Abstract: PURPOSE:To enhance a semiconductor device in cut-off frequency by a method wherein a graft base diffusion layer of intermediate concentration and an emitter diffusion layer are formed in a self-aligned manner, a graft base diffusion layer of high impurity concentration and an emitter diffusion layer are formed in a self-alignment manner interposing an insulating between them, and a low resistive silicide film is formed on the high concentration graft base diffusion layer in a self-alignment manner. CONSTITUTION:A graft base diffusion layer 13a whose concentration is higher than that of a base diffusion layer is widely interposed between an emitter diffusion layer 16a and a high concentration graft base diffusion layer 13b at a narrow space. Therefore, a parasitic resistance between an emitter and a base is prevented from increasing. A low resistive silicide film is formed on the surface of the high concentration graft base diffusion layer 13b in a self-alignment manner, whereby the area of a base electrode hole 32a can be limited to the irreducible minimum. By this setup, a base region is not required to be unnecessarily increased in area, therefore a junction capacitance between an emitter and a base can be reduced to the irreducible minimum. By this setup, a parasitic resistance between an emitter and a base and a junction capacitance between a base and a collector can be lessened as compared with a conventional one.

Abstract: PURPOSE:To attain to simplify a circuit, by bringing a clamp switch to a continuity state simultaneously with or prior to the cutting-off of a reset switch. CONSTITUTION:When a reset switch 3 and a clamp switch 7 are brought to a continuity state at time t1, the signal charge of a contact 2 is reset and the sound terminal 6B of a connection condenser 6 is clamped. The switch 3 is cut off at time t2 and reset noise voltage is generated in the contact 2 but, because the switch 7 is in the continuity state, the reset noise voltage appearing at the second terminal 6B of the condenser 6 is rapidly clamped and output signal voltage V0 almost contains no reset noise voltage. The clamp 7 is cut off at time t3 and the clock voltage V1 of CCD changes and the clock voltage V1 applied to the final transmission electrode, to which clock voltage is applied, among transmission electrodes in CCD is returned to the original state at the time t1. By this method, the circuit can be simplified.
