Definitions
- the present invention relates to a conductive contact holder suitable for a conductive contact unit used in a semiconductor-related component inspection process.
- a burn-in test is performed in which a voltage is applied under a high-temperature atmosphere (about 150 degrees) for a long time (several hours to several tens of hours). Due to poor yield in testing, higher yields are required by performing burn-in tests at wafer level (eg, 200 mm diameter wafers). Therefore, a conductive contact unit that can measure multiple points simultaneously is used for the wafer-level burn-in test.
- the individual conductive contacts used in the conductive contact unit preferably have a structure in which conductive needles are resiliently contacted with the contacted object to allow for variations in electrode height on the wafer.
- An example is shown in FIG. In the figure, a stepped hole-shaped holder hole 2 penetrating in the thickness direction is formed in the plate-like support 21, and the conductive needle-shaped body 23 is formed by the small-diameter hole 2 a of the holder hole 2.

- One end of the coil is elastically urged by a coil spring 24 wound around a shaft 23 b extending from a. Note that the other coil end of the coil spring 24 is in spontaneous contact with each terminal 25 a of the wiring board 25 laminated on the support 21. These terminals 25a are connected to an electric circuit of a tester (not shown).
- the conductive contact of the above structure is arranged in parallel on the support 21 to enable simultaneous measurement at multiple points.
- a conductive contact unit is configured. Then, the tip of each conductive needle-shaped body 23 of the conductive contact unit is pressed against each electrode 26a of the wafer 26 (inspection object) as a contacted body, so that a wafer unit is formed. Electrical inspections can be performed at

It has been done. By doing so, the strength of the support body 28 provided with the reinforcing material 27 is increased, so that the above-described displacement can be prevented.
- the overall length (the length of the signal line) should be reduced, but the thickness of the support (the axial length of the conductive contact) will also be reduced. As a result, if the support becomes thinner and the reinforcing material becomes thinner, there arises a problem that the strength of the support decreases.
- the above-mentioned reinforcing material is simply formed by insert-molding synthetic resin.
- the thickness of the synthetic resin material covering the reinforcing material is increased to some extent.
