Semiconductor Test Cost with devices or die tested of 26,000 devices: a worked example

This worked example runs the semiconductor test cost numbers for a tougher week than the baseline: devices or die tested of 26,000 devices instead of the typical 52,000 devices. Estimate semiconductor test cost from tested devices or die, variable test cost, setup cost, and overhead.

The inputs for this scenario

  • Devices or die tested: 26,000 devices (the input this scenario stresses; the baseline uses 52,000)
  • Variable semiconductor test cost: 0.08 $ / device (held at the documented default)
  • Test program or setup cost: 1,800 $ (held at the documented default)
  • Tester, handler, socket, and overhead cost: 2,400 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total semiconductor test cost = devices or die tested × variable semiconductor test cost + setup + overhead.
  • Total semiconductor test cost works out to 6,280 $ at these inputs, and this is the headline figure for the scenario.
  • Semiconductor test cost per device works out to 0.24 $ / device at these inputs.
  • Variable device test cost works out to 2,080 $ at these inputs.
  • Program, tester, socket, and overhead adders works out to 4,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where devices or die tested sits at 52,000 devices and the headline result is 8,360 $, this scenario comes in 24.88% below the baseline at 6,280 $.
  • Use it when quoting a test insertion to a fabless customer, comparing OSAT bids, or deciding whether a test-time reduction project pays back across the expected volume. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total semiconductor test cost: 6,280 $ (headline result)
  • Semiconductor test cost per device: 0.24 $ / device
  • Variable device test cost: 2,080 $
  • Program, tester, socket, and overhead adders: 4,200 $
