  • Patent number: 8052810
    Abstract: A metal structure according to the present invention is unlikely to become brittle and has excellent hardness and creep resistance, characterized in that annealing has been applied at a temperature not more than the temperature at which crystals of the metal material start to become larger. This metal structure includes at least two kinds of metal material, and annealing can be applied at a temperature not more than the temperature at which crystals of the metal material start to become larger. For example, the present invention is advantageous in the manner of a microstructure for a contact probe. A fabricating method according to the present invention is a method of fabricating a metal structure unlikely to become brittle and having excellent hardness and creep resistance, characterized in that the step of applying annealing at a temperature not more than the temperature at which crystals of the metal material start to become larger is included.

  • 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.
