  • RC-networks in semiconductor devices and method therefor
    Patent number: 6208009
    Abstract: An improved RC network integrated circuit semiconductor device is disclosed which incorporates an improved method for fabrication. The new device and method includes the use of a tantalum nitride layer as the resistive material for the resistor and a protective metal layer formed between the resistive layer and a metal interconnect layer. The capacitor uses a metal electrode as one plate of the capacitor and a heavily doped semiconductor region as the other plate of the capacitor and separated from the one plate of the capacitor by a silicon nitride insulation layer.
