Dummy wafers (also called as test wafers) are specialized wafers primarily used for experimentation and testing, distinctly different from standard production wafers. They play a crucial role in ensuring quality and reliability.
Accordingly, reclaimed wafers find their primary application as dummy wafers (test wafers), serving an essential purpose in various testing environments.
Dummy wafers are invaluable in production devices, significantly enhancing safety at the onset of the production process. They are also vital for delivery checks and process evaluations, ensuring optimal performance and quality.
As dummy wafers are predominantly used for experiments and testing, their size and thickness are critically important factors in most scenarios, influencing the outcome of the testing processes.
Wafers processed with film deposition are known as film wafers, a specialized category designed to meet diverse application needs.
Examples of film growth include isolation films, which act as insulating materials between layers; metal films, serving as conductive materials; and process materials such as resist and protective films, each playing a vital role in semiconductor manufacturing.
