In order to enable cutting of a soft ceramic green block by a dicing saw having excellent cutting accuracy, heat treatment is performed on the ceramic green block to dissociate a plasticizer, thereby improving hardness of the ceramic green block. Then the ceramic green block is cut by the dicing saw.

Method of cutting ceramic green block

In order to enable the cutting of a soft ceramic green block by a dicing saw with excellent cutting accuracy and at high speed, heat treatment is performed on the ceramic green block to dissociate a plasticizer, thereby improving the hardness of the ceramic green block. Thereafter the ceramic green block is cut by the dicing saw.

A ceramic multilayer substrate (,) having a built-in inductance includes a conductor (,) which is arranged in a substrate consisting of a sintered body (,), and ferromagnetic metal films (,A,,B) consisting of Ni which are arranged on both sides of the conductor (,).

Electronic component having built-in inductor

A method of manufacturing a monolithic ceramic electronic device includes the following steps: forming a first metal film on a PET film; forming a multilayered metal film by forming a second metal film on a part of the first metal film, the second metal film being thicker than the first metal film; forming a monolithic ceramic structure including the multilayered metal film; forming the first metal film, which is partially overlain by the second metal film in the monolithic ceramic structure, into an insulating structure in such a manner that metal components forming the first metal film are diffused into the ceramics; and firing the ceramics. Disclosed also is a monolithic ceramic electronic device manufactured by the method. As a result, a stepped portion between a portion in which the internal electrodes overlap one another and a portion in which the internal electrodes do not overlap can be prevented from being formed, and delamination can effectively be prevented, whereby a monolithic ceramic electronic device exhibiting stable characteristics and a method for manufacturing the monolithic ceramic electronic device can be obtained.

Method of manufacturing a monolithic ceramic electronic device

A method of manufacturing a resistor integrated in a sintered body, by patterning a plurality of metal thin films which are formed by a thin film forming method, thereafter transferring the patterned metal thin films onto a ceramic green sheet (11), stacking another ceramic green sheet and/or a ceramic green sheet stacked with another metal thin film thereon for obtaining a laminate, and firing the resulting laminate, thereby forming a resistor integrated in a sintered body which is structured by by alloying the plurality of metal thin films in a ceramic sintered body.

Method of manufacturing resistor integrated in sintered body and method

A method of fabricating an electronic component of multilayered type comprising the steps of sequentially forming and laminating a plurality of metal films respectively having different metal compositions for constituting the alloy composition of an inner electrode by the thin film forming process to obtain a laminated metal film, laminating a plurality of ceramic green sheets through laminated metal films such that the laminated metal film is arranged between the ceramic green sheets, sintering a laminated body thus obtained and alloying the laminated metal films to form a plurality of inner electrodes each composed of an alloy.
