Deposition of III-V semiconductor materials

摘要

A low temperature procedure for depositing III-V semiconductor materials that offers the possibility of higher deposition rates together with abrupt junction formation has been found. This process involves the irradiation at a deposition substrate with a high power density radiation source of deposition gases such as organometallic materials, e.g., trimethyl gallium and trimethyl indium. By utilizing a sufficiently high power density, multiphoton processes are induced in the deposition gas that, in turn, lead to advantageous deposited materials.
