PAM-XIAMEN Offers  Dummy Wafer / Test Wafer / Monitor Wafer

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.

In each process, film thickness, pressure resistance, reflection index and presence of pinball are measured using

dummy wafers (test wafers). Also, dummy wafers (test wafers) are used for measurement of pattern size, check

of defect and so on in lithography.

Monitor wafers are the wafers to be used in the case that an adjustment is required in each production step

prior to the actual IC production. For example, when the conditions of each process are set, such as the case of

measuring tolerance of device against ( the variation of ) substrate thickness, monitor wafers are being used as

a substitution of high-standard and high value wafers. Moreover, they are also used for the monitoring purpose in

the process together with product wafers. Monitor wafers are necessary wafer materials as important as product

prime wafers. They are also called as test wafers together with dummy wafers.
