Vacuum chambers

Controlled low-pressure environments engineered for semiconductor fabrication, thin-film deposition, and space simulation.

Vacuum chambers are the backbone of high-precision manufacturing and aerospace testing. These vessels utilize 304L or 316L stainless steel to maintain structural integrity under extreme pressure differentials, reaching Ultra-High Vacuum (UHV) levels down to 10^-12 Torr. From 12-inch spherical chambers for R&D to massive thermal vacuum systems (TVAC) used by NASA for satellite qualification, these environments eliminate atmospheric interference. They are essential for processes like Physical Vapor Deposition (PVD) and extreme ultraviolet lithography (EUV), where even a single oxygen molecule can compromise a multi-million dollar wafer.
