<title>High density packing and interconnections for hybrid microelectronics: new trends in materials development</title>

Electronic devices, components, circuits and microsystems continue to become smaller, lighter, faster and less expensive. The progress in hybrid microelectronics, especially in high density packaging and interconnections, is very much dependent on the achievements in developing new electronic materials. The paper presents the state of art of thick film materials as well as the new developments carried in Hybrid Mirocircuits and Microsystems Laboratory, which was established in 2006 by Warsaw University of Technology, Department of Electronics and Information Technology and Institute of Electronic Materials Technology.
