Y. Saitoh et al., DEVELOPMENT OF NOVEL FABRICATION TECHNIQUES FOR A SILICON MICRO-VERTEX DETECTOR UNIT USING THE FLIP-CHIP BONDING METHOD, IEEE transactions on nuclear science, 41(4), 1994, pp. 1192-1196
Full-size models of a detector unit for a silicon microvertex detector
were built for the KEK B factory. The Flip-Chip Bonding (FCB) method
using a new type anisotropic conductive film (ACF) was examined. The s
tructure using the new type ACF and improved fabrication process provi
de a sufficient electrical connection and good reliability for the det
ector unit.
