Patent ID: 8659312

Claim:
A probe card, which is formed on a semiconductor wafer and collectively inspects a plurality of semiconductor chips each having a plurality of pad electrodes, the probe card comprising: a thin film substrate having a plurality of projection electrodes on a first surface facing the semiconductor wafer and at a position facing each of the pad electrodes, a non-contact electrode to be electrically connected to the pad electrodes by capacitive coupling or inductive coupling, and a plurality of first electrodes provided on a second surface opposite to the first surface and electrically connected to each of the projection electrodes and the non-contact electrode; and a wiring substrate having a plurality of second electrodes disposed at a side opposite to the semiconductor wafer in the thin film substrate and at a position facing the first electrodes, wherein the wiring substrate and the thin film substrate form a first sealed space and the thin film substrate and the semiconductor wafer form a second sealed space; by reducing the pressure in the first sealed space and the second sealed space, the first electrodes and the second electrodes are brought into close contact with each other and the pad electrodes and the projection electrodes are brought into close contact with each other; and the pressure of each of the first sealed space and second sealed space are independently adjusted.
