Molybdenum Sample Holders
Precision Substrate Platforms for DEAR-MPCVD Diamond Growth
The Molybdenum Sample Holders provide a stable, contamination-free platform for securing substrates within the Blue Wave Semiconductor DEAR-MPCVD system. Engineered from high-purity molybdenum, they deliver excellent thermal conductivity, strong plasma erosion resistance, and clean performance in high-temperature, high-vacuum environments.
Available in small, medium, and large sizes with customizable pocket dimensions and multiple height variants for precise substrate-to-plasma positioning.
