  • Patent number: 11508775
    Abstract: The inventive concepts provide a three-dimensional (3D) image sensor, based on structured light (SL), having a structure in which difficulty in a manufacturing process of a wiring layer is decreased and/or an area of a bottom pad of a capacitor is increased. The 3D image sensor includes: a pixel area including a photodiode in a semiconductor substrate and a gate group including a plurality of gates; a multiple wiring layer on an upper portion of the pixel area, the multiple wiring layer including at least two wiring layers; and a capacitor structure between a first wiring layer on a lowermost wiring layer of the multiple wiring layer and a second wiring layer on the first wiring layer, the capacitor structure including a bottom pad, a top pad, and a plurality of capacitors, wherein the bottom pad is connected to the first wiring layer.

  • Patent number: 9263521
    Abstract: Integrated circuit devices including Fin field effect transistors (finFETs) and methods of forming those devices are provided. The methods may include forming a fin on a substrate and forming a gate line on the fin. The method may also include forming a first recess in the fin having a first width and a first depth and forming a second recess in the first recess having a second width that is less than the first width and having a second depth that is greater than the first depth. The method may further include forming a source/drain region in the first and second recesses.
