To optimize efficiency and output, the progress of multiple FOUPs in single wafer deposition machine must be closely monitored. Staff work in close proximity to these machines and prolonged exposure to bright light from tower lights can cause eye strain, leading to physical and mental fatigue. Keep reading to learn how TL30 Basic tower lights solve this application.
Deposition is just one in a number of steps necessary during semiconductor device fabrication. Between processes, silicon wafers are stored in a FOUP (Front Opening Unified Pod) to ensure that the wafers are secure in a controlled environment for safe transport. Multiple FOUPs can be loaded into a single wafer deposition machine at any given time. Once all the wafers have been processed and returned to the FOUP, the FOUP can be removed and a new one loaded into the machine.
Providing clean room staff with clear indication of the status of each FOUP can improve efficiency and increase output. However, eye strain caused by working near bright tower lights for extended periods of time can result in worker fatigue, an increase in errors, and a decrease in productivity.
TL30 Basic tower lights provide easy-to-see status indication, but with a level of light output that is comfortable to the human eye. Staff can work near one or more tower lights for extended periods of time without discomfort or eye strain.
Deployed above each FOUP loaded into the single wafer deposition machine, the TL30 Basic tower lights provide staff with quick, at-a-glance indication of the progress of the FOUPs. When a specific stage in the deposition process is in progress, the corresponding color segment will shine. When the stage is complete, the segment will appear gray to prevent false indication caused by ambient light. When the green segment is lit, the FOUP can be removed and a new one loaded.
