Abstract: Some embodiments relate to an integrated chip including a substrate having a first side and a second side opposite the first side. The integrated chip further includes a first photodetector positioned in a first pixel region within the substrate. A floating diffusion region with a first doping concentration of a first polarity is positioned on the first side of the substrate in the first pixel region. A first body contact region with a second doping concentration of a second polarity different from the first polarity is positioned on the second side of the substrate in the first pixel region.

Abstract: A semiconductor device includes a fin structure. A source/drain region is formed on the fin structure. A first gate structure is disposed over the fin structure. A source/drain contact is disposed over the source/drain region. The source/drain contact has a protruding segment that protrudes at least partially over the first gate structure. The source/drain contact electrically couples together the source/drain region and the first gate structure.

Abstract: An electronic device includes a lens body, a rotatable portion, a base, and a main body. The lens body contains a lens module. The rotatable portion is secured to the lens body, and defines a number of grooves on the circumference surface thereof. The base defines a through hole with the rotatable portion received therein. An elastic sheet is disposed at a lateral side of the through hole and has a protrusion projecting into the through hole for engaging with the grooves of the rotatable portion. The main body is secured with the base.
