Reticle & Mask Housings CNC Machining for Semiconductor Industry

Lead times for reticle mask housings depend on design complexity, material selection, and order quantity. Prototype quantities (1-5 pieces) with standard aluminum construction typically ship within 7-10 business days after design approval. Small production runs (10-25 pieces) require approximately 3-4 weeks including machining, anodizing, and inspection. Larger production orders (50+ pieces) are scheduled at 4-6 weeks to accommodate material procurement, manufacturing, and comprehensive quality documentation. For projects requiring specialized materials, coatings, or ultra-precision specifications, we provide detailed timelines during the quotation phase. Expedited services are available for urgent requirements with accelerated scheduling and dedicated manufacturing resources. 

Particle contamination control is paramount in our reticle mask housing manufacturing process. All final machining operations occur in our Class 1000 cleanroom manufacturing area with HEPA filtration and positive pressure controls. We use dedicated semiconductor-grade cutting fluids and implement comprehensive chip evacuation systems to prevent particle redeposition. Post-machining cleaning includes multi-stage ultrasonic cleaning with semiconductor-grade solvents, DI water rinsing, and nitrogen blow-drying. Parts undergo particle counting verification using light scattering inspection before packaging in double-bagged, ESD-safe cleanroom packaging. Our protocols ensure components arrive ready for immediate integration into Class 1 cleanroom lithography environments. 

Yes, we offer comprehensive anodizing services specifically calibrated for semiconductor reticle housing applications. Our Type II and Type III hard anodizing processes achieve precise coating thicknesses from 0.0002″ to 0.001″ with excellent uniformity. We provide clear, black, or custom color anodizing with controlled surface resistivity for ESD protection. All anodizing processes are performed to MIL-A-8625 specifications with post-treatment sealing for maximum corrosion resistance. Our quality control includes coating thickness verification, surface resistivity testing, and adhesion testing to ensure long-term durability in cleanroom environments. Material certifications and process documentation are provided with every order.
 

We consistently achieve tolerances of ±0.0003″ (±0.0076mm) for critical mounting surfaces and locating features on reticle mask housings. Flatness specifications are maintained to within 0.0005″ across large frame surfaces, with localized flatness often held to 0.0002″ for reticle contact areas. Perpendicularity and parallelism between critical surfaces routinely meet 0.0002″ tolerances. Our climate-controlled machining environment, precision fixturing, and advanced CMM inspection capabilities ensure these specifications are maintained consistently across production quantities, meeting the demanding requirements of modern lithography equipment manufacturers.
