Abstract:
1. A method of manufacturing a probe card comprising: providing a substrate and forming a first inactivation layer on the substrate; forming a first patterned photoresist layer on the first inactivation layer; forming a first metal layer on the first inactivation layer and the first patterned photoresist layer, wherein the first metal layer has a plurality of first through holes exposing a portion of the first patterned photoresist layer, and a diameter of the first through holes gradually increases from a lower surface of the first metal layer to an upper surface of the first metal layer; forming a second inactivation layer on the first metal layer and the first patterned photoresist layer; forming a second patterned photoresist layer on the second inactivation layer, wherein the second patterned photoresist layer has a plurality of second through holes exposing the first through holes; forming a plurality of pins inside the second through holes and the first through holes and forming a second metal layer on the second patterned photoresist layer such that one end of the pin connects with the second metal layer; taking out the pins and the second metal layer; providing a circuit carrier, wherein the circuit carrier has a plurality of third through holes, and the pins are inserted into the third through holes; and patterning the second metal layer to form a plurality of pinheads such that each pinhead connects with one of the pins.
