Dummy wafers (also known as test wafers) are primarily used for experiments and tests, differing from standard production wafers.
Reclaimed wafers are predominantly used 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 used for delivery checks and process evaluations.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors.

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