Due to white phosphorus’s extreme reactivity with oxygen, Veeco’s Phosphorus Recovery System (PRS) provides a safe, efficient means of trapping and neutralizing white phosphorus from the growth module prior to venting an MBE system for maintenance and/or source reloading. The process is controlled and closely monitored through Veeco Molly® Growth Control Software.The Veeco PRS is available in two models to accommodate low-volume or high-volume manufacturing environments.
The Veeco Phosphorus Valved Cracker Temperature Controller, available for existing and new phosphorus valved crackers, ensures accurate and stable white zone temperature instabilities that can arise from changing environmental conditions such as air temperature or water-cooling temperature.
The temperature controller works by maintaining a constant white zone temperature within ±0.05°C, resulting in phosphorus flux stabilities <±1%. In addition, the temperature controller greatly simplifies the valve cracker process settings by enabling the user to accurately set the temperature of the white zone as opposed to manually setting the white zone air flow.
