(57) [Abstract] Passive elements such as capacitors, resistors and RF filters are formed by screen-printing a suitable ink on green tape, with conductive layers (14 and 15) above and below the component ink layer. Can be completed. Next, the obtained green tape laminate is fired to form an embedded capacitor. By laminating the green tape laminate on a metal support substrate, shrinkage in the x and y dimensions is limited and the components can maintain close tolerances. When multiple green tape layers are laminated, a green tape having a suitable amount of oxidizing filler, for example, less than about 15% by weight of the green tape composition, may be replaced by a higher amount, for example, more than 25% by weight of oxidizing filler. When alternated with green tape having fillers, improved shrinkage is obtained. |
