Sheet Resistance in CMOS VLSI means:

  1. The active devices of MOS technology having been dealt with in some measure, it is now appropriate to consider their interconnection as circuits.
  2. The ‘wiring-up’ of circuits takes place through the various conductive layers which are produced by the MOS processing
  3. It is therefore necessary to be aware of the resistive and capacitive characteristics of each layer.
  4. Concepts such as sheet resistance Rs and a standard unit of capacitance, help greatly in evaluating the effects of wiring and input and output capacitances.
