Semiconductor & Optoelectronics Solutions

From substrate engineering to pattern transfer — enabling the next breakthrough in power, RF, and photonic integration.

A full-stack material platform covering wide-bandgap substrates, advanced packaging carriers, photomasks, and functional wafers.

Semiconductors and photonics are converging on a unified silicon/non-silicon platform. From boosting power density in 800V e-drive systems, to breaking bandwidth bottlenecks in AI data center optical interconnects, to micron-scale precision in 3D advanced packaging — materials define the ultimate performance frontier.

Minn Optics supplies global manufacturers with a complete portfolio: device-grade substrates (SiC, LiNbO₃, sapphire), process carriers (glass, quartz wafers), and lithography masters (photomask blanks). We help you turn physical limits into product advantages across these key tracks.

Explore by Application Domain

Power Semiconductors & High-Frequency RF

Silicon devices degrade under high temperature, voltage, and frequency — pushing thermal and efficiency budgets to the limit.

Minn Optics Approach

  • Ultra-low defect 4H-SiC wafers for MOSFETs and Schottky diodes
  • Low-warp sapphire wafers as alternative GaN-on-SiC carriers for RF PAs

Key Applications

  • EV traction inverters, OBC, DC-DC converters
  • Solar inverters & energy storage
  • 5G/6G base station GaN RF power amplifiers

Core Advantages

  • Micropipe density <0.5/cm², consistent crystal quality
  • High thermal conductivity & wide bandgap reduce switching loss

Advanced Packaging & MEMS System Carriers

3D stacking of AI/HPC chips demands high-density TGV substrates; ultra-thin wafer handling requires extreme flatness and CTE matching.

Minn Optics Approach
