    Between aluminum oxide and silicon nitride lies a whole host of ceramic materials called Si-AlONs that combine the two. The greater proportion of aluminum oxide, the harder the material. The more silicon nitride included, the tougher the material [34]. In the leapfrog race between work materials and tools, the laurels still go to the tools.

    The etch rate for thermal oxide by concentrated HF solution (49%) is about 1 μm min −1 at the ambient temperature. However, the concentrated HF solution degrades easily with use, whereas buffered HF solution has a small decrease in the etch rate. The etch rate by 1:6 buffered hydrofluoric acid (BHF) solutions is about 0.1 μm min −1 at the ambient temperature.
