Patent ID: 8314624

Claim:
A method of manufacturing a semiconductor device comprising the steps of: providing a semiconductor wafer to which circuits and electrodes electrically connected to the circuits are integrated and a plurality of semiconductor elements are formed; and inspecting electrical characteristics of the plurality of semiconductor elements using a probe card having a plurality of contact terminals contacting with the electrodes provided on the plurality of semiconductor elements, and being electrically connected to a tester for inspecting electric characteristics of the circuits formed on each of the plurality of semiconductor elements, wherein the probe card includes: a probe sheet comprising: a main surface, a rear surface located on a reverse side of the main surface, the plurality of contact terminals formed on a main surface side for contacting with electrodes provided on the plurality of semiconductor elements, a plurality of wires drawn from each of the plurality of contact terminals, and a plurality of peripheral electrodes electrically connected to the wires and electrodes of a multi-layered wiring board; a frame formed so as to surround the plurality of contact terminals; a first pressing portion for providing a pressing force from a rear surface side of the probe sheet via a pressing piece to a region in which the plurality of contact terminals of the probe sheet are formed; a second pressing portion for providing a pressing force to the rear surface side of the probe sheet via the frame, the second pressing portion including a plurality of guide pins with a spring property and a plurality of guide pins without the spring property; and a coupling portion for coupling the first pressing portion and the second pressing portion, wherein the coupling portion and the pressing piece are not in contact with each other; and while the pressing force is imparted to the region, where the plurality of contact terminals are formed, of the probe sheet held so as to protrude from the multi-layered wiring board via the frame, the plurality of contact terminals are brought in contact with the electrodes provided on the plurality of semiconductor elements so that the electrical characteristics of the circuits are inspected.
