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.

ABSTRACTNext generation microelectronic packaging requirements are driving the need to produce increasingly lower dielectric constant materials while maintaining high thermal stability and ease of processing. Polymer candidates with exceptionally low dielectric constant (2.0-2.4), high thermal stability (degradation temperature higher than 400°C), high glass transition temperature (greater than 350°C), low water uptake (less than one percent), solubility in selected organic solvents, and low thermal expansion are all required. We have successfully synthesized and characterized several candidate polymers in an effort to address these needs.
