Abstract:
1. A method of fabricating a probe array, comprising: forming a mold insulating layer on a sacrificial substrate; first patterning the mold insulating layer, thereby forming first holes exposing the sacrificial substrate; forming a first conductive layer on the sacrificial substrate having the first holes; first planarizing the first conductive layer, thereby forming first probes arranged two-dimensionally in row and column directions on a sacrificial substrate; second patterning the mold insulating layer, thereby forming second holes exposing the sacrificial substrate; forming a second conductive layer on the sacrificial substrate having the second holes; second planarizing the second conductive layer, thereby forming second probes between the first probes arranged in the row direction; forming a probe substrate above the first and the second probes; and removing the sacrificial substrate.
