Design and construction of standard and custom-built pressure vessels, vacuum chambers, reactors, heat exchangers, tanks, autoclaves, pipes for industrial and scientific research applications. The team from PVA Italy is active in all phases of organization and production planning. Each industrial plant or single equipment order is assigned to a specific work group that handles the entire production process, from design to final delivery.
Vacuum tight chambers with mirror-polished inner surfaces made from high-grade stainless steel are required for crystal growing processes at high temperature in semiconductor industry. Any metal contamination sources to the melt and growing crystal are reduced to an absolute minimum level by the optimized material selection, manufacturing procedures, and chamber cooling effectiveness. All chamber parts are double-walled for water-cooling. For CZ growth of a silicon crystal e.g., the required silicon is melted in the process chamber at 1450°C.
