INTERPOSER, PROBE CARD AND METHOD FOR MANUFACTURING INTERPOSER

摘要

Disclosed is an interposer comprising a silicon substrate (20). A plurality of conduction holes (27) penetrating the silicon substrate (20) are formed by dry etching, and at least one end of each conduction hole (27) is provided with a probe (12) via a pad (45). Since conduction holes are formed in a substrate which can be processed by dry etching, a plurality of fine conduction holes can be continuously formed and a probe can be connected to each conduction hole. Consequently, there can be obtained an interposer wherein probes are arranged at high density.
