Title: Semiconductor integrated circuit device
Inventor: SUZUKI KOICHI
IPC: H01L27/04
Filed: 1989-02-09
Abstract: PURPOSE:To contrive to spread the range of a voltage which is applied to the rear of a chip by a method wherein high conductive layers, through which a power supply is supplied from the rear of a semiconductor substrate to be formed with an opposite conductivity type semiconductor layer to the side of the surface of the substrate, are set into a conductivity type identical with that of an element formation layer. CONSTITUTION:In case a first conductivity type and a second conductivity type are respectively assumed to be n-type and p-type, a positive bias voltage is not applied between a high- resistance p-type layer 32 and an n-type layer 33 for element formation use and between the layer 32 and n-type high conductive layers 35 for power supply use by applying the lowest voltage to a p-type isolation 34 formed in the layer 33. Accordingly, s voltage which is applied to an electrode layer 30 formed on the rear of an n-type substrate 31 is not limited to the lowest voltage and the voltage which is applied to the layer 30 can be supplied to the side of the surface of the substrate 31 through the layers 35. Then, in case the first and second conductivity types are respectively assumed to be a (p) type and an (n) type, a voltage which is applied to the layer 30 formed on the rear of the n-type substrate 31 is not limited to the highest voltage and can be supplied to the side of the surface of a p-type substrate 31. In such a way, the range of selection of a supply voltage which is supplied from the back surface of a chip can be spread.

Title: Power supply circuit of amplifying element
Inventor: SUEYOSHI SUSUMU
IPC: H03F1/02
Filed: 1982-03-05
Abstract: PURPOSE:To ensure a smooth ON/OFF action of a switching element, by generating a fixed stable hysteresis with addition of a resistance, etc. CONSTITUTION:A circuit power supply VCC has a rise when a power supply switch is applied at a time point T0. In this case, no input signal exists and therefore an output V0 is set at OV. The voltage V1 is set at first to 0 and then to V2=VCCR5/(R5+R6) since a capacitor C1 has no electric charge. As a result, a transistor TRQ3 is turned on, and the output of a comparator 3 generates the control voltage to turn on a switching element 4. Therefore the output voltage Vb of the capacitor C1 rises up on the basis of a charging curve 5. A TRQ2 is turned on in the case of Vb>ES2, and the output state of the comparator 3 is inverted. Thus the element 4 is turned off at a time point T1. A signal of a positive half cycle emerges at the output V0 at a time point T2 and then rises up, and at the same time the electric charge of the capacitor C1 is discharged. Then the voltage Vb begins to lower. When Vb<=V0+ES1 is satisfied at a time point T3, the output of the comparator 3 is inverted. Thus the element 4 is instantaneously turned on.
