A semiconductor device including a MISFET formed in a well at a main surface of a substrate, a second MISFET formed at a main surface of the substrate, and a passive element formed over the main surface of the substrate and having two terminals. A conductive film is formed at a rear face of the semiconductor substrate. The conductive film is connected with a fixed potential and also electrically connected with the conductive film.

Semiconductor device and manufacturing the same

Multilayered semiconductor structure containing a MISFET, a resistor, a capacitor, and an inductor

A semiconductor device includes a transmission power amplifier having cascaded MOSFET amplification stages disposed over a main surface of a semiconductor substrate. A CMOSFET control circuit controls the amplification stages. A first capacitor is also provided having upper and lower metal film electrodes formed over the main surface of the semiconductor substrate. The amplification stages are electrically coupled to one another via an inter-stage matching circuit which includes the first capacitor.

Plural elements forming a high frequency device in one chip are provided by forming a resistor element and the lower electrode of a capacitor element from one identical polycrystal silicon film over a substrate; forming the gate electrode of a power MISFET, upper electrode of the capacitor element, gate electrode of an n-channel type MISFET and gate electrode of a p-channel type MISFET from an identical polycrystal silicon film different from the other polycrystal silicon film and a WSi film; forming a capacitor element having a wiring formed on a silicon oxide film deposited over the substrate as a lower electrode and a wiring formed on the silicon oxide film as the upper electrode in the region MIN; forming a spiral coil in a region IND using an aluminum alloy film identical with that deposited on a silicon oxide film; and forming a bonding pad in a region PAD.
