Setting up a SiC power devices manufacturing plant in India presents a compelling investment case, driven by rising adoption of 800V EV architectures, expansion of renewable power installations, AI-driven data centers, and smart grid modernization. SiC power devices are advanced semiconductor components used to control and convert electrical power, made from a durable compound of silicon and carbon that allows them to operate at much higher voltages, temperatures, and frequencies than conventional silicon alternatives.
India’s push toward semiconductor self-reliance, electric mobility, and domestic electronics manufacturing under Make in India and PLI schemes is strengthening demand for locally produced power semiconductors. Automotive OEMs, industrial equipment manufacturers, and power electronics companies are increasingly seeking localized semiconductor supply chains, creating a strategically sound opening for regional manufacturers.
This investment benefits from strong policy support under Make in India and PLI schemes, cost-competitive manufacturing economics, and steady demand from EV, renewable energy, and industrial automation sectors. With gross margins of 30–42% and net margins of 10–20%, it offers a credible path to break-even viability.
What are SiC Power Devices?
SiC power devices are advanced semiconductor components used to control and convert electrical power. Made from a durable compound of silicon and carbon, SiC belongs to the “wide-bandgap” family of materials, allowing devices to operate at much higher voltages, temperatures, and frequencies than conventional silicon alternatives. By minimizing energy waste and reducing power conversion losses, SiC technology enables dramatic improvements in energy efficiency, translating to smaller, lighter, and more compact electronic designs.
The SiC power devices manufacturing process uses epitaxial growth, photolithography, ion implantation, etching, thin-film deposition, metallization, wafer thinning, dicing, packaging, and electrical testing as its core stages. End-use industries served include electric vehicles, renewable energy, industrial automation, power transmission & distribution, consumer electronics, aerospace & defense, railways, and telecommunications.
Cost of Setting Up a SiC Power Devices Manufacturing Plant in India
Cost depends on capacity, technology, location, automation, and regulatory compliance.
1. Capital Expenditure (CapEx)
Total capital investment for the plant depends on capacity, technology, and location, covering land acquisition, site preparation, and necessary infrastructure. Land and site development — including registration, boundary development, and related charges — forms a substantial part of the investment, and investors can evaluate industrial estates or designated zones offering robust infrastructure, transportation, and utilities, while ensuring compliance with local zoning and environmental regulations.
Machinery costs account for the largest portion of capital expenditure, with scale of manufacturing and automation level determining the total cost.
Key machinery required includes:
- Epitaxial reactors (CVD systems)
- Photolithography systems
- Ion implantation equipment
- Oxidation furnaces
- Plasma etching systems
- Thin-film deposition equipment (PVD/CVD)
- Metallization systems
- Chemical mechanical polishing (CMP) tools
- Wafer probing systems
- Wafer dicing machines
- Die bonders
- Wire bonders
- Molding and packaging systems

2. Operational Expenditure (OpEx)
Raw material cost is the largest component of operating expenses. SiC wafers, epitaxial precursor gases (silane SiH4, propane C3H8), dopant gases (nitrogen, aluminum), photoresist, and etch gases together account for approximately 40–50% of total OpEx, making long-term supplier contracts essential to mitigate price volatility.
Utility cost accounts for approximately 20–28% of OpEx. Other operating costs include transportation, packaging, salaries and wages, depreciation, taxes, and maintenance.
By the fifth year, total operational cost is expected to rise substantially due to inflation, market fluctuations, rising raw material costs, supply chain disruptions, and shifts in the global economy.
3. Plant Capacity
The proposed facility is designed with an annual manufacturing capacity ranging between 10,000–50,000 wafers, enabling economies of scale while maintaining flexibility. Capacity can be customized based on investor requirements, and profitability generally improves with higher capacity utilisation.
4. Profit Margins and Financial Projections
Financial projections cover ROI, profitability, and long-term sustainability, based on capital investment, operating costs, capacity utilization, pricing trends, and demand outlook. Gross profit margins typically range between 30–42%, while net profit margins range between 10–20%. Payback period, liquidity, and net present value (NPV) figures form part of the full financial analysis.
