System and final test are performed on Cymer's lasers prior to shipping. The finished laser weighs about 1.2 tons and looks like a big refrigerator. All modules are manually installed by highly trained technicians onto the laser frame inside a class 1000 clean room. The process usually takes one to two days provided that all parts and modules are available. Most of the core module production processes are manual and involve long cycle-times.
Some modules require extensive laser testing prior to installation in the final assembly.
The model encompasses the process from the ordering of material to final shipment. If material is not available, a certain amount of delay time will be generated based on a triangular time distribution. The model was used to generate requirements for resources and equipment. This helped manufacturing in designing the layout of the factory. Cymer conducted analysis of several scenarios with different demand, shift, and parts availability.
