Semiconductor Utilization

Site Explanation: Semiconductor Utilization Semiconductor utilization describes how much qualified manufacturing capacity is being used, but it can be measured at the fab, process-node, tool, wafer-start, output, or revenue level. These measures are not interchangeable. The preferred physical measure is actual wafer starts divided by maximum sustainable wafer-start capacity over the same period. Maximum sustainable capacity should reflect normal maintenance, qualified tools, process mix, and ach

Fab Utilization

actual/capacity*100

Actual wafer starts wafers

Maximum sustainable wafer starts wafers

Derived result
—

Use the same fab, node family, and period.

Good Die Output

wafers*dies*(yield/100)

Wafer starts wafers

Gross dies per wafer dies/wafer

Die yield %

—

Yield is entered as a percentage.

Shipment-to-Capacity Proxy

ship/capacity*100

Reported shipments wafers

Reported capacity wafers

Derived result
—

This is a proxy, not disclosed fab utilization.

12-inch Equivalent Wafers

wafers*(diameter/12)^2

Native wafer count wafers

—

Physical-area comparison only; it is not economic or process-node equivalence.
