Dummy wafers (also called test wafers) are primarily used for experimentation and testing, distinct from general product wafers.
Accordingly, reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers are frequently utilized in production devices to enhance safety at the beginning of the production process, and they are essential for delivery checks and process evaluations.
Given their role in experiments and tests, the size and thickness of dummy wafers are critical factors in most scenarios.

Wafers that undergo film deposition are referred to as film wafers.
Examples of films used include isolation films for layer separation, metal films as conductive materials, and process materials such as resist and protective films.
