Dummy wafers, also known as test wafers, are primarily utilized for experiments and testing, distinguished from general product wafers by their specific application.
Accordingly, reclaimed wafers are predominantly used as dummy wafers (test wafers) in various applications.

In production devices, dummy wafers are frequently used to enhance safety at the start of the production process and are essential for delivery checks and process evaluations.
Given their use in experiments and tests, the size and thickness of dummy wafers are crucial factors in most scenarios.

Wafers that undergo film deposition are termed film wafers.
Examples of films used (growth of film) include isolation films for layer separation, metal films as conductive materials, and process materials like resist and protective films.
