Abstract
Abstract A metal film (12) for providing internal electrodes (22) is formed on a back film (11) made of a material such as polyethylene terephthalate by a thin film forming method such as vapor deposition or sputtering. A ceramic green sheet (14) is prepared. Then the metal film (12) is transferred onto the green sheet from the back film (11). In order to form the metal film (12) to be transferred into prescribed patterns, the metal film (12) may be partially removed from the back film (11) to leave only specific parts which are correlative with the prescribed patterns. Alternatively, only specific parts, which are correlative with the prescribed patterns, of the back film (11) may be pressed against the ceramic green sheet (14). A plurality of such ceramic green sheets (14), onto which the parts of the metal films (120 are transferred, have been stacked with each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A method of manufacturing a laminated ceramic electronic component having internal electrodes formed in a pattern, comprising the steps of: forming a metal film on a back film by a thin film forming method; removing part of said metal film from said back film to leave only specific parts of said metal film on said back film, said specific parts being arranged on said back film in an arrangement which corresponds to said internal electrode pattern to be formed on said ceramic green sheet; and providing a ceramic green sheet for receiving said metal film; transferring said metal film parts onto said ceramic green sheet from said back film to form said internal electrodes by contacting the green sheet with the back film/metal film component such that the metal film is transferred to the green sheet; stacking a plurality of said ceramic green sheets on which respective said internal electrodes have been formed to thereby form said laminated ceramic electronic component having internal electrodes formed in a pattern.
Claim 2
Independent Claim
168 words
A method of manufacturing a laminated ceramic electronic component having internal electrodes formed in a pattern, comprising the steps of: forming a metal film on a back film by a thin film forming method; removing part of said metal film from said back film to leave only specific parts of said metal film on said back film, said specific parts being arranged on said back film in an arrangement which corresponds to said internal electrode pattern to be formed on said ceramic green sheet; and providing a ceramic green sheet for receiving said metal film; transferring said metal film parts onto said ceramic green sheet from said back film to form said internal electrodes by contacting the green sheet with the back film/metal film component such that the metal film is transferred to the green sheet; stacking a plurality of said ceramic green sheets on which respective said internal electrodes have been formed to thereby form said laminated ceramic electronic component having internal electrodes formed in a pattern.
Claim 3
Dependent Claim
31 words
A method of manufacturing a laminated ceramic electronic component in accordance with claim 1, wherein said thin film forming method is selected from the group consisting of vapor deposition and sputtering.
Claim 4
Dependent Claim
28 words
A method of manufacturing a laminated ceramic electronic component in accordance with claim 1, wherein the thickness of said metal film is approximately from 0.2 to 2.0 μm.
Claim 5
Dependent Claim
83 words
A method of manufacturing a laminated ceramic electronic component in accordance with claim 1, wherein said step of removing part of said metal film from said back film includes the steps of: forming a resist film on parts of said metal film corresponding to said specific parts of said metal film to be left on said back film; and applying a removing agent to said metal film so as to remove all parts thereof that do not have said resist film formed thereon.
