阅读说明:本技术 具有提高的电容量的薄膜电容器 (Thin film capacitor with improved capacitance ) 是由 K.迈尔 于 2020-04-09 设计创作,主要内容包括:本发明涉及一种由第一和第二薄膜构成的薄膜电容器,其中,两个薄膜分别具有相对介电常数ε-(r)并且分别在至少一个侧面上涂层或蒸镀有金属层。本发明还涉及一种用于制造这种薄膜电容器的方法。根据本发明,至少一个由具有相对于薄膜的介电常数ε-(r)更高的介电常数ε-(r)的电介质构成的层优选全面地布置在两个薄膜之间。由电介质构成的层在此要么印刷在一个或两个薄膜的金属层上,要么印刷在一个或两个薄膜的与金属化部对置的未涂层的侧面上。作为对此的备选,至少一个由电介质构成的层印刷在第一薄膜的金属层上,并且第二薄膜布置为,使得其金属层指向第一薄膜的金属层,从而第一薄膜的金属层和第二薄膜的金属层只通过薄的电介质层彼此分隔开。(The invention relates to a film capacitor consisting of a first and a second film, wherein the two films each have a relative dielectric constant epsilon r And is coated or evaporated with a metal layer on at least one side, respectively. The invention also relates to a method for producing such a film capacitor. According to the invention, at least one of the layers has a dielectric constant epsilon with respect to the film r Higher dielectric constant ε r Preferably over the entire surface of the layer of dielectricIs arranged between the two films. The layer of dielectric is printed either on the metal layer of one or both films or on the uncoated side of one or both films opposite the metallization. As an alternative to this, at least one layer made of a dielectric is printed on the metal layer of the first film, and the second film is arranged such that its metal layer points towards the metal layer of the first film, so that the metal layer of the first film and the metal layer of the second film are separated from one another only by the thin dielectric layer.)
