Webb2) Wafers When etching into Silicon using KOH or TMAH, always use prime wafers. If you are doing a shallow etch, single sided polished is fine, but to go through a wafer or remove a large part of a wafer, double sided is needed to do the alignment. The reason why prime wafers are needed is that the ‘history’ of the wafer is critical Webb27 okt. 2024 · Wafers, whose dimensions are gradually increasing and can reach 200 mm (8 inches), are made of very pure material which, during the manufacturing process, must be polished to obtain a very even and smooth surface.

Assuming a Weibull distribution of the fracture forces, the PC slurry sawn wafers exhibit a slightly higher critical fracture force of 3.68 N compared to 3.53 N for the PEG200 wafers, see Fig. 7. This result is in good agreement with the lower roughness of the PC-slurry sawn ...

A slurry is a mixture of denser solids suspended in liquid, usually water. The most common use of slurry is as a means of transporting solids or separating minerals, the liquid being a carrier that is pumped on a device such as a centrifugal pump. The size of solid particles may vary from 1 micrometre up to hundreds of millimetres. The particles may settle below a certain transport velo… http://www.diva-portal.org/smash/get/diva2:1095703/FULLTEXT01.pdf
