Building a dedicated substrate platform for next-generation fabs and power devices.
Varix Semicon is developing one of India’s first focused substrate-engineering facilities for high-precision silicon and silicon-carbide wafers—designed for research fabs and pre-production device programs.
A substrate-engineering platform, not just a wafer line.
We are constructing an integrated wafer-substrate facility engineered from day one around real process requirements—tolerances, surface metrics, wafer formats, and material variants—captured directly from leading research institutions and device teams in India.
Silicon wafers
High-precision silicon substrates across key diameters for nanofabrication, device prototyping, and pre-production process development.
Silicon carbide wafers
SiC wafers tuned for power-device workflows where thermal performance, defectivity, and surface integrity are critical.
Process-aligned formats
Wafer formats, flats/notches, and surface specs chosen to align with installed nanofabrication tools across academic and industrial cleanrooms.
Accuracy, surface integrity, and metrology-driven control.
The facility is being designed to support R&D-grade and pre-production wafers with tight control over flatness, roughness, and crystal quality. Metrology is built into the production loop rather than treated as an afterthought.
Engineered process chain
From slicing and shaping to grinding, lapping, and polishing, each stage is defined around measurable tolerances and repeatability targets.
Compatibility with your tools
Wafers are specified for compatibility with common lithography, etch, deposition, and packaging workflows in both academic and industrial nanofabrication environments.
Metrology-driven operations
Inline and offline metrology guide process adjustments, helping maintain consistency across lots rather than relying on manual judgment alone.
Built in close collaboration with India’s research and device teams.
As we refine our production roadmap, we are working closely with leading Indian research institutions and power-device programs so that the substrate platform aligns with real fab-floor requirements—not just theoretical specifications.
Requirement mapping
Tolerances, wafer formats, and material variants captured directly from nanofabrication teams to shape our baseline specifications.
R&D and pre-production
Focused on bridging the gap between lab-scale experiments and pre-production device runs in India’s emerging fab ecosystem.
Domestic substrate capability
Long-term objective: a reliable, domestic source of Si and SiC substrates that support India’s semiconductor ambitions.
From pilot to stable supply.
We are targeting a staged ramp-up where process capability is validated alongside early partners before scaling into wider availability.
Finalizing wafer specifications based on input from research fabs, power-device teams, and nanofabrication cleanrooms.
Pilot wafer runs with tight metrology feedback loops to lock in surface integrity, flatness, and defectivity targets.
Opening up to a wider set of R&D and pre-production customers once process stability and logistics are validated.
