Abstract
A testing method is provided for a semiconductor device which includes a control terminal and a pair of main terminals wherein one of the main terminals is isolated from the outside by a dielectric. First, a voltage which changes with time is applied to the isolated main terminal through the dielectric. A control signal which controls conduction and non-conduction of the semiconductor device is the applied to the control terminal. Following this, the test is made by detecting a displacement current flowing through at least one of the two main terminals and the control terminal.
