Range sensor and range image sensor
First Claim
1. A range sensor comprising:
- a charge generating region at which charges are generated in response to incident light;
first and second charge collecting regions arranged spatially apart from each other to collect the charges from the charge generating region; and
first and second transfer electrodes installed at the respective peripheries of the first and second charge collecting regions, wherein the first and second transfer electrodes receive charge transfer signals different in phase, and the first and second transfer electrodes completely surrounding the first and second charge collecting regions respectively.

Abstract
The range image sensor is a range image sensor which is provided on a semiconductor substrate with an imaging region composed of a plurality of two-dimensionally arranged units (pixel P), thereby obtaining a range image on the basis of charge quantities QL, QR output from the units. One of the units is provided with a charge generating region (region outside a transfer electrode 5) where charges are generated in response to incident light, at least two semiconductor regions 3 which are arranged spatially apart to collect charges from the charge generating region, and a transfer electrode 5 which is installed at each periphery of the semiconductor region 3, given a charge transfer signal different in phase, and surrounding the semiconductor region 3.
