Abstract
A probe device, for performing an electrical test of a semiconductor device formed on a semiconductor wafer, includes a mounting table on which the semiconductor wafer is mounted, a driving mechanism configured to bring a probe into contact with an electrode of the semiconductor device mounted on the mounting table, and a temperature control mechanism configured to control a temperature of the mounting table. The mounting table includes a disk-shaped first electrode, a disk-shaped second electrode, and a disk-shaped insulating plate interposed between the first electrode and the second electrode. The first electrode, the second electrode and the insulating plate are fixed to each other at a fixing part provided at their respective centers, and are locked to be movable in a diametric direction at a locking part provided at an outer side of the fixing part in the diametric direction.
