Abstract : In the field of power hybrid integration, it is well known that wiring operation of power semiconductor devices is a source of strong parasitic electrical interactions between interconnections parasitic inductances, parasitic capacitances with respect to the ground plane, the power semiconductor devices themselves and the electronic control circuit. These interactions are a source of EMI on one hand and a factor limiting the performance and reducing the reliability of the power function on the other hand. Monolithic power integration is obviously the only approach to overcome some drawbacks of the hybrid integration. In this context, this thesis work studies the feasibility of a monolithic integration approach called "dual-chip". This power integration approach deals with the integration of the generic power converter circuit (AC/DC or DC/AC for low and medium power applications) in two complementary multi-switch power chips: A common anode/back-side multi-switch chip, and a common cathode/front-side multi-switch chip. The study includes: modeling by 2D physical/electrical simulations of the proposed structures, validation of their operating modes, realization of the chips in the micro and nanotechnology platform of the LAAS, electrical characterization of the chips and finally a study of 2D and 3D association techniques of the realized chips on SMI/DBC substrate. The scientific perspectives of this work are based on a promising integration approach called "single-chip". The resulting single-chip corresponds to the fusion of the two power chips used in the first approach and takes advantage of the conclusions made from their association techniques study.
