Semiautomatic measurements of thin-film breakdown voltages

Rev Sci Instrum. 1979 Oct;50(10):1218. doi: 10.1063/1.1135689.

Abstract

A semiautomatic setup is described which provides the destruction-free measurement of breakdown voltages of thin-film structures for applications like process control and quality prediction. The method of measuring the breakdown voltage consists in feeding a constant current to the thin-film device and analyzing the voltage buildup across the device. This method has been described in a recent paper. The setup provides the successive analysis of breakdown behavior of a given matrix of wafer dots by means of a positioning table, an electropneumatic prober, and a microprocessor-controlled measurement unit via handshake commands. The results are given in a histogram form.
