Cost of Setting Up a SiC Power Devices Manufacturing Plant:

Operating Cost Structure:

Understanding the operating expenditure (OpEx) is crucial for effective financial planning. The cost structure includes:

• Raw Materials: 40-50% of total OpEx
• Utilities: 20-28% of OpEx
• Other Expenses: Labor, packaging, transportation, maintenance, depreciation, taxes

Raw materials at 40-50% of operating costs, with SiC substrates/wafers as the primary and most cost-critical component, along with epitaxial precursor gases (silane SiH4, propane C3H8), dopant gases (nitrogen, aluminum), photoresist, and etch gases. Utilities at 20-28%. By the fifth year, the total operational cost is expected to increase substantially due to factors such as inflation, market fluctuations, and potential rises in the cost of key materials. Additional factors, including supply chain disruptions, rising consumer demand, and shifts in the global economy, are expected to contribute to this increase. Long-term contracts with reliable suppliers will help mitigate price volatility and ensure a consistent supply of materials.

Capital Investment Requirements:

Setting up a SiC power devices manufacturing plant requires substantial capital investment. The total depends on plant capacity, technology, and location.

Land and Site Development: Location must offer easy access to key raw materials such as SiC substrates/wafers, epitaxial precursor gases (silane SiH4, propane C3H8), dopant gases (nitrogen, aluminum), photoresist, and etch gases. Proximity to target markets will help minimize distribution costs. The site must have robust infrastructure, including reliable transportation, utilities, and waste management systems. Compliance with local zoning laws and environmental regulations must also be ensured.

Machinery and Equipment: Machinery costs account for the largest portion of total capital expenditure. Essential equipment includes:

• Epitaxial reactors (CVD systems)
