A method for making multilayer ceramic capacitors (MLC) has two phases, namely a first test phase and a second manufacturing phase. A test MLC capacitor with buried overlapping electrodes is made and the capacitance of that test capacitor is measured. In the subsequent manufacturing phase the same process is used to make the same capacitor except adding to it at least one pair of coplanar electrodes whereby the small capacitance between each pair of coplanar electrodes is parallel connected with the base capacitor to bring the total capacitance up close to a target value. This method is particularly valuable for making close tolerance capacitors having only a few conventional overlapping electrodes, because each pair of coplanar capacitance-adjusting electrodes has a relatively small, stable, predictable incremental capacitance that is insensitive to changes in registration between successive electrodes.

A multilayer ceramic capacitor comprising: (a) a ceramic body having a top face and at least two spaced-apart side faces; (b) a plurality of mutually parallel spaced-apart film electrodes buried in said ceramic body, each of a first group of said electrodes extending to one of said two side faces and being disposed in overlapping capacitive relationship with at least one other of said electrodes, each of a second group of said electrodes extending to the other side face of said body and being disposed in overlapping capacitive relationship with at least one of said first group electrodes or at least one of another group of said electrodes that also has an overlapping relationship with at least one of said first group electrodes; (c) at least one pair of spaced-apart coplanar film electrodes buried in said body, one and the other of said pair of coplanar electrodes extending respectively to said one and the other side faces; and (d) two conductive terminations bonded respectively to said one and the other of said side faces to contact all of said extending electrodes at said respective faces.
