FAQs: Vacuum Chamber Housings for Semiconductor Applications
Multi-axis CNC milling performs creation of chamber profiles along with mounting flanges, view ports, and service access doors as an integrated element of the chamber. Precision boring machines size and open large diameter ports and maintain concentricity within 0.005 inches for standardized vacuum flanges which conform to ISO, KF, and ConFlat standards. Face milling machines obtain the flatness and surface finish required on the O-ring sealing surfaces within 0.005 inches flatness and Ra surface finish of below 1.6 microns. Coordinate drilling achieves the accuracy required for the position of patterns for bolt holes within ±0.005 inches for mounting the flanges. Mounting threads are created by thread milling and electropolishing translates to stainless steel achieves Ra of below 0.4 microns by removing 10 to 50 microns of surface to reduce outgassing and particle adhesion. Distortion is reduced by stress-relief annealing.
The Aluminum 6061-T6, 5083, and 5086 characteristics include lightweight construction which reduces equipment floor loading and footprint, assisting in rapid temperature control which makes excellent thermal conductivity of 167 watts per meter-Kelvin and thermal conductivity, decreasing costs for larger processing chambers, easy machining for complex port integration and mounting features for vacuum chambers in construction, very low outgassing rates under 10⁻⁸ Torr-liters per second per square centimeter after required processing, and cost for large process chambers. Stainless Steel 304L and 316L provide maximum strength for balanced pressure atmospheric differential forces, and outstanding resistance to plasma fluorine and chlorine of the vacuum chamber materials, ultra-low outgassing under 10⁻⁹ Torr-liters per second electropolished vacuum chambers. which can be baked to 450~C for ultra-high vacuum processes. anodized aluminum exhibits excellent corrosion, abrasion resistance, and creation of hard surfaces at O-ring interfaces, electrical insulation for RF powered chambers, and vacuum chamber materials which in combination with polytetrafluoroethylene gaskets.
Vacuum chamber housings are fully integrated semiconductor fabrication equipment housings that provide a controlled vacuum environment for wafer processing. Process chamber housings can include various empty or integrated vacuum plasma etch, deposition, or ion implantation modules that operate at vacuum levels of 10⁻³ to 10⁻⁹ Torr. Various cryo-pump housings can be configured to provide ultra-high vacuum conditions of below 10⁻⁸ Torr. Other modules may include plasma confinement chambers for reactive ion etch and physical vapor deposition, as well as analytical chambers for measuring equipment. Special modules for 200mm, 300mm, and 450mm wafer processing include degas chambers, rapid thermal processing enclosures, pre-clean, and cryo-pump chambers.
