Direct Answer
Silicon wafer makers grow crystals and slice, polish and sell the disks that chips are built on, in diameters up to 300 millimeters. Long-term supply agreements and a few global producers define the market, and pricing follows chip demand.
Industry Overview
Silicon Wafers sits within the information technology sector. The first numbers to compare across companies here are wafer shipments in area, average selling price and capacity utilization. The outside forces that move them are listed under Primary Macro Drivers.
Key Industry Metrics
- Wafer shipments in area: Total wafer surface area sold, not the number of disks. Area normalizes for diameter, so it shows true volume demand from chipmakers, separate from price.
- Average selling price: Revenue earned for each unit of wafer area sold. Rising prices show tight supply and strong demand, while falling prices point to oversupply or weaker chip production.
- Capacity utilization: The share of crystal-growing and polishing capacity in use. High utilization supports prices and returns, while low utilization leaves fixed costs spread over fewer wafers.
- Long-term agreement coverage: The portion of volume sold under multi-year supply deals. Higher coverage gives revenue visibility across chip downturns, though it can limit pricing gains in strong years.
- Gross margin: Revenue left after crystal growth, slicing and polishing costs. It moves with utilization and price, so margins swing more than demand in the cyclical chip market.
Primary Macro Drivers
- Semiconductor production volumes: Every chip starts on a wafer, so the output of chipmakers sets wafer shipments in area and utilization.
- 300-millimeter capacity additions: Newer fabs use larger wafers, so adding 300-millimeter capacity shifts demand toward the largest diameter and its long-term contracts.
- Memory and logic cycles: Memory and logic makers swing wafer purchases with their own pricing cycles, causing visible changes in shipments and average selling price.
- Power and compound-semiconductor wafers: Power devices and special substrates need different wafer types, adding demand and often higher prices outside standard silicon.
Major Risks
- Cyclical swings: Shipments and prices fall in downturns while crystal growth plants carry fixed cost; watch shipments in area, price trends and utilization.
- Customer inventory adjustments: Customers that hold too much stock pause orders even when chip output is steady, so shipments fall faster than end demand; watch inventory commentary.
- Capital intensity: Crystal growth and polishing capacity takes years and large spending to add, so weak utilization raises unit cost; watch capital spending and utilization.
- Concentration among a few producers: A small number of suppliers and buyers means limited pricing options on either side; watch long-term agreement coverage and customer share of sales.

Finding Companies in Silicon Wafers
The SEC's Standard Industrial Classification has no code that describes silicon wafers as a group, so this profile does not list companies for it. Filers are classified by their main business, and a company in this industry may sit under a broader code.
To find individual companies, use the company directory and the information technology hub. Nothing here is a list of recommendations.
