Abstract:
A method for analyzing an electrical contact between different component members incorporated in a semiconductor device, comprising the steps of:a) conceptually dividing said contact into a set of N regional elements each representative of a line or a region forming a part of said contact, where N is a natural number greater than 2;b) preparing sample devices, containing component members including at least said electrical contact, with the size of the regional elements varying amongst the samples;c) fitting the current passing through said contact to the following equation as a linear function of R.sub.k under a fixed biasing condition ##EQU5##where I is said current, R.sub.k is a length of said line or an area of said region, and the fitting parameter J.sub.k is a current density passing through said regional element represented by R.sub.k ; and thusd) determining current components J.sub.k of said current respectively each passing through said line or said region so as to analyze said contact.
