The material may also contain an element with valence 2 such as magnesium and zinc. Transition metal dopants can also be added to reduce annealing time and/or to tune the temperature-coefficient of resonant frequency. The dielectric material can be made in ceramic or thin film form. The process begins with a mixture of barium carbonate, zinc oxide, tantalum oxide, and cadmium oxide blended together. The slurry is dried and heated. A sintering agent is added to produce high-density samples. The resulting slurry is dried and an adhesive is added to press the mixture into a solid ceramic samples. Thin film dielectric material is made with a thin film growth technique, such as by exposing the mixture to a laser and growing the material on a substrate.Type: ApplicationFiled: June 30, 2003Publication date: October 7, 2004Inventors: Nathan Newman, Mark van Schilfgaarde, Shaojun Liu, Jihoon Kim
