Patent ID: 7176550

Claim:
An electronic device ( 10 , 50 ) comprising a capacitor ( 12 ) and an inductive element ( 11 ), which capacitor ( 12 ) includes a first electrode ( 31 ) and a second electrode ( 32 ) and an intermediate dielectric ( 33 ), and which inductive element ( 11 ) comprises a first winding ( 21 ), which device ( 10 , 50 ) comprises a substrate ( 1 ), on a surface ( 2 ) of which there are present: a first metal film ( 3 ), in which the first winding ( 21 ) of said inductive element ( 11 ) and the first electrode ( 31 ) of the capacitor ( 12 ) are defined; a second metal film ( 6 ) comprising the second electrode ( 32 ) of the capacitor ( 12 ); a dielectric film ( 4 ) of a dielectric material, part of which is the dielectric ( 33 ), characterized in that: the first metal film ( 3 ) is present between the surface ( 2 ) of the substrate and the dielectric film ( 4 ) and has a thickness that is larger than a penetration depth at a minimal operation frequency; a patterned separation layer ( 5 ) of a dielectric material is present between the first and the second metal film ( 3 , 6 ), which separation layer ( 5 ) has a smaller capacitance density than the dielectric film ( 4 ), and a perpendicular projection of the separation layer ( 5 ) on the first metal film ( 3 ) falls partially within the first electrode ( 31 ) of the capacitor ( 12 ).
