SILICON CARBIDE CHIP, SILICON CARBIDE WAFER, TEST METHOD FOR SILICON CARBIDE CHIP, AND TEST METHOD FOR SILICON CARBIDE WAFER

摘要

PROBLEM TO BE SOLVED: To provide a silicon carbide chip, a silicon carbide wafer, a test method for a silicon carbide chip, and a test method for a silicon carbide wafer, to which a current conduction test can be applied even when a chip has a large area.SOLUTION: A silicon carbide chip 4 includes a product chip region 1 in which a silicon carbide semiconductor element performing an actual action is crated, and a PN diode 3 which is disposed around the product chip region 1 and which is not involved in an actual action of a smaller area than the product chip region 1.
