Latest Patents
Oelhafen holds a patent titled "Intermediate passivation and cleaning of compound semiconductor surfaces." This innovative patent addresses the challenges associated with crystalline compound semiconductors. The process involves passivating a GaAs crystal with a surface layer of arsenic to prevent oxide formation that could interfere with further processing. The arsenic layer is created through exposure to light with a photon energy greater than 1.8 eV, while the GaAs is immersed in a 1:1 HCl:H2O solution for 10-30 minutes. This method allows the processed GaAs crystal to be stored and handled in air, with the arsenic layer removable by low-temperature baking.
