Process Control Data are standardized processes, run by the NanoFab, allowing for day-to-day or year-by-year comparisons of a tool's performance at the process level. This is similar Statistical Process Control (SPC).

These are the same links are found on individual tool pages, in the <<tool page>> > Process Control section.

Data are collected by our Process Group Interns and reviewed by Process Group Staff.

Deposition (Process Control Data)

Process Control data for various deposition tools in the lab.

PECVD #1 (PlasmaTherm 790)

PECVD #2 (Advanced Vacuum)

ICP-PECVD (Unaxis VLR Dep)

Ion Beam Sputter Deposition (Veeco Nexus)

Old Data (Pre 2022)

Old data in a different format can be found below:


Etching (Process Control Data)

Process Control data for various dry etching tools in the lab.

PlasmaTherm SLR Fluorine Etcher

SiO2 Etching (FL-ICP Process Control)

We have found that SiO2 etching is fairly insensitive to chamber condition.

Old SiO2 Process Control Data

Si Etching (FL-ICP Process Control)

This Si etch is much more sensitive to chamber condition, allowing us to detect chamber contamination faster.
