Title: Method for estimating service life of semiconductor device
Inventor: ERIGUCHI KOUJI
IPC: G01R31/26
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the service life of a semiconductor device can be estimated with higher accuracy in a shorter time. SOLUTION: A constant α is decided from an equation, T1 α+log(t1)}=T 2 α+log(t2)}, by measuring the time t1 and t2 at which a semiconductor device becomes unusable by performing stress tests on the semiconductor device at two or more different substrate temperatures under a certain electrical stress condition. Then the time (t) at which the semiconductor device also becomes unusable is measured by performing stress tests on the device under a different electrical stress condition and the relation between the amounts of the electrical stresses and the product, T α+log(t)}, is plotted in a graph so as to estimate the service life of the semiconductor from the graph.  Since the service life of the device in every possible environment is estimated from one graph based on accelerated test data, the service life can be estimated with higher accuracy in a shorter time by using the minimum number of measuring points.
