The utility model discloses a passive circuit coupled annular ring-type tellurium cadmium mercury chip. An annular ring is employed to couple a tellurium cadmium mercury chip on a passive circuit, namely when a ion beam etches the annular ring, a cylindrical N-on-P node is formed around an interconnection aperture, so as to realize interconnection of an n-type zone with the passive circuit through metallization of the annular ring. The utility model has the advantage that the chip can connect with a playback circuit through spun gold interconnection, and not only overcomes the problem of spun gold covering a photosensitive surface, but also can separate the detector chip and the playback circuit to increase yield of the focal plane; besides, the utility model performs the advantages of the annular ring-type detector, and has simple technology and high fill factor. |
