Abstract: An apparatus and method for creating multi-layer embedded ceramic capacitors in low-temperature co-fired ceramic (LTCC) substrates. In order to create multiple layers of electrodes, the individual electrode layers must be connected electrically. According to the present invention, a multi-layer capacitor is formed on a first ceramic tape layer. A second tape layer having an opening is placed on top of the first layer. The opening in the second layer is formed such that exposed vias are present on at least two sides of the opening to electrically connect to the electrodes. When the tape layers are pressed and fired, the exposed vias and electrodes form common electrical connections. A third layer having a terminal via may be placed on top of the second layer.

Abstract: A method for providing an enhanced ball grid array attachment in low-temperature co-fired ceramic (LTCC) substrate is provided. A termination cup is formed in a substrate. The termination cup has a bottom formed by a termination pad over a via in a first tape layer and side walls formed by termination sides formed over side walls of a via in a second tape layer. A diffusion layer is formed over the termination cup. The diffusion layer helps to reduce the oxidation of the termination cup and to provide greater mechanical attachment strength. An electrically conductive adhesive may be used to connect a solder ball to the diffusion layer. Reflow then is used to complete the solder ball connection process.
