Deeptech startup Raana Semiconductors Pvt. Ltd. (RSPL) has raised $3 million in a seed round led by Equirus Innovatex Fund and Artha Venture Fund, with participation from IvyCap Ventures, PointOne Capital, CIIE Initiatives (IIMA Ventures) and angel investor Garimella Laxminarayana. 

This marks the company’s first institutional funding and was raised through a pure equity round.

The proceeds will be used to accelerate R&D and product development of indigenous Czochralski (CZ) silicon ingot growth systems. The firm is initially focusing on building systems capable of producing 10–12 inch solar-grade silicon ingots, with a long-term roadmap toward semiconductor-grade wafers.

Founded over a decade ago, Raana Semiconductors works on CZ-based crystal growth equipment and single-crystal materials. It develops and supplies turnkey silicon ingot growth systems, including installation, commissioning, and after-sales support, which are typically sourced from overseas suppliers.

RSPL is currently the only private Indian company focused exclusively on CZ crystal growth equipment. The firm has worked with institutions such as BARC and IGCAR and has also executed projects under the Ministry of Defence’s iDEX programme.

For FY26, the company has secured confirmed orders worth Rs 12 crore from government departments and national laboratories. Raana Semiconductors plans to commercialise its solar-grade CZ systems within the next 18 months, targeting large-scale silicon ingot production for domestic solar manufacturers.
