Polished Stainless Steel Process Chamber, Custom Vacuum Chamber for Semiconductor
Polished stainless steel process chamber for vacuum, clean semiconductor and coating processes.
Our polished stainless steel process chamber is custom metal fabrication part built for high-purity, clean and vacuum working environments. We adopt electropolishing & mirror polishing treatment to achieve ultra-smooth inner surface, reducing particle retention and contamination risk.
It supports custom sizes, port layout, sight windows, flange connections and internal fixtures. Welds are fully ground and sealed, with helium leak test available for vacuum tightness.
Matched with KF/CF vacuum flanges, sealing gaskets, sensor ports and cooling jackets, this chamber fits semiconductor deposition, etching, thin film coating and R&D lab process systems. Material options include 304 / 316L stainless steel. All units go through strict dimensional, roughness and cleanliness inspection before delivery.
