Abstract :
MID technology offers a very interesting alternative for many applications in MEMS and MOEMS suitable for multifunctional 3D packages due to its high capability in miniaturization as well as in reducing the number of components and process steps. To make use of the full potential of MID technology not only SMD assembly has to be considered but also mounting of bare dies. For flip chip mounting MID technology offers a unique assembly solution consisting of polymer bumps (MID bumps) fabricated simultaneously while moulding the substrate. In this paper investigations of the mechanical and geometrical properties and the deformation behaviour of metallized polymer bumps for flip chip assembly are described
