Thermal Oxidation of Silicon

Online calculators for thermal oxidation can be used to estimate the oxidation time for a desired oxidation thickness. Please see the Calculators + Utilities page for links to these oxidation calculators.

Using the Stanford Leland Jr. "Advanced Silicon Thermal Oxide Thickness Calculator", we have determined the following simulation parameters to predict oxidation times.

1050°C Dry Oxidation

  • Partial Pressure = 1.09
  • <100>, 1050°C, 10Å Native Oxide, no dopants

1050°C Wet Oxidation

  • Partial Pressure = 1.12
  • <100>, 1050°C, 10Å Native Oxide, no dopants

Wafer Substrate Bonding

Numerous research groups perform wafer bonding using either the Suss Wafer Bonder or a custom graphite fixture and any one of numerous ovens, such as the N2-purged Wafer Bonding Furnace (with glove box) or N2-purged Blue M oven.

The EVG Plasma Activation system and Goniometer allow for surface prep/inspection prior to bonding.
