Dummy wafers (also called as test wafers) are wafers mainly used for experiment and test and being different from general wafers for product.
Accordingly, reclaimed wafers are mostly applied as dummy wafers (test wafers).
Dummy wafers are often used in a production device to improve safety in the beginning of production process and are used for delivery check and evaluation of process form.
As dummy wafers are often used for experiment and test, size and thickness thereof are important factors in most occasions.

Examples of film to be used (growth of film) include isolation film as isolation material between layers, metal film as conductive material, process material such as resist and protective film.
