Patent ID: 8114303

Claim:
A method of manufacturing a ceramic probe card, the method comprising: preparing a ceramic laminated body comprising a plurality of ceramic green sheets, said ceramic green sheets comprising ceramic powder, and an interlayer circuit comprising a conductive via and a conductive line formed in the plurality of ceramic green sheets; forming at least one probe pin structure connected to the interlayer circuit by forming a plurality of photosensitive ceramic sheets necessarily comprising ceramic powder identical to the ceramic powder comprised in the ceramic green sheets and a photosensitive organic component on the ceramic laminated body, selectively removing the plurality of photosensitive ceramic sheets, and by filling a metal material in a region from which the plurality of photosensitive ceramic sheets have been removed; and providing a ceramic substrate comprising the at least one probe pin structure by simultaneously firing the ceramic laminated body and the photosensitive ceramic sheets, and by removing the photosensitive ceramic sheets.
