Photo-assisted hydrogenation process

Apparatus and method are provided for hydrogenating semiconductor or other materials by ultraviolet (UV) radiation in the presence of hydrogen. Hydrogen uptake may be optimized by selection of temperature and wavelength of the UV radiation. Patterned areas may be selectively hydrogenated, such as me...

More Information
Summary:Apparatus and method are provided for hydrogenating semiconductor or other materials by ultraviolet (UV) radiation in the presence of hydrogen. Hydrogen uptake may be optimized by selection of temperature and wavelength of the UV radiation. Patterned areas may be selectively hydrogenated, such as mesas in Avalanche Photodiode Arrays.
