Abstract: The present invention relates to a thin-film common mode filter comprising: a base substrate which is composed of insulating materials; a first insulating layer formed on the base substrate; an inner electrode formed on top of the first insulating layer and forms simultaneous coil patterns that overlap along the winding direction of two coil electrodes thereon; a second insulating layer formed on the inner electrode and is formed at a height higher than the interval between the coils; an external electrode terminal which is composed of a vertical section connected at the side surface of the inner electrode and a horizontal section horizontally extended from the top end of the vertical section and forms a parallel side separated from the inner electrode; and a ferrite resin layer which receives the first and second insulating layers, and a part of the side wall of the horizontal section of the external electrode terminal. The internal electrodes of the common mode filter are manufactured in a coil electrode type, and the coil electrodes form simultaneous coil patterns that overlap along the winding direction of two coils on a layer. Also, because the height of the second insulating layer formed on top of the inner electrode is higher than the interval between the coils, it can prevent parasitic capacitance generated sites fundamentally so that it may maintain the filtering function as a common mode filter and also has an effect to increase the self-resonant frequency (SRF).

The transparent electrode according to the present invention includes a graphene oxide layer at the upper and lower parts of a conductor and/or a semiconductor for having an insulating property between separated conductor and/or semiconductor and conductor and/or conductor, however the resistance measured at the surface of the graphene oxide layer maintains almost all of the resistance of the conductor and/or semiconductor at a transparent electrode including the grapheme oxide layer. Moreover, graphene oxide layer protects the transparent electrode by performing the role of a barrier layer for improving a long term reliability and transmittance by preventing the property of a transparent electrode from being lowered.
