The sCMOS sensor's low read noise and larger area provides a low-noise, large field-of-view (FOV) image that enables researchers to scan across a sample and capture high-quality images. [9] [5] Some disadvantages at this time, (2023), with sCMOS cameras versus related technologies are: sCMOS sensors tend be more expensive than traditional CMOS ...
An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. [1] [2] In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as ...
The diagram to the right depicts how the Foveon X3 sensor works. The image on the left shows the absorption of colors for each wavelength as it passes through the silicon wafer. The image on the right shows a layered sensor stack depicting the colors it detects at each absorption level for each output pixel. The sensor colors shown are only ...
A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
The first CMOS gate arrays were developed by Robert Lipp, [5] [6] in 1974 for International Microcircuits, Inc. (IMI). [ 3 ] Metal–oxide–semiconductor (MOS) standard-cell technology was introduced by Fairchild and Motorola , under the trade names Micromosaic and Polycell, in the 1970s.
Charge coupled device (CCD) cameras were first applied to transmission electron microscopy in the 1980s and later became widespread. [3] [4] For use in a TEM, CCDs are typically coupled with a scintillator such as single crystal Yttrium aluminium garnet (YAG) in which electrons from the electron beam are converted to photons, which are then transferred to the sensor of the CCD via a fiber ...

Simplified process of fabrication of a CMOS inverter: Image title: Simplified process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication, drawn by CMG Lee. Note: Gate, source and drain contacts are not normally in the same plane in real devices, and the diagram is not to scale.
