Splet08. nov. 2024 · The wafer fab testing step happens before the dies are cut into chips and packaged. Metrology and inspection are both wafer fab tests. Parametric testing is also done on the wafer level. Related Entities. ... An Overview Of WAT/PCM Data . Published on October 12, 2024. Improving Wafer-Level S-Parameters Measurement Accuracy And … SpletThe Pre-Clean-Module (PCM) is used to clean the wafer prior to deposition. This is a standard technique employing sputter etch technology by applying RF power to the wafer. Typically, the process removes residual water and other molecules and native oxides by adjusting the etching process parameters.

SpletThe most common uses of parametric tests in semiconductor manufacturing include process control monitoring (PCM) and wafer level reliability testing (WLR). PCM focuses on gathered data rather than stressing the device. The duty factor is also an important parameter when multiple pulses are used for a single test. Splet07. nov. 2024 · The powertrain control module, aka PCM, is your vehicle’s brain.
