OVERVIEW
Zadient source material for PVT crystal growth is a granular product in the 1-12.5 mm particle size range produced by the Siemens CVD process, delivering the highest purity levels available in the market. Customized particle size ranges are available. Key features and benefits of this source material include:
-
Higher purity for lower defect density, higher yields
-
Higher bulk density for higher crucible loads, longer boules, more even thermal field
-
Larger particle size for better flow properties, easier handling, less dusting
-
More cubic particle shape for more stable sublimation rate
-
Higher production capacity for shorter lead times
