About Semiconductor Tools

Semiconductor Tools is an independent engineering utility site for semiconductor process and equipment engineers.

The site provides practical calculators, reference tables, and technical notes for semiconductor manufacturing topics such as vacuum systems, gas flow conversion, MFC basics, pumpdown estimation, outgassing, conductance, and process utility calculations.

The site is operated by an engineer with practical experience in semiconductor process and equipment engineering. The goal is to make commonly used engineering calculations easier to understand, verify, and apply in daily technical work—without replacing vendor manuals, site safety procedures, or qualified engineering judgment.

What we publish

• Free engineering calculators with formulas, assumptions, and limitations
• Technical articles explaining concepts used in the tools
• Reference data based on public sources such as NIST Chemistry WebBook

Editorial standards

Content is maintained by the Semiconductor Tools Editorial Team. We follow our Editorial Policy for formula transparency, references, and corrections.

Important notice

All tools and articles are intended for educational and preliminary engineering reference. They should not replace equipment manuals, vendor specifications, safety procedures, or qualified engineering judgment. See our Disclaimer for details.
