Silicon
The semiconductor substrate.
Czochralski-grown single crystal Silicon boules at semiconductor-grade purity. Substrates for IC fabrication, power electronics, solar cells, and MEMS devices.
Germanium
IR optics & defence sensing.
High-purity single crystal germanium for infrared optics, FLIR thermal imaging, night vision systems, and multi-junction space solar cells.
Nd:YAG
The defence laser crystal.
Neodymium-doped Nd:YAG single crystals for solid-state laser systems. Gain medium for defence range finders, target designators, and medical laser applications.
Lithium Niobate
Photonics, piezoelectrics & quantum.
Czochralski-grown Lithium Niobate single crystals with electro-optic and piezoelectric properties. Used in 5G SAW filters, fibre-optic modulators, acoustic wave sensors, and quantum photonic circuits.
Our Technology
Automatic CZ Crystal Growth System
RF-heated Czochralski pullers with fully automated diameter control, growing Silicon, Germanium, Nd:YAG, and Lithium Niobate single crystals for semiconductor, defence, and photonics applications. Temperature stability is maintained within ±0.1 °C. Pull speed is controlled to nanometre precision. A single run can take 48-72 hours. The margin for error is zero.

For Policy Makers
Why single crystals are a strategic material.
Single crystals sit at the very beginning of the semiconductor, defence, and atomic value chains. India has zero domestic production capacity today. Raana is changing that.
Eliminating Import Dependence
India imports 100% of its single-crystal substrates - Silicon, Germanium, Nd:YAG, and Lithium Niobate - from the US, Japan, Russia, and China. A single supply-chain disruption can halt domestic semiconductor, defence, and atomic programmes. Raana is building the country's first Czochralski crystal manufacturing line to close this gap.
Defence & Strategic Autonomy
Nd:YAG and Germanium crystals power laser range-finders, target designators, and directed-energy systems across the Indian armed forces. Indigenous crystal supply removes foreign-vendor dependency from classified defence platforms - a national-security imperative.
India Semiconductor Mission - 2.0
India 2.0 envisions a fully self-reliant semiconductor ecosystem - where critical materials, precision equipment, and advanced manufacturing are built domestically. By investing in indigenous equipment and material supply chains, the mission strengthens every layer of the value chain - from upstream materials to downstream assembly.
Economic Multiplier
Every ₹1 of crystal substrate enables ₹20-50 of downstream value in wafer fabrication, device manufacturing, and system integration. Localising crystal growth seeds an entire high-value supply chain - from raw boules to polished wafers to finished semiconductor and atomic devices - creating deep-tech manufacturing jobs in India.
