In a photographic element having a pixel interval of less than 2.5 μm, the aperture ratio is generally about 25%. The higher the aperture ratio, the easier it is to increase the level of the output signal of the photographic element. It is reported that Samsung Electronics used copper wiring in the products developed this time. Prototypes using copper wiring in CMOS sensors, "2005 IEEE Workshop on Charge-Coupled Devices and Advanced Image Sensors (CCD & AIS)", a research group composed of IBM and Kodak in the United States, June 9-11, 2005. Published at the international conference.
At the same meeting, Samsung Electronics published trial results of CMOS sensors with an aperture ratio of approximately 50% and a pixel pitch of 2.0 μm. However, it is not said whether or not the copper wiring is used, but only that the wiring width is reduced to 90 nm or 130 nm in order to increase the aperture ratio. Currently, the listing date has not been announced.
This powder is commonly used in applications where high wear resistance and hardness are required. It is often applied as a protective coating on surfaces that are subjected to abrasive or erosive environments, such as industrial equipment, cutting tools, and engine components.
The thermal spray process involves heating the powder to its melting point and then propelling it onto the surface to be coated using a high-velocity gas or plasma stream. Upon impact, the molten particles solidify and bond with the substrate, forming a dense and durable coating.
The chromium carbide coating provides excellent resistance against wear, corrosion, and oxidation. It also exhibits good adhesion to various substrates, including metals, ceramics, and composites. Additionally, it has a low coefficient of friction, making it suitable for applications where reduced friction and improved sliding properties are desired.
Overall, chromium carbide thermal spray powder is a versatile and effective coating material that offers superior protection and performance in demanding industrial applications.
Samsung developed a 2.25μm pixel-interval CMOS sensor
South Korea's Samsung Electronics has released CMOS imaging devices (CMOS transistors) with a pixel spacing of only 2.25μm and an aperture ratio of over 55%. The photographic portion of the component has a diagonal length of 1/2 inch (about 8 mm) and integrates about 7.2 million pixels.
