This etching technique is especially powerful just just before "backend" processing (BEOL), where wafers are Ordinarily very much thinner soon after wafer backgrinding, and very delicate to thermal or mechanical pressure. Etching a skinny layer of even a couple of micrometres will remove microcracks developed during backgrinding leading to here the wafer owning considerably enhanced toughness and flexibility devoid of breaking. Anisotropic wet etching (Orientation dependent etching)[edit]
