Front-end modules for ALICE SSD

Two kapton/aluminum hybrids supporting the FEE provide a good radiation length whereas Tape Automated Bonding (TAB) using kapton/aluminum microcables connects sensor, FE chips and hybrids without using any wire bonding.These flexible connections allow folding the FEE over the sensor, providing a compact detection module and the decoupling of the geometrical position from the liquid cooling means.Figure 1 shows one of these modules in an unfolded position, with the sensor in the middle and with the top hybrid connected to the upper side of the sensor and the bottom hybrid connected to the hidden side of the sensor.One can notice the flexible so-called chip-cables connecting sensor and FEE.The Silicon Strip Detector (SSD) front-end module will populate the two outer layers of the ALICE inner tracker.After years of design and developments reported in the previous proceedings of the LECC workshop [1], [2], [3], several working prototypes of this module have been produced with the final components in two different laboratories.The first test results will be presented.
