300 mm
Target long-term wafer capability focus
Company
Precision first. Scale with purpose.
ST Silicon Materials is being built with a disciplined, phased strategy: learn the process, define the right product pathway, establish quality systems, and create an India-based wafer manufacturing platform with global standards in mind.
Surface engineering
Evaluating grinding, lapping, polishing, wet processing, cleaning, surface damage removal and other preparation steps needed for semiconductor-quality wafers.
Process engineeringGlobal ecosystem building
Building relationships with equipment makers, crystal suppliers, research institutions, semiconductor companies and strategic partners across major semiconductor regions.
PartnershipsStrategic focus
From process knowledge to product capability.
The business is being structured around a staged manufacturing model that prioritizes technical understanding, measurable quality and realistic scale-up over premature over-expansion.
What we are building
A disciplined silicon wafer manufacturing platform.
The immediate goal is to build a credible manufacturing foundation—one that can evolve from project definition and supplier validation into controlled wafer-processing capability and then into a larger manufacturing platform.
