Fully
automatic single cassette loader, up to 8", with auto-handling, individual
lamp sensors, automatic irradiation time control, UV status indicator, UV
intensity monitoring, cassette status indicator.
Fully Automatic - No operator contact with wafer frame during processing. Operator inserts wafer cassette into system, initiates process, then removes completed wafer cassette at the end of process cycle.
Continuous Processing Cycle - No wasted handling time between UV irradiation of individual wafer frames. Intelligent transport system maintains continuous wafer frame presence over UV lamps.
PC-control -
Friendly WindowsTM interface. System displays
UV intensity, process time, etc. in real-time. Quality Assurance data stored
in process log.
Safe, Ozone-free UV Irradiation - Uses optimized wavelength for UV
curing process. Low-pressure mercury vapor lamps do not require special
cooling or nitrogen to counteract harmful ozone emissions. Provides safe operating environment and economical utility requirements.

1. Wafer cassette containing frames with mounted
substrates awaiting UV exposure is placed on cassette
loading adaptor.
2. Operator selects desired pre-programmed UV exposure
recipe and starts the process cycle.
3. System scans wafer cassette to determine which slots
are populated. This information is used to optimize
material handling during processing cycle.
4. System automatically transports wafer/frames from
cassette to UV irradiation station, where frame is
processed according to programmed recipe.
5. During UV irradiation of frame, next frame is positioned
in standby position, so that when completed frame is
transported back to original location in cassette, the next
frame immediately receives UV irradiation. In this
manner, total cassette process cycle time is optimized.
6. When all wafer frames have been irradiated and returned
to cassette, the system indicates process completion on
monitor screen and signal tower. Operator removes
cassette to complete the process cycle.
