Leaky Schottky barrier diodes affect the noise tolerance and stability in circuits using Schottky barrier diodes at low currents, such as in random-access memory cells. The cause of these leakages is illustrated in Fig. 1 as localized N+ regions in the Schottky barrier diode areas arising from emitter diffusions through randomly-occurring pinholes in the insulator 3 overlying these areas. This results in undesired ohmic contacts rather than Schottky barrier contacts.
