Dummy wafers (also called test wafers) serve as essential tools for experimentation, differing distinctly from standard product wafers.
Accordingly, reclaimed wafers are predominantly utilized as dummy wafers (test wafers), showcasing their versatility.
Dummy wafers play a crucial role in production devices to enhance safety at the onset of manufacturing processes, while also aiding in delivery checks and process evaluations.
As tools vital for experimentation and testing, the size and thickness of dummy wafers are critical considerations in most scenarios.
Wafers processed with film deposition are referred to as film wafers, embodying technological sophistication.
Examples of film to be used (growth of film) encompass isolation films for layer separation, metal films for conductivity, and process materials such as resist and protective films.
