  • Patent number: 7208964
    Abstract: It is an object of the present invention to provide an arch type probe capable of enduring a load caused by overdriving even if the probe is miniaturized, and a probe card using the same. An arch type probe 200 has a shape including a first quarter circle arc portion 210 which is supported at one end thereof by the base plate 100 and a second quarter circle arc portion 220 which is connected to the other end of the first quarter circle arc portion 210, extending toward the base plate and a little shorter than the first quarter circle arc portion 221. The top portion of the arch type probe 200 serves as a contact surface brought into contact with an electrode of a semiconductor water B.

  • Patent number: 6980013
    Abstract: A probe card including rectilinear probes; a guide base plate having an insulating property, in which a plurality of guide holes are formed through which the probes are inserted in a freely movable manner and a length of a guide hole is shorter than a length of a probe; and a plurality of sheet members having an insulating property, disposed above the guide base plate facing the plate, and laminated one on another with a spacing therebetween so as not to be in contact with one another. The tail ends of some of the probes can be brought into contact with the electrode pads on a lowest sheet member, and the tail ends of the other probes penetrate through the lowest sheet member so as to be enabled to be in contact with electrode pads on other sheet members.
