Training materials are designed to match the real picture of the device at each process step. Following the actual process of making a device, the instructor uses top-view and cross section drawings to explain how the device is built at each step. He also uses drawings and pictures of each piece of process equipment to explain how a process is performed and what problems can occur within each given process or piece of equipment. Some trainees in the class may have more experience in a process area than the instructor, and they may share specific, valuable knowledge with other employees. Since contamination from process equipment is the biggest cause of yield loss, the instructor also explains to fab workers how a particle at each step can affect the yield and discusses how to minimize contamination.
Animation is a high-tech alternative teaching tool for the visualized process flow class.
Video material can be developed to show how each process is performed in each tool as well as how the process moves from step to step. Although it takes time to develop animation material for a process flow, by seeing a movie each participant can visualize how a device is built. Visualize Trainee Progress. The success of a training program is measured by the progress of the trainees. A good way to monitor this is to have trainees demonstrate the skills they have been taught.
