摘要： A solid-state image pickup device for preventing crosstalk between adjacent pixels by providing an overflow barrier at the deep potion of a substrate. A partial P type region is provided at the predetermined position of a lower layer region of the vertical transfer register and a channel stop region. This P type region adjusts potential in the lower layer region of the vertical transfer register and the channel stop region. Accordingly, since the potential in the lower layer region of the vertical transfer register and the channel stop region at both sides of the lower layer region is low, electric charges photoelectrically-converted by the sensor region are blocked by this potential barrier and cannot be diffused easily.

摘要： Crosstalk between the adjacent pixels can be prevented by a structure in which an overflow barrier is provided at the deep potion of a substrate. A partial P type region 150 is provided at the predetermined position of a lower layer region of the vertical transfer register 124 and a channel stop region 126. This P type region 150 is used to adjust potential in the lower layer region of the vertical transfer register 124 and the channel stop region 126 so that the potential may become smaller than that of the lower layer region of the photosensor 122 in a range from the minimum potential position of the vertical transfer register 124 to the overflow barrier 128. Accordingly, since the potential in the lower layer region of the vertical transfer register 124 and the channel stop region 126 at both sides of the lower layer region is low, electric charges photoelectrically-converted by the sensor region are blocked by this potential barrier and cannot be diffused easily. Thus, crosstalk between the adjacent pixels can be prevented.

摘要： A solid-state imaging device includes a layer including an on-chip lens above a sensor section, and the layer including the on-chip lens is composed of an inorganic film which transmits ultraviolet light. The layer including the on-chip lens may further include a planarizing film located below the on-chip lens. A method of fabricating a solid-state imaging device includes the steps of forming a planarizing film composed of a first inorganic film, forming a second inorganic film on the planarizing film, forming a lens-shaped resist layer on the second inorganic film, and etching back the resist layer to form an on-chip lens composed of the second inorganic film. The first inorganic film constituting the planarizing film and the second inorganic film constituting the on-chip lens preferably transmit ultraviolet light.

摘要： A solid-state imaging device having a gate structure including an oxide film and a nitride film includes upper layer films (for example, a planarization film, an insulating film, and a protective film) allowing ultraviolet rays having a wavelength of 400 nm or less to pass therethrough; and a metal made shield film or an organic film capable of absorbing the ultraviolet rays formed in such a manner as to cover a region of the gate structure (for example, an output gate and a reset gate), excluding a light receiving portion and a transfer portion, of the solid-state imaging device. With this configuration, it is possible to prevent the shift of a threshold voltage Vth, and hence to enhance the reliability of the transfer or reset of electric charges.
