage is applied to the junction, and only the leakage current of the junction is flown through the circuit. Both ends of the resistor R are connected ot an amplifier. The output from the amplifier is compared with the standard voltage 11 by a comparator. The output from the comparator is applied to a counter circuit having flip-flops. When the α-rays 10 are irradiated on the junction in the circuit of n-MOS memory, a voltage change of several μV varies across the resistor R to thus detect the α-rays.

Title: Field effect transistor type inverter circuit
Inventor: SHIMIZU SHOICHI
IPC: H03K19/017
Filed: 1986-01-27
Abstract: PURPOSE:To execute an inverter operation at a high speed by using a transistor of an enhancement type, as a transistor whose drain is connected to a positive power source node. CONSTITUTION:As for the third transistor TR Q3' of a positive power source VDD side in an output stage buffer circuit, that of an enhancement type of N channels is used. When an input node 3 is in a high level (when a TR Q2 and a TR Q4 have become an on-state), the TR Q3' goes to an off-state entirely by a gate-source potential VOS=0V. Therefore, when the TR Q4 goes to an on-state, charge which is charged to a gate capacity of a TR Q6 before that time is discharged by the maximum current capacity of the TR Q4. Also, by discharging the charge which is charged to the gate capacity of the TR Q3', by the TR Q2, it can be operated at a high speed. Accordingly, an inverter operation can be executed at a high speed.
