ABSTRACTThe need for low dielectric constant, high thermal conductivity, matched thermal expansion and co-processability in electronic substrates is reviewed. Since no single phase material is able to satisfy all the requirements, a microscopic composite approach is proposed. Recent experimental evidence supporting the concept is also presented.

In this work, we propose a new model for the dielectric constant and thermal conductivity, and apply it to the design of composites with low dielectric constant and high thermal conductivity based on fractal theory and effective medium theory. In particular, we use this model to prepare porous AlN/BN/SiOC composites with low dielectric constant and high thermal conductivity in different component fractions. We successfully synthesize ceramic samples with low dielectric constants [Formula: see text] and high thermal conductivity ([Formula: see text]). These results indicate that the proposed fractal design is valid.

AbstractA variety of low dielectric constant composites have been made into films and characterized. These composites were blends of liquid crystalline polymers (LCPs), hollow glass spheres (HGS) and polytetrafluoroethylene (PTFE). By adjusting the percentage compositions of the various components of the composites, the dielectric constant could be adjusted in the range 2.4 to 3.4. Measurement of the dielectric constant by Time Domain Reflectometry (TDR) and Frequency Domain Reflectometry (FDR) are discussed. Dielectric anisotropy is also discussed. The experimentally observed results are compared with those derived theoretically.
