The spray coater at Danchip is located in Cleanroom C-1. The machine is an ExactaCoat from Sono-tek which can be fitted with one of three different nozzles depending on the nature of the spray coating tasks at hand. The three different nozzles (Impact, AccuMist and Vortex) are optimized for different applications such as spray coating of large areas (e.g. entire wafers), smaller areas (e.g. wafer pieces or other small samples) or already structured samples that cannot be coated uniformly by spin coating. All nozzles use an ultrasonic tranducer for atomizing the solution to be spray coated. It is therefore a prerequisite that all components are compatible with this process. This is the case with most substances, although process parameters may need optimization to give satisfactory results. | The spray coater at Danchip is located in Cleanroom C-1.
