Semiconductor Test Cost with devices or die tested of 130,000 devices: a worked example

What does the result look like when devices or die tested reaches 130,000 devices? The full calculation is worked below with real intermediate numbers. a test engineer or estimator needs test cost for die, packages, or modules

The inputs for this scenario

  • Devices or die tested: 130,000 devices (raised for this scenario; the documented default is 52,000)
  • Variable semiconductor test cost: 0.08 $ / device (unchanged)
  • Test program or setup cost: 1,800 $ (unchanged)
  • Tester, handler, socket, and overhead cost: 2,400 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total semiconductor test cost = devices or die tested × variable semiconductor test cost + setup + overhead) to the inputs above produces each figure below.
  • At this operating point the engine returns 14,600 $ for total semiconductor test cost, the number this scenario is built around.
  • At this operating point the engine returns 0.11 $ / device for semiconductor test cost per device.
  • At this operating point the engine returns 10,400 $ for variable device test cost.
  • At this operating point the engine returns 4,200 $ for program, tester, socket, and overhead adders.

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 74.64% above the baseline at 14,600 $.
  • A figure at this level is achievable when devices or die tested is genuinely sustained, not just peaked for a shift. It assumes a flat per-device variable cost and a single overhead bucket, so it will not capture yield fallout, multisite parallelism gains, or retest loops that change effective cost per good die.

Results at a glance

  • Total semiconductor test cost: 14,600 $ (headline result)
  • Semiconductor test cost per device: 0.11 $ / device
  • Variable device test cost: 10,400 $
  • Program, tester, socket, and overhead adders: 4,200 $
