← ScienceWhich outcome results when surface corrosion increases the rate of aluminum oxide formation around microelectronic bond pads?
A)Reduced interface electrical conductivity✓
B)Increased bond wire tensile strength
C)Enhanced thermal dissipation capacity
D)Improved corrosion resistance long-term
💡 Explanation
Increased oxide formation results in reduced conductivity because electron transport is hindered by the electrically insulating aluminum oxide layer via passivation; therefore, conductivity drops, rather than increases or any change to mechanical properties, which is unrelated.
