| 摘要 |
An etching method that uses an etch reactant retained within at least a semi-solid media (120, 220, 224, 230). The etch reactant media is applied to selectively etch a surface layer (106, 218, 222). The etch reactant media may be applied to remove metal shorts (222), smearing and eaves resulting from CMP or in failure analysis for uniform removal of a metal layer (218) without damaging the vias, contact, or underlying structures.
