Electromigration simulation for metal lines
WebSep 1, 2024 · Electromigration is a phenomenon that metallic atoms constructing the line are transported by electron wind. The damage induced by electromigration appears as the formation of voids and hillocks. WebElectromigration test and simulation have shown that the thermal stress migration has also made the faster void formation at the top metal (junction to the via area) of the via …

WebElectromigration Simulation for a Wafer Level Via Structure. An actual electromigration test for a wafer level via structure is performed. The detailed EM test is arranged as follows: two metal lines consisting of Al (1%Si) with TiN/Ti barrier metals on the topography of silicon oxide SiO 2 ... WebAug 28, 2024 · When we examine the random growth of trees along a linear alley in a rural area, we wonder what governs the location of those trees, and hence the distance between adjacent ones. The same question arises when we observe the growth of metal electro-deposition trees along a linear cathode in a rectangular film of solution. We carry out …
