Consequently, reclaimed wafers are frequently utilized as dummy wafers (test wafers).
Dummy wafers are often employed in production devices to enhance safety at the start of the production process and are used for delivery checks and process evaluations.
Since dummy wafers are commonly used for experimentation and testing, their size and thickness are crucial factors in most instances.
Examples of films utilized (growth of film) include isolation films for layer separation, metal films as conductive materials, and process materials such as resist and protective films.
