Background

The probe card is an important technology in the chip manufacturing process, before the chip is packaged, the probe on the probe card is directly contacted with the welding pad or the lug on the chip, the chip signal is led out, and then the automatic measurement is realized by matching with a peripheral test instrument and software control, so that the defective product is screened out, and the product yield is ensured.

With the development of micro-electro-mechanical systems (MEMS) technology, the size of a chip is smaller and smaller, and reaches millimeter level, and the integration level inside the chip is higher and higher, and reaches micron level, even submicron level, which requires the volume of a probe card to be reduced along with the probe, so that the probe manufacturing faces new challenges.

Therefore, from the beginning of the new century to the present, various national scholars and various enterprises make extensive trials and innovations in probe card manufacturing, and strive for probe cards to meet the test requirements of semiconductor devices along with the development of semiconductor technology.

Among these techniques, there are some for manufacturing a probe card with a larger size, and some for avoiding needle burning during a test, and although there are also techniques for manufacturing a probe card with a higher integration, it is still impossible to realize a probe card with a probe size in a sub-micron order. The reason is that, for the probe with the size of submicron order, the bending of the probe cannot be effectively avoided in the manufacturing process, and once the probe is slightly bent, the probe will contact another probe with the distance of submicron order, which causes the manufacturing failure.
