Title: Semiconductor device
Inventor: YOSHIKAWA TOSHIBUMI
IPC: H01L29/74
Filed: 1981-09-30
Abstract: PURPOSE:To improve a critical OFF voltage increase rate (dv/dt)M of a lateral photo silicon controlled rectifier (SCR) by making large hFE of pnp element and photo sensitivity by thermal treatment, making small a gate resistance and by integrating elements in the same chip. CONSTITUTION:Response of pnp element of photo SCR delays when hFE is made large, and when a gate resistance is RG, a gate voltage VG CRGXdv/dt, and RG is made small, a critical off voltage increase rate becomes large. Meanwhile, a displacement current by dv/dt is a transient phenomenon and therefore (dv/dt)M can be improved remarkably by making large hFE and small RG by a mutual reinforcing effect by these two effects. When hFE is increased by making longer the life time of base layer, a photo sensitivity is generally enhanced, while the minimum trigger current reduces a little and the (dv/dt)M is improved. Such photo sensitivity is improved by about 30% through annealing under the N2 atmosphere at 900 deg.C. A value of dv/dt can be improved by about three times as compared with that when a resistance is externally provided by forming the RG with the P layer 9 in the N type substrate 1 and connecting the one end thereof to the gate 3 while the other end to the cathode 8 through the electrode 10.

A level of the line, the inverse of DL is input to a gate of a transistor T5 through an inverter 1A, and a current of the transistor T5 is consequently decreased. After a memory is selected, the current flowing in the transistor T5 is reduced by I to i0I, whereby the current is detected and a potential of the inverse of OUT is reduced. Bit lines can accordingly hold potentials independently of each other.

Filed: 1983-08-29
Abstract: PURPOSE:To prevent the abnormal increase of currents in the circuit on the opening of a semiconductor substrate by connecting a depletion type MISFET between the terminal of the substrate and a ground terminal on the substrate. CONSTITUTION:When a P type Si substrate 1 is isolated by thick oxide films 17-19, N<+> layers 2-8 are formed and FETs Q1, Q3-Q5 (a threshold VT1) are formed and wirings 20, 21 are formed on isolation films 17, 18, a FETQ2 (a threshold VT2) is parasitized. The circuit is connected according to a predetermined method, and a power supply terminal 25 is used as positive and a substrate terminal 27 as negative to the ground terminal 26 on normalcy. Currents do not flow through the Q2 because VT2 is under the state in which it is higher than VT1 at that time. Since the depletion type Q5 is formed between the ground terminal 26 and the substrate termimal 27 as a clamping element, drain currents flow even when substrate potential rises slightly, the potential rise of the substrate is prevented, difference between VT1 and VT2 is large even when the substrate terminal 27 is opened, the electric resistance of the parasitic Q2 is kept high, and abnormal currents do not flow in the IC.
