Abstract
The capacitor on a ceramic substrate one by unique film metallization including in one embodiment an in situ oxidation of titanium to create a metal oxide capacitor. The combination of metals when used with the appropriate optimized oxidation conditions and parameters ensures a high yielding capacitor with high capacitance in absence of noble metals and with ease of manufacture providing a low cost, high yield capacitor on ceramic.
