    摘要: A method of producing a contact structure and a probe card makes it possible to test a semiconductor integrated circuit device formed on a semiconductor wafer having a pin pitch of 0.5 mm or smaller. The contact structure includes a micro contact pin having electric conductivity formed on one end of a beam which is movable in a vertical direction, and a piezoelectric element formed on the beam to drive the beam in the vertical direction. The beam is made of silicon on the surface of which is formed of a conductive thin film, and the micro contact pin has a pyramid shape. The piezoelectric element is a bimorph plate mounted on an upper surface of the beam or both upper and lower surfaces of the beam.

    摘要: A micro contact structure and a probe card to be used in testing performance of a semiconductor integrated circuit device formed on a semiconductor wafer have improved contact characteristics. The contact structure includes a micro contact pin having electric conductivity formed on one end of a beam which is movable in a vertical direction, and a piezoelectric element formed on the beam to drive the beam in the vertical direction. The beam is made of silicon on the surface of which is formed of a conductive thin film, and the micro contact pin has a pyramid shape. The piezoelectric element is a bimorph plate mounted on an upper surface of the beam or both upper and lower surfaces of the beam.
