Which outcome occurs for copper interconnects on a microchip due to increased electron density at atomic defects?

💡 Explanation

Electromigration induced material accumulation occurs because momentum transfer from electrons to metal ions via momentum exchange facilitates atomic diffusion. Therefore, material accumulates downstream at grain boundaries, leading to failure, rather than improving the chip, because of structural degradation.
