Dummy wafers, also known as test wafers, are primarily utilized for experimental and testing purposes, distinguished from standard product wafers.
As such, reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers are frequently employed in production devices to enhance safety at the onset of the production process and are used for delivery checks and process form evaluations.
Given their frequent use in experimentation and testing, the size and thickness of dummy wafers are critical factors in most situations.

Wafers subjected to film deposition are referred to as film wafers.
Examples of films applied (film growth) include isolation films for layer separation, metal films for conductivity, and process materials such as resist and protective films.
