Dummy wafers-also known as test wafers-serve a crucial role in experimentation and testing. These specialized wafers differ from typical production wafers, providing an essential component for controlled environments to optimize processes.
Reclaimed wafers typically find their primary application as dummy wafers (or test wafers). Their reutilization maximizes efficiency, making them indispensable in various testing scenarios.
Incorporated in production devices, dummy wafers enhance safety protocols at the inception of production, while also being instrumental in delivery checks and process evaluations, ensuring stringent assessments at each phase.
Given their frequent use in experimental and testing contexts, the size and thickness of dummy wafers are pivotal considerations. These specifications play a crucial role in achieving optimal results across varied applications.
Wafers that undergo film deposition processes are classified as film wafers. This transformation endows them with distinct properties, tailored for advanced functional applications.
Film wafers can be coated with various materials, such as isolation films for layer separation, metal films for conductivity, and process materials like resist and protective films. Each serves a specialized function, enhancing the wafer's application potential.
