Abstract:
1. A probe block for a probe card of a semiconductor test device, comprising: a guide member having pairs of upper and lower holes and middle holes each interconnecting the upper and lower holes of each pair; and a plurality of probes each comprising a first pin tip protruded through a corresponding upper hole and a second pin tip protruded through a corresponding lower hole and a bridge part situated within the middle hole for interconnecting the first and second pin tips, wherein at least one of the first pin tip, the second pin tip, and the bridge part is substantially flat, and at least one of the first pin tip and the second pin tip extends substantially straightly, wherein the upper, lower, and middle holes allow the probe to elastically moves in vertical direction, wherein a width of the middle holes is greater than a width of the upper holes and than a width of the lower holes, each of the middle holes being defined by a first horizontal surface, a second vertical surface, and a third horizontal surface, and wherein the bridge part includes a first bridge part extending substantially along the first horizontal surface of the middle hole, a second bridge part extending substantially along the second vertical surface of the middle hole, and a third bridge part extending substantially along the third horizontal surface of the middle hole.
