MJ Enterprise supports key semiconductor manufacturing processes by supplying machined components built for high-vacuum, high-purity, and thermally controlled environments. We manufacture to exact customer drawings and quality specifications.

• Vacuum Chambers and Sealing Flanges
  We manufacture vacuum enclosures, baseplates, flanges, and sealing rings used in semiconductor fabrication tools like CVD, PVD, and ALD systems. Made from high-purity stainless steel (e.g., 316L, 304L) or aluminium alloys, these components offer vacuum integrity, low outgassing, and corrosion resistance under cleanroom conditions.
• Wafer Handling Components
  MJ produces parts such as wafer transfer arms, end-effectors, and robotic support brackets. These components are machined to ultra-tight tolerances with fine surface finishes (Ra < 0.2 μm) to prevent particle generation, ensuring contamination-free wafer movement during lithography, etching, or deposition processes.
• Gas Delivery and Flow System Components
  We manufacture manifolds, precision gas fittings, valves, and blocks used in semiconductor gas distribution setups. These parts are machined from stainless steel alloys maintain purity, holding precise dimensions to serve the specific applications.
• Thermal Management Plates and Fixtures
  For temperature-sensitive stages, MJ Enterprise supplies machined cooling plates, thermal clamps, and heatsink components designed to help regulate process temperatures. Our thermal management parts support consistent heat transfer and maintain stability during critical manufacturing processes.
