Zusammenfassung:A substrate for radiofrequency microelectronic devices comprises a carrier substrate made of a semi-conductor, a sintered composite layer disposed on the carrier substrate and formed from powders of at least a first dielectric material and a second dielectric different from the first material, the sintered composite layer having a thickness larger than 5 microns and a thermal expansion coefficient that is matched with that of the carrier substrate to plus or minus 30%.
