Wafer procurement is a complex process that involves a number of aspects, companies need to focus on the following points to ensure that the purchased wafers meet production requirements and control costs:

Wafer quality: The maximum power point of the wafer, purity, resistivity, thickness, flatness, surface defects, open-circuit voltage and other parameters directly affect the performance and yield of the final product.

Supplier Reputation: Choose suppliers with good reputation and stable supply capability, as well as production qualification and advanced production process, to avoid the risk of shortage or broken supply.

Price and cost: The price of silicon wafers is affected by market supply and demand, raw material cost, production technology and other factors. Enterprises should reasonably assess and control the procurement cost through value analysis, cost analysis, target cost method and other methods.

Supply chain stability: Ensure the stability and reliability of the supply chain to avoid production interruption caused by supplier problems. Long-term cooperation method and supply chain management method can help enterprises establish a stable supply chain.

Technical compatibility: The size of the wafer, doping type and other parameters need to be matched with the production equipment and technical route of the enterprise to ensure a smooth production process.

The price of silicon wafers is affected by quality, power, specifications, size, packaging and many other aspects, and the balance between price and quality needs to be considered comprehensively.
The company is also working on the strategy and inventory management to cope with the market fluctuation and supply chain risk.

Through the above methods, enterprises can effectively control procurement costs and improve overall competitiveness while ensuring the quality of silicon wafers.
