Title:
CHARGE COUPLED DEVICE
Document Type and Number:
Japanese Patent JPS5655081
Kind Code:
A
Abstract:
PURPOSE:To improve the yield of a charge coupled device by forming an electrode for transferring a signal charge to a charge transfer device of the transfer electrode of the charge transfer device, making the feeding voltage and the transfer voltage different from each other, thereby eliminating the crossover of the electrode. CONSTITUTION:An electrode for feeding the signal charge obtained from the photoreceptor on a semiconductor substrate 1 to a charge transfer device of the transfer electrode 3 of the charge transfer device so that the voltage for feeding the signal charge and the voltage for feeding in the charge transfer device are differentiated. For instance, an N<+> type layer of diffused high density is formed on the P type substrate 1 to thereby form a photodiode 2, an N-channel element is formed, and a P type layer 7 is formed as a potential barrier in the transfer channel 6. Then, the clock pulse of the amplitude A is applied to the electrode 3, the light signal voltage read at previous operation is dispatched to an output device, a pulse having a width B is applied at the time of completing the operation, and a charge is fed from the photodiode 2 to the transfer channel.
