Dummy wafers (also known as test wafers) are primarily used for experimentation and testing, distinct from standard product wafers.
Thus, reclaimed wafers are predominantly utilized as dummy wafers (test wafers).

Dummy wafers are frequently employed in production devices to enhance safety at the start of the production process and are utilized for delivery checks and process form evaluations.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors in most scenarios.

Wafers processed with film deposition are referred to as film wafers.
Examples of films used (growth of film) include isolation films as insulating materials between layers, metal films as conductive materials, and process materials such as resist and protective films.
