発明の名称 (英語) SEMICONDUCTOR ELEMENT AND SOLID-STATE IMAGE PICKUP DEVICE
発明の概要(英語) Provided is a semiconductor element that includes: a charge transfer path through which a signal charge defined in semiconductor areas (34, 35) is transferred; a pair of first electric field control electrodes (42a, 42b) that are arranged on the semiconductor areas so that the charge transfer path is interposed therebetween; and a pair of second electric field control electrodes (43a, 43b) that are arranged next to the first electric field control electrodes (42a, 42b), respectively, while being separated from the same, respectively. Different electric field control voltages are applied to the first electric field control electrodes (42a, 42b) and the second electric field control electrodes (43a, 43b), respectively, so as to change a depletion potential of the charge transfer path, whereby the movement of the signal charge being transferred in the semiconductor areas is controlled. As this makes it possible to make the electric field uniform over the long distance in the charge transfer direction, a semiconductor element and a solid-state image pickup device that can avoid a problem originating from an interface defect or the like can be provided.
