Design aspects as well as a suitable packaging concept and technology will be highlighted. The value of accompanying FEM simulations together with the usage of novel reliability tools will be demonstrated as a design and construction accelerator that can help to avoid typical mistakes within the material selection and concept phase of a MEMS fabrication process. We will give an introduction for suitable wafer-levelbonding methods for multilayer stacking of functional substrates especially for the heterogeneous integration of silicon and low temperature co-fired ceramic LTCC (low temperature co-firing ceramic). The fabrication process for LTCC with electrical feed troughs and for Silicon substrates with through silicon vias TSVs (through-silicon via) and a subsequent electrical interconnection between both will also be topics of this work.enconference paper
