摘要:
A probe card includes a plurality of probes that contacts a plurality of electrodes provided in the semiconductor wafer and that inputs or outputs an electrical signal in or from the electrodes, a probe head that holds the probes, a substrate having a wiring which is provided near the surface of the substrate facing the probe head so as to be contactable with the probe head and is connected to the probes, a core layer formed of a material which is buried in the substrate and has a coefficient of thermal expansion lower than that of the substrate, and a connecting member that electrically connects at least some of the probes with an external device via the wiring.
