Advanced Ceramic Solutions Inc. has launched a new line of boron nitride ceramic discs designed specifically for high-temperature annealing of silicon carbide wafers. These substrates offer exceptional thermal stability and electrical insulation, making them ideal for demanding semiconductor manufacturing processes.

Silicon carbide wafers require precise heat treatment to achieve desired electronic properties. Standard materials often warp or degrade under extreme temperatures. The new boron nitride discs remain stable even above 1800°C. They also resist chemical reactions with the wafer surface, which helps maintain purity during processing.
The discs are made using a proprietary hot-pressing method that ensures uniform density and smooth surface finish. This reduces particle contamination and improves yield in wafer production. Their low thermal expansion coefficient minimizes stress on the wafers during rapid heating and cooling cycles.
Manufacturers have already tested the discs in pilot runs. Early feedback shows consistent performance across multiple annealing cycles. Users report fewer defects and better repeatability compared to traditional graphite or alumina fixtures.
Boron nitride is known for its lubricity and non-wetting behavior. This means silicon carbide wafers do not stick to the disc surface during high-temperature exposure. Removal after annealing is easier and less likely to cause damage.
Advanced Ceramic Solutions Inc. produces these discs in various diameters and thicknesses to match standard wafer sizes. Custom dimensions are also available upon request. The company ships globally and supports integration into existing furnace setups.
