A wafer is a thin semiconductor slice, such as crystalline silicon (c-Si), used in electronics to create integrated circuits and, in photovoltaics, to create solar cells. Wafers are sometimes referred to as slices or substrates.
Microelectronic devices are constructed inside and on top of the wafer, which acts as their substrate. Black silicon, a surface modification of silicon with very low reflectivity and consequently strong absorption of visible (and infrared) light, is a semiconductor material.
This substance is intriguing for sensor applications due to its peculiar optical features and silicon’s semiconductor capabilities.
Due to their affordability and conductivity, silicon wafers serve as a substrate for microelectronic devices and are particularly helpful when constructing electronic circuits.
The Global Electronics Black Wafer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
6-inch SiC Single Crystal Wafers are now being produced in bulk by SDK. Using materials for SiC epitaxial wafers*1 that will be processed and integrated into SiC-based power semiconductors, Showa Denko K.K. (SDK) (TOKYO: 4004) has begun mass producing silicon carbide single crystal wafers (SiC wafers) with a diameter of 6 inches (150 mm) (SiC power semiconductors).
SiC power semiconductors perform far better in terms of heat resistance and high withstanding voltage than conventional silicon-based power semiconductors, which are currently the most common type of power semiconductors.
SiC power semiconductor helps reduce the size and increase the energy efficiency of power modules. As a result, there is a fast growing need for SiC power semiconductors in many industries, particularly those that employ them in xEVs, railcars, and industrial machinery.
Power-device manufacturers have relied on SDK as an independent provider of SiC epitaxial wafers for Best in Class SiC epitaxial wafers, and SDK currently holds the market’s largest share globally.
Hence, power-device manufacturers both inside and outside of Japan are quite pleased with SDK’s SiC epitaxial wafers. To enhance the quality of their SiC wafers, SDK has considered producing them internally. SiC wafers are the primary component of SiC epitaxial wafers.
