Patent ID: 7199457

Claim:
A thin film circuit board device comprising: a base board having a flattened main surface as a build-up forming surface, said flattened main surface including a wiring pattern surface; and a circuit part formed on the base board comprising: a first circuit layer operable to receive high frequency signals, the first circuit layer comprising a first insulating layer formed on said flattened main surface, a first substrate titanium layer formed on the first insulating layer and electrically connected to said wiring pattern surface of said base board, a first wiring layer formed on the first substrate titanium layer, and at least one passive element consisting of a capacitor or a resistor formed on the first insulating layer; a second circuit layer adapted to operate at a high frequency and formed on the first circuit layer, the second circuit layer comprising a second insulating layer; a second substrate titanium layer formed on the second insulating layer and electrically connected to said first wiring layer of said first circuit layer; and a second wiring layer formed on the second substrate titanium layer; and a receiving electrode formed on said first insulating layer and electrically connecting said at least one passive element to said first wiring layer, the receiving electrode having a titanium layer and an electrode layer sequentially laminated on the first insulating layer.
