Thermal Oxide Growth Calculator

Use this thermal oxide growth calculator to estimate the time required to grow silicon dioxide (SiO2) on a silicon wafer based on your specified oxide thickness and growth rate. This tool is ideal for semiconductor process planning, furnace scheduling, and research development applications.

Thermal oxide layers are commonly grown using wet oxidation or dry oxidation processes at elevated temperatures. By entering your target oxide thickness and known growth rate, you can quickly determine the approximate oxidation time required for your process.

Calculator Inputs

  • Oxide Thickness (µm) – Desired final SiO2 thickness.
  • Growth Rate (µm/hour) – Measured or recipe-based oxidation rate.

This calculator provides a fast estimation for process setup. For wafers with pre-grown oxide layers, see our Thermal Oxide Silicon Wafers.

Result: Enter both values to calculate.

How Thermal Oxide Growth Works

Thermal oxide is formed when a silicon wafer is exposed to oxygen or steam at elevated temperatures, typically between 800°C and 1200°C. Oxygen or water vapor reacts with the silicon surface to form silicon dioxide (SiO2). This simplified calculator divides the desired thickness by an assumed constant growth rate; actual oxidation kinetics can be nonlinear.
