Latest Patents

DiLazzaro's latest patents include innovations in low dielectric constant ceramic materials. One patent describes a dense, sintered ceramic material that features a low dielectric constant, low firing temperature, and low coefficient of thermal expansion. This material is created from a mixture of 0-30 wt. % alumina, 30-60 wt. % fused silica, and 30-70 wt. % of a glass composed of PbO, B.sub.2 O.sub.3, and SiO.sub.2. The minimum sintering temperature for this mixture ranges from 800°C to 900°C, making it suitable for conventional manufacturing techniques. This invention is particularly useful for fabricating single or multilayer electronic circuit substrates. Another patent focuses on low firing temperature ceramic materials, which also exhibit a low dielectric constant and low coefficient of thermal expansion. This material is derived from a mixture of 10-50 wt. % alumina, 0-30 wt. % fused silica, and 50-60 wt. % of a frit made up of CaO, MgO, Al.sub.2 O.sub.3, B.sub.2 O.sub.3, and SiO.sub.2. The minimum sintering temperature for this mixture is between 850°C and 1000°C, and it can also be produced using conventional manufacturing methods.
