Effect of BOE etching time on wire bonding quality
The dependence of wire bond-pull strength on the morphology of the underlying polycrystalline silicon (poly-Si) beneath the bondpad metal is studied using atomic force microscopy(AFM). Statistical analysis shows that the roughness of the poly-Si is correlated with the wire bond-pull strength. The co...
