In-situ ellipsometry studies for the development of a wet cleaning method for image-forming GaAs wafers (EpiClean)

Description

The project develops and validates a chemical, non-mechanical cleaning process to obtain imaging-grade, epitaxy-ready GaAs for small (<1 inch) photocathode wafers used in infrared and night vision equipment.

The Achievable Results

An in-situ spectroscopic ellipsometry method will be created and developed, supported by atomic force microscopy and X-ray photoelectron spectroscopy measurements, with regard to the control process and its parameter boundary values.

The Anticipated Benefit

The project will result in the creation of a cleaning and drying process, as well as initial design for future industrial equipment.
