At Micro to Nano Solutions, we support the design and fabrication of advanced optoelectronic devices by leveraging accessible, state-of-the-art micro- and nano-fabrication infrastructure. Our capabilities enable the transformation of functional designs into working devices that generate, guide, modulate, and detect light with high precision.

Optoelectronics forms the technological backbone of modern optical communication, sensing, imaging, and display systems. Successful device realization requires tight control over materials, dimensions, interfaces, and optical alignment—all of which are addressed through our comprehensive fabrication workflow.

Complete Optoelectronic Fabrication Workflow

We provide end-to-end process integration, covering the full lifecycle of optoelectronic device fabrication:

1. Device & Mask Design

• Photomask and layout design for optical and electrical alignment
• Process flow development tailored to optical performance and yield
• Design optimization for waveguides, electrodes, and active regions
  

2. Lithography

• UV photolithography for scalable optoelectronic structures
• Electron-beam lithography for sub-micron and nanophotonic features
• Direct-write lithography for rapid iteration and prototyping
  

3. Thin-Film Deposition

• PECVD / LPCVD for dielectric and optical passivation layers
• Sputtering & E-beam evaporation for metals and reflective coatings
• ALD for conformal, thickness-controlled optical and insulating films
  

4. Dry & Wet Etching

• Reactive Ion Etching (RIE) and ICP-RIE for high-aspect-ratio optical structures
• Selective wet etching for material release and surface definition
• Precision control of sidewall roughness critical for low-loss photonic devices

5. Wafer Processing & Integration

• Wafer thinning, polishing, and surface preparation
• Wafer bonding and hybrid integration for multi-material optoelectronic platforms
• Dicing and device-level preparation for testing and packaging
  

6. Metrology & Characterization

• Optical and electron microscopy for feature inspection
• Thin-film thickness and uniformity measurements
• Electrical and optical probing readiness for performance validation
  

Supported Optoelectronic Devices

Our fabrication platform is suitable for a wide range of optoelectronic and photonic components, including:

• Photodetectors and optical sensors
• Waveguides and integrated photonic circuits
• Optical modulators and switches
• LED, micro-LED, and light-emitting structures
• Optical interconnects and on-chip photonics

These devices are developed with a focus on low optical loss, high alignment accuracy, and reliable electrical-optical coupling.

Why It Matters

Optoelectronic devices demand tighter tolerances and deeper process integration than conventional electronics. By combining advanced fabrication tools, flexible process development, and small-volume production, M2N Solutions enables clients to:

• Rapidly prototype and validate optoelectronic designs
• De-risk fabrication challenges before scaling
• Transition concepts into application-ready devices

From early-stage R&D to application-driven prototyping, we help bridge the gap between design intent and functional optoelectronic hardware.
