Hosur-based Raana Semiconductors is in advanced discussions to raise ₹100 crore in a Series A round to upgrade its Czochralski (CZ) crystal-growth systems, enhancing silicon production capacity for semiconductor and solar applications.
- Plans to raise ₹100 crore led by an Indian VC in Series A
- Funds to upscale CZ silicon crystal-growth tech from 6-inch to 12-inch
- Targets solar manufacturers next, then semiconductor customers
What happened
Raana Semiconductors is in advanced talks to raise about ₹100 crore (around $10.4 million) in its Series A funding round. The round is expected to be led by an Indian venture capital firm contributing ₹50-60 crore, with participation from seven to eight other investors and potential follow-on investments from existing backers. The startup aims to close this round by October 2026.
The newly raised capital will primarily be directed toward scaling Raana’s Czochralski (CZ) crystal-growth equipment from a 6-inch to a 12-inch system. Additionally, the funds will support fine-tuning the silicon crystal-growth process and developing a localized vendor ecosystem to manufacture the equipment domestically.
Why it matters
Raana’s CZ technology is critical for producing monocrystalline silicon, a high-purity material essential for high-performance semiconductor chips and solar cells. By scaling the equipment to 12-inch wafers, Raana plans to meet increasing demand from solar manufacturers initially, with a strategic long-term focus on the semiconductor industry.
Currently, the company’s core revenue comes from national laboratories and defence organizations like DRDO, BARC, and others, showcasing its strategic role in India’s technology ecosystem. Expanding equipment capacity and refining processes with this funding will enable Raana to support India’s push toward localized semiconductor manufacturing and solar production.
What to watch next
Raana intends to complete the Series A round closing by October 2026 and begin implementation of the scaled 12-inch CZ crystal-growth system. The startup plans to develop a pilot silicon manufacturing plant in Tamil Nadu, further strengthening its domestic footprint in semiconductor materials production.
Future developments will include validating the new system through testing and demonstration for customers in the solar and semiconductor sectors. Success in scaling production and establishing a supplier ecosystem could position Raana as a key domestic player in India’s growing semiconductor supply chain ambitions.
