Abstract: PROBLEM TO BE SOLVED: To solve the problem that, in order to suppress partial electric discharge between an electrode at a surface side (surface electrode) and a back electrode when testing a power semiconductor chip applying a high voltage thereto, a jig made of insulating material is pressed against the chip, requiring that a jig size is changed depending on a chip size and hence requiring by-size management, and that, when sticking of a foreign matter, a flaw or deterioration occurs due to destruction marks of a defective chip, the jig made of insulating material requires replacement and, hence, incurs an increase in cost.SOLUTION: An insulating jig for suppressing electric discharges is constructed by forming a chip's termination structure part as a divided structure and providing two types of components, a component for corners used for the corners of the terminal structure part and a component for sides used for the sides. Also, the number of components for the sides is set to be changeable.
