  • Patent number: 6888219
    Abstract: A semiconductor device has a silicon layer and a first dielectric layer. A transistor has a drain and a source that are at least partially in the silicon layer. The transistor further has a gate and a spacer defining the gate. The first dielectric layer forms the spacer. A capacitor has first and second electrodes, the first electrode is formed at least partially in the silicon layer, and the first dielectric layer provides a dielectric for the capacitor between the first and second electrodes. A resistor has a resistive region formed at least partially in the silicon layer and has first and second resistor contact areas defined by the first dielectric layer. A second dielectric layer electrically isolates the transistor, the capacitor, and the resistor from conductive lines.
