Manufacturing Process

The manufacturing process of boron nitride wafers involves advanced techniques to achieve the desired properties and quality. Some common methods include:

1. Chemical Vapor Deposition (CVD)

CVD is a widely used technique for growing high-quality boron nitride films on substrates. In this process, precursors containing boron and nitrogen are introduced into a chamber, where they react to form a thin film of boron nitride on the substrate surface. CVD offers precise control over film thickness and uniformity, making it suitable for large-scale production.

2. Hot Pressing

Hot-pressing involves compressing boron nitride powder at high temperatures and pressures to form dense wafers. This method is particularly effective for producing bulk boron nitride materials with high purity and mechanical strength.
