Patent ID: 7778009

Claim:
A thin-film capacitor comprising: a thin-film capacitor element having a bottom conductive film, a top conductive film and a dielectric film sandwiched therebetween; an inorganic protective film covering said thin-film capacitor element and having second openings formed therein, each of the second openings exposing at least a part of said bottom conductive film; an organic protective film covering said thin-film capacitor element from above said inorganic protective film and having a first opening formed therein, the first opening exposing said second openings and being larger than said second openings; and a bump connected with said bottom conductive film via the first and second openings, wherein a contact area between said inorganic protective film and said bottom conductive film is larger than an area of said second openings, wherein a diameter of each of said second openings is equal to or smaller than one eighth of a diameter of said first opening, wherein all of a side surface of said bump, except for a portion in said second openings, is in contact with said organic protective film, wherein there is a step between said dielectric film and said bottom conductive film, wherein said inorganic protective film has a following portion which follows said step, wherein a normal direction of a surface of said following portion changes according to said step, wherein said inorganic protective film further has a flat portion closer to said bottom conductive film than said following portion, and wherein said second opening is formed in said flat portion.
