CIRCUIT AND METHOD FOR MEASURING MICROVOLTAGE, AUTOMATIC APPARATUS AND METHOD FOR MEASUREMENT

摘要

PURPOSE: To obtain an automatic apparatus and method for measurement to be used for an insulation test and the like of a semiconductor device, in particular, and a circuit and method for measuring a microvoltage which enable attainment of the above apparatus and method, regarding an apparatus and method for testing a reed switch. ;CONSTITUTION: A pulse voltage generating means 1A for supplying a current to an object 3A to be measured which has a capacity component CS, a contactor 4A coming into contact with the object 3A, a minute voltage detecting means 1C which detects a microvoltage ΔV outputted from the object 3A, and a control means 1B which controls input/output of the pulse voltage generating means 1A and the microvoltage detecting means 1C, are provided. A construction is so made as to include comparison of the microvoltage ΔV with a reference voltage VS by the microvoltage detecting means 1C.;COPYRIGHT: (C)1993,JPO&Japio
