Photoresist Spin Coat Benches
|
About
The facility contains 3 stainless steel solvent benches for photoresist spin coating. The benches consist each of 2 integrated Headway PWM32 series photoresist spinners. Overhead and foot controls are provided. 8 preprogrammed recipes and 2 user-programmable recipes are offered. Automatic wafer lifting and centering stations are offered for spinning large wafers up to 8” in diameter. 6” or 8” Cee ultra-flat hotplates with 0.1°C temperature stability are preset for standard resist bake temperatures (90, 95, 100, 105, 110, 115°C). Other user-changeable hot plates are also provided. Nitrogen guns are also on both sides of the bench. Large resist bottles are stored in a refrigerator amd small user bottles are stored by group in a ventilated steel cabinet. Waste pipets and resist soaked wipes are collected for disposal. A list of stocked resists appears on the lithography processing web page. Other chemicals should be OK'd by laboratory staff prior to use in the laboratory.
