    摘要: A low voltage circuit is used to control a high voltage transistor which operates a high voltage motor. A blocking diode and a bootstrap capacitor are used to shift the voltage of the circuit between two levels. The circuit is enabled by inducing a current flow through an input terminal. The current is amplified and applied to a high voltage transistor. The circuit is disabled by termination of the current flow through the input terminal which causes the circuit to rapidly disable current flow through the high voltage transistor. The circuit also disables current flow through the high voltage transistor during voltage transients to prevent erroneous operation during the transients.

    摘要: An improved method for making a self-aligned vertical field effect transistor is provided wherein a nitride sidewall spacer is formed around a polysilicon gate, and an oxide sidewall spacer, which may be heavily doped with an n-type dopant, is formed covering the silicon nitride sidewall spacer. The silicon nitride sidewall spacer allows the oxide sidewall spacer of a conventional self-aligned vertical field effect transistor process to be removed partially or completely before making ohmic contact to the source thus increasing the contact area between the source and the source electrode and eliminating reliability problems related to n-type doped oxide in contact with aluminum electrodes.

    摘要: An improved means and method is described for forming a Schottky diode integrated with transistors and other devices which is particularly useful where both control circuits and a large power device are on the same chip.Nested N-, P-, N- and P+ regions are formed on an N+ semiconductor substrate. A portion of the overlying dielectric is removed adjacent one of the P+ regions over the N- region and a Schottky contact formed to the N- region and an ohmic contact to the adjacent P+ region. N+ and P+ regions are desirably provided where the junctions between the N-/P- regions and the P-/N- regions intersect the surface to provide contact to the N- and P- regions respectively.A P region extends through the upper N- region and has U-shaped arms which partially overlie an annular shaped P+ region and is located between the active region of the PNP transistor and the collector contact to serve as a Kelvin probe. The arrangement is particularly valuable where a vertical PNP device without a buried collector region is required.

    摘要: A current ratioing device structure wherein a line of equally spaced emitter regions is parallel to another line of equally spaced base contact portions all within a base region. All of the emitter regions except the first and last emitter region in the line have contact portions so that the first and last emitter regions are "dummy" emitters.

    摘要: A sense amplifier which is fully integrated has an on-chip voltage regulator to provide essentially error free operation. The sense amplifier provides peak-to-peak signal detection for comparison to a threshold voltage by a comparator. The output of the comparator is coupled to an RS flip-flop. The output of the RS flip-flop is coupled to a D flip-flop. The use of an RS flip-flop as well as a D flip-flop eliminates clocking problems caused by skewing and keeps a stored detected signal from changing prematurely.

    摘要: A circuit for providing the gate of a bubble memory with a precision current pulse at a high voltage is manufactured using a low voltage process; i.e. BV.sub.ceo is approximately 18 volts. In order to accomplish this, first and second voltage level shifting stages are cascoded and the output transistors thereof are used as Zener level shifters each level shifting downward by a BV.sub.ceo when only a small voltage is dropped across the load. If the voltage drop across the load increases, the cascoded output transistors may enter their active region and are prevented from going into saturation by saturation clamps so as to not introduce unwanted delays in the rise or fall times of the current pulse.
