A method for manufacturing the dielectric ceramic layer and the internal polar
layer of the multiple layer ceramic capacitor by the vacuum sputtering process
in which the dielectric ceramic layer and the internal polar layer of the MLCC
has a finest thinness of 15 m for the dielectric ceramic layer and
0.1 0.5 m for the internal polar layer. Comparing the size and the
voltage resistance with the MLCC formed by the traditional dot blade method—both
the dry process and the wet process, the MLCC produced by the vacuum sputtering
process is finer and thinner; comparing the layer number and the capacitance with
the MLCC formed by the tradition dot blade method, the MLCC produced by the vacuum
sputtering process has greater layer number and larger capacitance in the same
size. When comparing with the layer number and the capacitance, the MLCC formed
by the vacuum sputtering process has lesser layers.
