silicon the e ect of these pinholes is visible after a 3 - 4 hrs etch in the phosphoric acid/hydroﬂuoric acid mixture described in the previous section. For silicon carbide this is the case already after 1 hr. The e ect of pinholes in these layers is even more pronounced
Isotropic Silicon Etching using HF/Nitric/Acetic Acid (HNA)
This etch is intended as an isotropic wet etch for silicon and polysilicon. Etch rates are on the order of 3-5 µm/min. Silicon nitride is the preferred etch mask for an HNA etch. SiO 2 will be attacked very rapidly by the HF so cannot be used as a mask. DQN
