Abstract:
1. An operation voltage supply apparatus for a semiconductor device, which comprises: a voltage development device which includes: a variable voltage source and a voltage compensation circuit which includes: a voltage input terminal to which a set voltage set by said variable voltage source is inputted, an output terminal for outputting an output voltage to be applied to a voltage application pad of said semiconductor device, and a measurement input terminal for receiving a measurement voltage at a voltage measurement pad of said semiconductor device, said voltage compensation circuit providing a compensation voltage resulting from the sum of said set voltage and a different voltage between said set voltage and said measurement voltage to the semiconductor device through the voltage output terminal; and a probe card which includes: a voltage application probe for electrically connecting said voltage application pad and said output terminal and a voltage measurement probe for electrically connecting said voltage measurement pad and said measurement input terminal to measure the measurement voltage.
