Abstract:
1. An operation voltage supply method, comprising the steps of; setting a set voltage of a variable voltage source of an operation voltage supply apparatus below 3.3 V; contacting a voltage measurement probe of a prove card of the operation voltage supply apparatus with a voltage measurement pad of a semiconductor device, said voltage measurement probe including a first end electrically connected to an output terminal of the probe card and a second end electrically connected to the first end of the voltage measurement probe; contacting a voltage application probe of a prove card of the operation voltage supply apparatus with a voltage application pad of the semiconductor device, said voltage application probe including a first end electrically connected to an input terminal of the probe card and a second end electrically connected to the first end of the voltage application probe; and supplying an operation voltage to the voltage application pad of the semiconductor device from the operation voltage supply apparatus.
