Patent ID: 7727584

Claim:
A manufacturing method of a dielectric device comprising: a mixing step in which powders serving as a matrix and additive powders for sintering the matrix are mixed; a mixture heat-treating step in which the mixture of the matrix and the additive that has been subject to the mixing step is heat-treated; a deposition layer formation step in which material powders obtained through the mixture heat-treating step are injected to a substrate so as to form a deposition layer on the substrate, wherein the deposition layer formation step employs material powders containing a dielectric that contains a solid solution of lead zinc niobate and lead zirconate titanate (PZN-PZT), and a sintering aid containing ZnO—Bi 2 O 3 ; and a deposition layer heat-treating step in which the deposition layer formed on the substrate through the deposition layer formation step is heat-treated at a temperature not more than that at the mixture heat-treating step so as to form a dielectric layer on the substrate.
