Dummy wafers (also known as test wafers) are primarily used for experimental and testing purposes, differing from conventional production wafers.
Consequently, reclaimed wafers are predominantly utilized as dummy wafers (test wafers).

Dummy wafers are frequently employed in production devices to enhance safety at the initial production stages and are used for delivery checks and process evaluations.
Because dummy wafers are frequently used for experiments and tests, their size and thickness are crucial factors in many applications.

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