Dummy wafers, also known as test wafers, are primarily utilized for experimental and testing purposes, differing from general production wafers.
Reclaimed wafers are frequently employed as dummy wafers (test wafers) due to their suitability for such applications.

In the production process, dummy wafers are often used initially to enhance safety, perform delivery checks, and evaluate process forms.
Given their frequent use 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 in deposition include isolation films for layer separation, metal films for conductivity, and process materials such as resists and protective films.
