Claim 11:
12. An electronic component comprising:
a first insulating film comprising a silicon oxide formed on a substrate;
a first conductive layer directly formed on the first insulating film, the first conductive layer including a first conductive pattern having an upper surface and a side surface and a first inductor pattern having an upper surface and a side surface;
a second insulating film comprising a silicon nitride directly formed on the first insulating film and upper and side surfaces of each of the first conductive pattern and the first inductor pattern; and
a first insulating layer comprising an organic material, the first insulating layer having a first region that is in contact with the second insulating film and a second region surrounding the first region, the second region being in contact with the first insulating film,
wherein the first insulating layer has a cavity surrounded by the first inductor pattern such that a part of the first insulating film is exposed,
wherein the cavity includes a lower section exposing the part of the first insulating film and an upper section located above the lower section, and
wherein the lower section is greater in diameter than the upper section.
