Title: Solid-state image pickup element
Inventor: KUMAGAI KAZUYA
IPC: H04N5/3728
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state image pickup element which can perform the read of signal charge from a PD part to a vertical CCD part, suppressing the leaving behind the take of charge of a photoelectric converter to be small, by making the photoelectric converter in such structure that the potential distribution is inclined so that the accumulated charge may be easy to flow to the side of a charge transfer part. SOLUTION: At a solid-state image pickup element 101, a p<++> -type impurity layer 12 shallower in depth than a p<+> -type region 11 is made at the surface section on opposite side from the read gate part 101c of the p<+> -type region 1L constituting a PD part 101 a. Hereby, at the surface part of the PD part 101a, the potential level to electrons becomes higher on the side of a channel stopper layer 7 where the P<++> -type impurity layer 12 exists, and becomes lower on the side of the read gate part 101c where the p<++> -type impurity layer 12 does not exist, and the potential level becomes lower in stages toward the shifting direction of charge at read of charge. Therefore, it becomes easy for charge to shift from the PC part 101a to the vertical CCD part 101b, and the phenomena of a remaining image appearing on the screen by the charge left behind take can be suppressed.

IPC: G06F1/03
Filed: 1990-07-30
Abstract: PURPOSE:To freely select not only the frequency of continuation of points but also the number of points with respect to each part of a complicated waveform by performing required address designation by an arbitrary waveform generator based on a packet data word including a clock control word. CONSTITUTION:The packet data word including the clock control word from a control communication interface 12 is supplied to an arbitrary waveform generator logic circuit 16, and the circuit 16 not only determines the frequency of continuation of points of a digital waveform segment corresponding to the word but also generates a clock corresponding to the clock control word. The waveform segment is stored in a waveform memory and a multiplexer with this clock as the address, and intervals of points of the stored waveform are selected as desired by the address based on the desired clock. Consequently, not only the frequency of continuation of points but also the number of points is freely selected to adjust intervals of the waveform segment.
