Limitations to the scaling of Schottky barrier diodes

Schottky barrier diodes are being used with bipolar digital circuits in many new circuit configurations. The need for low barrier Schottky diodes is very apparent now. The extreme sensitivity of the Schottky barrier diodes to temperature makes the range of spread of their parameters (area and barrier height) very limited. Also, it is shown that the Schottky barrier height has to be scaled as the logarithmic function of the area of the diodes.
