Objective The project is dedicated to investigate and to develop a technology of flexible multilayer hybrids and flexible interconnecting elements based on thin film microcables with aluminum traces. Such innovative devices are necessary to assemble full scale modules of silicon coordinate detectors for the inner tracking system (ITS) of the ALICE (A Large Ion Collider Experiment) detector at CERN (European Organization for Nuclear Research), presently under preparation for construction. The considerable dimensions of the ITS make it impossible to transfer the signals coming from the silicon sensors far from the sensitive volume before electronic treatment. In practice, the front-end electronics including amplifier and multiplexer (and, for the Silicon Drift Detectors, also analogue to digital conversion) should be placed in the absolute vicinity to the detector planes. The ITS layers are required also to be 100% efficient, and therefore to leave no 'dead-space' between sensitive detector elements. Therefore the detectors are positioned overlapping each other at small distance and the hybrids and interconnections must allow for complex geometrical arrangements in space. These restrictions together with the necessity to provide the inter component connections between the double-sided detectors and specific hybrids excludes the possibility to use wire bonds.It is suggested to use the film aluminum microcables created as flexible interconnections for direct electrical contacts by bonding of all detector module elements increasing the mechanical ruggedness of the module and simplifying the assembly procedure.Following the proponents experience in the development of flexible microcables, created in several years of R&D, the proposed program aims at the extension of this approach to high voltage (few kV) low-mass interconnections and flexible hybrids integrating electronic components.The proposed program also includes the necessary computations and simulations required to asses the influence of the proposed solutions on the physics performance of the tracking system of the ALICE experiment at the LHC, including both specific physics signals and device simulations.
