Abstract :
Full-size models of a detector unit for a silicon microvertex-detector for the KEK B factory are built. The model consists of four dummy double-sided, double-metal silicon microstrip detectors and two silicon end boards with dummy readouts VLSIs mounted on both sides. In this trial the flip-chip bonding (FCB) method, using an anisotropic conductive film, is applied to both sides of the detector unit to bond 640 strips at a pitch of 50 μm. The structure using the FCB method successfully provides a new architecture for the detector unit of a vertex detector
