Classification: H01L

Abstract:
A signal detecting apparatus in a charge coupled device (CCD) having a photodiode for converting an image signal into an electrical signal charge, a vertical CCD (VCCD) for transferring the signal charge in a vertical direction, a horizontal CCD (HCCD) for transferring the vertically transferred signal charge in a horizontal direction, and a sense amplifier for sensing the signal charge transferred from the HCCD, the signal detecting apparatus comprising:a floating diffusion region for collecting the signal charges transferred from the HCCD and detecting a voltage formed by the signal charges;a reset gate on one side of the floating diffusion region;a reset drain on one side of the reset gate opposite to the floating diffusion region;an output gate formed on the other side of the floating diffusion region; and,a transistor having a gate connected to and formed at an angle with respect to a primary axis of the floating diffusion region, the angle being greater than 0.degree. and less than 90.degree..
