Available Metal Coatings & Engineering Functions
We utilize advanced Physical Vapor Deposition (PVD) and sputtering techniques to coat ultra-thin glass with a variety of high-purity metals, tailored to your application:
- Gold (Au) + Ti/Cr Adhesion Layer: Provides ultimate chemical inertness, biocompatibility, and IR reflectance. Highly used in Surface Plasmon Resonance (SPR) biosensors and flexible transparent electrodes.
- Chromium (Cr): Offers superior optical density (OD) for flexible photomasks, calibration targets, and ultra-lightweight light-blocking apertures.
- Copper (Cu): Essential for high-density flexible circuits, RF antennas, and advanced semiconductor packaging (metallized glass interposers).
- Aluminum (Al) & Silver (Ag): Delivers broadband reflectivity for ultra-lightweight space mirrors and flexible optoelectronics.
- Platinum (Pt) & Titanium (Ti): Highly durable electrodes for microfluidics, lab-on-a-chip devices, and harsh chemical environments.
Overcoming the Fabrication Challenges (Our Advantage)
Coating and processing glass thinner than a human hair introduces severe manufacturing challenges. Standard coaters often warp the glass, and standard dicing shatters it. Here is how we guarantee industrial reliability:
- Stress-Free Deposition (Zero Warpage): Metal films introduce surface stress that can cause ultra-thin glass to curl or bow. We strictly control deposition temperatures and vacuum parameters to ensure low-stress coatings, keeping the thin flexible substrate perfectly flat.
- Flawless Adhesion: Metals like gold and copper do not bond natively to glass. We deposit ultra-thin (nanometer-scale) Titanium (Ti) or Chromium (Cr) adhesion layers before the functional metal, ensuring the film survives tape tests, bending, and harsh environments without delamination.
- Micro-Precision Laser Dicing: Cutting metal-coated ultra-thin glass mechanically causes edge chipping and film peeling. We utilize ultrashort pulse lasers (picosecond/femtosecond) to cut coated substrates with zero thermal damage, clean edges, and no coating disruption.
- Photolithography & Patterning: Need specific electrode designs? We can pattern the metal layers directly on the ultra-thin glass with micron-level resolution using wet or dry etching techniques.
High-Tech Applications
Our metal-coated ultra-thin glass is driving miniaturization and flexibility across high-tech sectors:
- Flexible Electronics: Transparent heaters, EMI shielding, and wearable medical sensors.
- Advanced IC Packaging: Glass core substrates and metallized edges for hermetic soldering.
- Bio-Tech & Microfluidics: Conductive micro-arrays and impedance sensors on flexible lab-on-a-chip systems.
- Aerospace & Optics: Deformable mirrors and ultra-lightweight IR reflectors for satellites.

Because handling and coating ultra-thin glass requires extensive engineering prep, clear specifications are vital for an accurate quote.
To help us evaluate your project, please provide:
- Base Glass & Thickness: (e.g., SCHOTT AF32 50μm, or standard UTG 100μm).
- The Metal Stack: (e.g., 10nm Ti Adhesion Layer + 100nm Au Layer).
- Dimensions & Tolerances: Substrate size, and whether it requires custom dicing.
- Delivery Format: We highly recommend delivery on a PET/OCA carrier film for safe unboxing and automated assembly line handling.
