Latest Patents:
Among his latest innovations are two noteworthy patents. The first, titled "Suppression of Crystal Growth in Low Dielectric Inorganic Composition," details a ceramic composition designed to form a dielectric body with a dielectric constant of less than about 5.0 and a thermal expansion coefficient (TCE) ranging from 2.0 to 4.0 ppm/°C. This invention utilizes a mixture containing 25-50 weight percent of low-temperature glass—selected from borosilicate and zinc borate glasses—and 50-75 weight percent of high-temperature glass, including high silica and titanium silicate glass. Additionally, the composition includes 1-10 weight percent of ceramic material with a particle size of less than 3 microns, with colloidal alumina being a preferred choice.
The second recent patent, "Devitrification Inhibitor in Low Dielectric Borosilicate Glass," offers a ceramic composition for forming a dielectric body that exhibits a dielectric constant of less than about 5.5 and a TCE of less than 5.0 ppm/°C. This innovative composition comprises 10-90 vol. % of borosilicate glass combined with a material like Ga2O3 or other gallium-containing compounds to prevent the crystallization of silica. This product can also be combined with a polymeric binder to create unfired green tape that can be co-fired with conductive metallurgies, including gold and silver.
