Abstract: High dielectric constant capacitors are made from a dielectric ink of lead-magnesium-niobate and lead oxide powders. Dielectric inks are made by mixing the dielectric powders with a suitable organic vehicle which can be used to coat one or more glass-based green tapes. Buried capacitors are made by coating an overlying and an underlying green tape with a conductor such as silver. Capacitors can also be made by adjusting the organic vehicle and forming a green tape from the dielectric powders. These dielectric green tapes each can be coated with a conductive layer and stacked, the conductive layers connected in parallel. The resultant multilayer capacitors have a very high dielectric constant, while eliminating the need for very large area capacitors, as compared to single layer capacitors.

Abstract: Large value embedded inductors are made by screen printing an inductor coil onto one or more ferrite tapes, and covering the ferrite tapes with one or more ferrite tape layer or layers. Low firing temperature green tapes surround the ferrite layer or layers. These green tapes can be expansion matched to gallium arsenide.
