Dummy wafers (also known as test wafers) are primarily utilized for experimental and testing purposes, distinguishing them from standard product wafers.
Consequently, reclaimed wafers are predominantly utilized as dummy (test) wafers.

Dummy wafers are frequently used in production setups to enhance safety at the start of the production process and are employed for delivery checks and process evaluation.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors in most applications.

Wafers treated with film deposition are referred to as film wafers.
Examples of films used (film growth) include isolation films serving as inter-layer isolation materials, metal films as conductive materials, and process materials such as resist and protective films.
