Abstract of the Disclosure

A junction transistor with an integrated circuit type base resistor functioning also as a diode or as a distributed auxiliary transistor between the base current input terminal and the collector so that excess current bypasses the base and the transistor is driven to about saturation to eliminate the storage time problem.

  • Figure 1 illustrates a schematic cross-section through a transistor in accordance with the invention whereby it is assumed that it is a portion of an integrated circuit chip, the vertical dimensions having been distorted relative to the horizontal dimensions for convenience of representation.
  • Figure 2 illustrates a top view of the transistor shown in principle in Figure 1.
  • Figure 3 illustrates schematically a section view of a portion of the transistor shown in Figures 1 and 2, being somewhat modified to explain some basic aspects of the operation and functioning of the transistor in accordance with the invention.
