Title: Voltage measuring apparatus, voltage measuring method and measuring apparatus for semiconductor element
Inventor: MATSUMOTO KEI
IPC: G01R31/30
Filed: 2000-09-22
Abstract: PROBLEM TO BE SOLVED: To deal with measurement results up to dielectric breakdown in a unified way for test samples having different serial resistance components. SOLUTION: As increasing an external voltage V in the region where the current passing though a semiconductor element follows to the formula of Fowler-Nordheim tunnel current until a predetermined voltage in which a parastic resistance except in an insulation film is negligible, the external voltage V and the current i are measured. Then, based on the measured V and the i, an ideal curve 109 is found out by the calculation of Fowler-Nordheim tunnel current of the semiconductor element. As increasing the current i with a predetermined step ratio from the current corresponding to the predetermined voltage, i and V are measured in each step. If V decreases suddenly, the current is defined as a dielectric breakdown current in which a dielectric breakdown shown by a line 108 has occurred.  The dielectric breakdown voltage corresponding to this dielectric breakdown current, namely, the voltage Vbd3 in the intersection point of the curve 109 and the linear 108 is calculated by the formula of Fowler-Nordheim tunnel current.
