| Outline of Final Research Achievements |
An AlAs selective oxidation shape control technology by intermixing-method was proposed as a fabrication technology of GaAs based photonic devices. The conventional AlAs selective oxidation technology showed the same oxidation rate in a same wafer. By applying intermixing technology, the effective reduction of the AlAs layer thickness could be achieved, and the reduction of the oxidation rate in specific area was succeeded. This means that the proposed technology is useful as a complex shape formation technique. In addition, a basic numerical simulation tool for estimating the oxidation shape was built.
