Patent ID: 7548082

Claim:
An inspection probe for inspecting electrical properties of a semiconductor device, comprising: a base member; wiring layers mounted on the base member; probe pins having tips, electrically connected to the wiring layers, protruding from the base member; first metal layers provided to the tips of the probe pins; second metal layers formed on the wiring layers, the second metal layers being made of a material different from that of the probe pins, the second metal layers physically separated from the first metal layers by the probe pins; a flexible, electrically connectable wiring substrate placed between the base member and a inspection substrate and a backup plate mounted on the inspection substrate, for mounting the base member thereon if the electrodes of the semiconductor device are arranged at sides thereof, correspond to multiple pins, and must be connected to the inspection substrate; and a support substrate which is integrated with peripheral portions of the base member with an adhesive member placed therebetween and which is made of the same material as a material of the base member, said support substrate being mounted on the inspection substrate, wherein the backup plate has a protrusive portion at a center area thereof such that the probe pins form a predetermined angle with respect to the electrodes of the semiconductor device.
