Where to Order Custom Shadow Masks
Shadow masks are essential tools for PVD, CVD, sputtering, evaporation, sensor fabrication, thin-film patterning, and early-stage device prototyping.
Research labs often require non-standard, one-off, or highly precise mask designs, which makes selecting the right supplier crucial.
This guide explains:
- What to look for in a custom mask supplier
- Typical capabilities and tolerances
- How to prepare your design files
- Why research labs prefer specialized fabrication services
- Direct ordering options for universities and R&D teams
What Makes a Good Shadow Mask Supplier for Research Applications?
A qualified supplier should provide:
1. Micro-feature capability
- Minimum feature size: 1–5 µm for stainless steel
- Available alternatives for finer features (nickel, silicon, etc.)
2. Custom thickness and materials
- Stainless steel: 0.03–0.5 mm
- Molybdenum, nickel, or silicon (upon request)
3. Fast turnaround
Research projects often depend on rapid prototyping.
4. Engineering support
A good supplier helps refine:
- Feature sizes
- Thickness selection
- Tolerance optimization
- Manufacturability
5. University-friendly ordering
- Purchase orders (PO)
- Tax-exempt ordering
- Net-30 terms (when available)
- Documented invoice formats
What Information Should Labs Provide When Ordering?
- Your idea! clearly show the design, we will handle everything for your
Why Many Universities Choose Specialized Microfabrication Vendors
1. Ability to produce non-standard micro features
Standard machining shops cannot cut <10 µm features.
2. Experience with scientific projects
Mask suppliers understand:
- alignment holes
- wafer compatibility
- vacuum requirements
- thermal constraints in deposition systems
3. Small batch compatibility
Most labs need 1–5 pieces,.
4. Faster communication for iterative R&D
Scientific projects often require revisions.
