An N+ buried layer is placed in the P- substrate beneath each transistor.  P+ regions then are placed in the substrate underneath (or optionally in lieu of) the later formed recessed oxide and underneath the emitter region of each later formed lateral transistor.  An N type epitaxial layer is deposited over the structure and the previously formed N+ and P+ substrate regions are outdiffused into the epitaxial layer, the P+ regions outdiffusing to a greater extent.  Recessed oxide iso-lation walls are made and P+ areas are introduced into the epitaxial layer to form the base of each NPN transistor and to form a collector and an extended depth emitter for each PNP transistor, said emitter reaching from the surface of the epitaxial layer to the underlying N+ buried layer.  The transistors are completed in the usual manner.

Abstract: ABSTRACT OF THE DISCLOSURE          To provide a closed loop hydrostatic transmission of pump and motor with a true acceleration control for the motor drive shaft, as opposed to a velocity control which may be achieved by varying the relative volume displacement of the pump and motor, the maximum delivery pressure of the pump is set by an accelerator and the relative volume of the pump and the motor is varied automatically by control means to maintain the pump delivery pressure at the maximum determined by the setting of the accelerator.  Thus the closed loop system maintains a substantially constant maximum pressure throughout the flow range of the transmission for each accelerator setting, and since the output torque of the motor is proportional to this system pressure, a true acceleration control is achieved.
