ABSTRACT:
A structural configuration and manufacture method is applied to manufacture electronic circuits on a ceramic substrate including capacitor and inductors for filters. The electronic circuits have strong bonding to securely adhere to the SOG-coated substrate when the SOG is cured at an elevated temperature supplemented with high nitrogen flow during the curing process. The SOG coated ceramic substrate shows excellent layer compatibilities during temperature variations because reduced differences of thermal coefficients between different layers.
