  • Patent number: 4852227
    Abstract: A green-ceramic parent substrate having buried therein a stack of spaced-apart sheet electrodes, each electrode having multiple tab portions extending in one direction to a plane that is orthogonal to the sheet electrodes and to the one direction. A row of holes is drilled between the tabs and through the ceramic in that plane. A plurality of elemental capacitor substrates are cut from the parent substrate, the cutting including dicing through the row of holes so as to leave a castellated edge in each elemental capacitor substrate. The elemental substrates are then fired to maturity and the castellated edge touched to a reservoir of a conductive paste and heated to form spaced apart conductive terminals contacting tabs of the buried electrodes at only the edge castellations.
