Out of those components, AP is handiest to attain a excessive etch price with smooth etched floor, and most significantly the whole safety of the exposed Al. Sotoaka studied the impact of assorted kinds of additives on the etch fee of silicon and the hydroxylamine is introduced as more practical additive . Swarnalatha et al. and Narasimha et al. systematically investigated the effect of various concentrations of hydroxylamine on all three etching characteristics (i.e. etch fee, etched floor morphology, and undercutting) in TMAH and KOH . In addition, the etch rate of SiO2 and its selectivity with silicon are investigated.
