Abstract:
A 3D image sensor includes a first color filter configured to pass wavelengths of a first region of visible light and wavelengths of infrared light; a second color filter configured to pass wavelengths of a second region of visible light and the wavelengths of infrared light; and an infrared sensor configured to detect the wavelengths of infrared light passed through the first color filter.
Abstract:
An optical biosensor, and a method of manufacturing the same, includes a first layer, a second layer stacked on the first layer, a first grating coupler within the first layer and the second layer, and a second grating coupler within the first layer. The first grating coupler is configured to couple a light pattern provided to a front side of the optical biosensor. The second grating coupler is configured to output the light pattern coupled by the first grating coupler to a photoelectric conversion element on a rear side of the optical biosensor.
Abstract:
A recess gate transistor includes: a drain region and a source region in a semiconductor substrate and doped with first-type impurities; a recess region recessed in the semiconductor substrate between the drain region and the source region; a gate insulation layer on the recess region, a gate electrode on the gate insulation layer filling the recess region; and a charge pocket region below the recess region and doped with second-type impurities. A semiconductor chip includes a plurality of recess gate transistors, and an image sensor includes a semiconductor chip including a plurality of recess gate transistors.
Abstract:
A binary complementary metal-oxide-semiconductor (CMOS) image sensor includes a pixel array and a readout circuit. The pixel array includes at least one pixel having a plurality of sub-pixels. The readout circuit is configured to quantize a pixel signal output from the pixel using a reference signal. The pixel signal corresponds to sub-pixel signals output from sub-pixels, from among the plurality of sub-pixels, activated in response to incident light.
Abstract:
An operation method of an image sensor includes determining a distance between the image sensor and an object, and activating at least one of a color pixel, a depth pixel and a thermal pixel included in a pixel array of the image sensor based on a determined distance and a reference distance.
