A nowadays market demands for advanced MEMS encourages producers to extensive research aimed at improvement of production yield and at increase a devices reliability. In the case of vacuum MEMS that employ getter technology for vacuum enhancement, and increased production yield, the development of anew individual process flow is very complex. In particular, the adaptation of the equipment for packaging process becomes a grate challenge where computer-aided development and virtual modelling appears tremendously helpful. The implementation of new approach for a Chip to Wafer (C2W) bonding is one of main goals of the European project DAVID realised in frame of EU-FP6. In this paper Authors report the implementation of a Finite Element Method (FEM) in modelling the heat flow and deformation of bonding machine main parts in order to improve the technology for hermetic vacuum bonding and in particular to develop the bonding machine itself.
