IPC: G01R31/28
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To enable an IC testing device to test ICs at exact timing without increasing the scale of the device by impressing test signals stored in registers upon test heads when timing pulses outputted from counters coincide with the impressing timing information of the test signals. SOLUTION: When timing pulses for actuating test units 20-1 to 30-n are outputted from a timer unit 20, counters 32-1 to 32-n counts the pulses and output the count values to coincidence circuits 33-1 to 33-n. The circuits 33-1 to 33-n compare the timing pulses with test signal impressing timing information for a test head 40 stored in registers 31-1 to 31-n and, when the pulses coincide with the information, the units 30-1 to 30-n output 'ON' signals to the test head 40. Therefore, DUTs (ICs) 41 can be tested at exact timing without increasing the software load of a CPU 11 and the hardware scales of the units 30-1 to 30-n.

Title: Semiconductor switching device
Inventor: TERASAWA YOSHIO
IPC: H01L21/8222
Filed: 1987-12-09
Abstract: PURPOSE:To perform switching operations at a high voltage with a large electric current by forming a GTO thyristor and an ASO transistor at a low ON voltage in a sheet of semiconductor substrate in accordance with completely the same process as that used in the case of forming the GTO thyristor only. CONSTITUTION:A p-type base layer 8 of a GTO thyristor which is formed simultaneously with the formation of the p-type base layer 11 has a low concentrated impurity and is formed so that it may have thin parts, because it is formed by depositing partially the p-type impurity. That is to say, as the p-base layer 8 is formed by depositing partially the p-type impurity, a thin p-type impurity region is formed at the lower part of a part where the p-type impurity is not placed and it is constructed as well by forming the p-type impurity region where an impurity concentration is low. Having the p-type base layer 8 in this way, the GTO thyristor facilitates injection of electrons towards an n-type base layer by a semiconductor substrate 7 from an n-type emitter layer 9 through this p-type base layer 8 and develops into other GTO thyristor where TURN-ON operations are quick and its ON voltage is low.

IPC: H01L29/84
Filed: 1989-11-28
Abstract: PURPOSE:To suppress inside-outside pressure difference due to the expansion and contraction of damper oil by using shape memory alloy for an outer peripheral cap for charging damper oil at the periphery of a semiconductor sensor in cantilever structure. CONSTITUTION:The bellows type outer peripheral cap 8 is mounted on a base plate 1 while surrounding the cantilever 3 of an Si chip.
