摘要:
A method that employs a novel combination of conventional fabrication techniques provides a ceramic short-resistant capacitor (30) that is bendable and/or shapeable to provide a multiple layer capacitor that is extremely compact and amenable to desirable geometries. The method allows thinner and more flexible ceramic capacitors to be made. The method includes forming a first thin metal layer (12) on a substrate (10); depositing a thin, ceramic dielectric layer (14) over the metal layer (12); depositing a second thin metal layer (18) over the dielectric layer to form a capacitor exhibiting a benign failure mode; and separating the capacitor (30) from the substrate (10).

A method of manufacturing a monolithic ceramic electronic device includes the following steps: forming a first metal film (12) on a PET film (11); forming a multilayered metal film (17) by forming a second metal film (14) on a part of the first metal film, the second metal film being thicker than the first metal film; forming a monolithic ceramic structure (18) including the multilayered metal film (17); forming a portion of the first metal film (12), which is overlain by the second metal film (14) in the monolithic ceramic structure, into an insulating structure in such a manner that metal components forming the part are diffused into ceramics (16); 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, generation of 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.
摘要:
A method for making a substrate for use in a multilayered integrated circuit or multichip module which includes coating a conductive material (14) on a surface of a support sheet (10) to form a conductive circuit (12) and then drying the sheet. Next, a coating of a layer of dielectric layer (18) is placed on the support surface in the areas where the conductive material is not cast. After which the coated sheet is densified to form a densified conductive circuit embedded dielectric layer. A second coating of a dielectric (28) is placed over the first densified conductive circuit embedded dielectric layer such that the second layer is characterized by vias (30) therein which are in register with at least a portion of the conductive circuit (12). The vias in the second dielectric layer are filled to form electrically conductive vias and then densified to form the substrate (44).
摘要:
An electrode-embedded green ceramic sheet (25) formed on a suppport member is attached with pressure onto another green ceramic sheet or an electrode (23). Then, the support member only is peeled off, and the electrode-embedded green ceramic sheet (25) is transferred onto the second green ceramic sheet or electrode (23) so as to be laminated thereon. According to this production method, even a green ceramic sheet having a thickness of as small as 20 microns or less can be laminated maintaining mechanical strength. The electrodes embedded in the green ceramic sheet do not cause the surfaces to become rugged even when many sheets are laminated one upon another.
摘要:
A method and apparatus for manufacturing electrodes for capacitors having a plurality of thin metal coatings on a ceramic dielectric substrate, with the coated substrates assembled in a mononlithic structure. A layer of green ceramic material (10) is formed on a support tape. This green ceramic tape (10) is moved in registration with a stencil web (20) overlying the tape. The stencil web has openings corresponding to the configuration of the conductive coating to be formed on the tape. The sandwich of tape and web is moved through a sputtering chamber (28) in which a selected metal or alloy is sputtered from a target (30) so as to fall on the stencil web (20), coating the ceramic tape wherever openings are present. The sputtering chamber is arranged so that initially the ceramic tape receives a light, low energy metal coating before being exposed to maximum sputtering. This allows a reflective coating to be formed to reflect thermal energy before the intensity of the thermal radiation reaches a level that would damage an uncoated ceramic. The coated ceramic substrate tape may then be divided and assembled into multi-layer monolithic capacitors. In a related embodiment, the metallic electrodes may be sputtered onto a plastic carrier film to form a transferable layer or decalcomania, with the electrodes later transferred to the surface of the ceramic substrate.

The invention concerns the field of microelectronics and relates to a compact capacitor, which can be used, for example, in high-frequency oscillating circuits and in high-frequency filters. The problem addressed by the invention is that of specifying a compact micro- or nanocapacitor that has reliable and simple contacting of the functional layers. This problem is solved by means of a method for producing a compact micro- or nanocapacitor, in which method a layer stack consisting of at least two functional layers and two layers of a two-dimensional material and consisting of at least two layers of an electrically insulating material is arranged on a substrate, and the at least two functional layers and the layers of a two-dimensional material are arranged protruding beyond the width of the layer stack transversely to the rolling direction on one side each alternately, and then the layer stack is rolled up and the protruding are integrally bonded to each other.
