Free process calculators

Paste your measured numbers and get the same formulas side by side that the articles explain. No sign-up, and nothing leaves your browser.

• Film Thickness Uniformity CalculatorPaste your thickness measurements and see half-range, range, and sigma uniformity in a single view. The same wafer data produces three different percentages — this tool shows all of them so you can compare directly.
• ALD GPC & Temperature Window CalculatorEnter film thickness and cycle count to get growth per cycle, or input GPC-vs-temperature data to identify the temperature window. Both calculations run in your browser with nothing sent to a server.
• Etch Selectivity CalculatorCompare rate-based and consumption-based etch selectivity side by side, and estimate how much mask you need for a given etch depth. Enter your data below — everything is calculated in your browser.
• Step Coverage CalculatorEnter film thicknesses measured at the top surface, sidewall, and feature bottom. This calculator returns step coverage ratios, aspect ratio, and a pass/fail check against your minimum thickness requirement.
