Abstract:
A method for manufacturing a laminated composite electronic device comprising the steps of:providing a first ceramic layer, a second ceramic layer and intermediate ceramic layers positioned between said first and second ceramic layers to form a laminated body, said first ceramic layer having a coefficient of linear expansion greater than that of the second ceramic layer and the intermediate ceramic layers having respectively decreasing coefficients of linear expansion from the intermediate layer closest to the first ceramic layer to the intermediate layer closest to the second ceramic layer, the intermediate ceramic layer closest to the first ceramic layer having a coefficient of linear expansion less than that of the first ceramic layer and the intermediate layer closest to the second ceramic layer having a coefficient of linear expansion greater than that of the second ceramic layer, said intermediate ceramic layers having varying NiO and ZnO contents for adjusting the thermal expansion rates thereof; andbaking the laminated body to form the laminated composite electronic device.
