摘要:
A bimorph switch electrically connecting a traveling contact and a fixed contact. The switch comprises a substrate having a front face, a rear face, and a through hole penetrating from the front face to the rear face; a fixed contact extending from an edge portion of the aperture of the through hole towards the inside of the aperture; and a bimorph section holding the traveling contact at a position facing the aperture and driving the traveling contact. One end of the bimorph section may be formed on a silicon oxide layer formed on a front face of the substrate.

The present invention provides a probe chip and a probe card in which when troubles such as breakage etc. occur in a probe of a contact portion of a probe card, the contact portion can be easily replaced with another one. In the probe card having a guide frame, a probe chip and a fixing jig, a second arm portion of a cantilever of the probe chip is abutted on a conductive path of a fixing jig such that the probe chip is held or pressed down and fixed to the guide frame with the second arm portion being elastically deformed.

A probe card transmits high frequency signals between an integrated circuit under test and a semiconductor-testing device. The probe card includes a substrate, a signal transmission path formed on the substrate, a contactor formed on an end portion of the signal transmission path on one side of the substrate, a grounding conductor grounded, and a hole. The contactor is made of a metallic glass material, which shows a nature of viscous fluidity in the supercooled liquid region. The contactor is separated from the substrate over the hole. The contactor elastically contacts a pad of the circuit under test.
