Abstract: A floating diffusion (331) is created substantially at center of the light-receiving surface of an embedded photodiode (31), with a gate electrode of a transfer transistor (32) surrounding the floating diffusion. The concentration (or depth) of impurities in a p+-type semiconductor region, n-type semiconductor region or p-well region is changed in an inclined form so that a potential gradient being inclined downwards from the circumference to the center is created when an appropriate bias voltage is applied to the pn junction. The photocharges produced by incident light are rapidly moved along the potential gradient toward the center. Even in the case where the photocharge storage time is short, the photocharges can be efficiently collected since the maximum moving distance from the circumference of the photodiode (31) to the floating diffusion (331). Thus, the photocharges produced by the photodiode (31) are efficiently utilized, whereby the detection sensitivity is improved.

Abstract: Semiconductor devices and methods for making such devices that are especially suited for high-frequency applications are described. The semiconductor devices combine a SIT (or a junction field-effect transistor [JFET]) architecture with a PN super-junction structure. The SIT architecture can be made using a trench formation containing a gate that is sandwiched between thick dielectric layers. While the gate is vertically sandwiched between the two isolating regions in the trench, it is also connected to a region of one conductivity type of the super-junction structure, thereby allowing control of the current path of the semiconductor device. Such semiconductor devices have a lower specific resistance and capacitance relative to conventional planar gate and recessed gate SIT semiconductor devices. Other embodiments are described.
