IPC: H01L21/66
Filed: 1991-04-15
Abstract: PURPOSE:To enable the contactless test of transistors by moving a measurement electrode counterposed to the measurement plane of an electrode or a wiring of a transistor under test to vary the gap between the measurement plane and the measurement electrode. CONSTITUTION:A measurement electrode 1 is counterposed above a wiring 106 at a distance L. A potential is impressed on a source electrode 104: a gate electrode 103 is turned on or off in this state to measure the potential of the wiring 106 connected to a drain electrode 105 for comparison with the potential impressed on the source electrode 104. The measurement electrode 1 is displaced as it remains at 0V, and a current accordingly flowing through the electrode is detected by a current detector 3 to calculate the total quantity of current so that the quantity of charges irradiated between the wiring 106 and the measurement electrode 1 is determined to obtain a potential of the wiring 106.
