Abstract

Electromigration phenomenon might be employed in creation of patterns on metallic thin films in the micro range or even in the nano range dimensions 1, 2. This paper puts forward a non- conventional form of mass transfer that has been observed in Chromium thin films under the effect of high current densities when an alternating field is applied. As it has been observed, the high density current, along with the accompanying heat generation, fuels a reaction in which the metal reacts with the ambient air and produces a fluidic compound in a ring-like manner from the electrode. Within the domain of this paper, ramp wave alternating electric field is used with the frequency ranging from 350 Hz to 700 Hz with a stepping of 50 Hz. The velocity of flow, as well as the electrical current are measured with respect to time throughout the duration of the experiment. Added to that several interesting observations were also made. The work reported in this paper will aid in apprehending the flow behavior, helping to get a better grip over the electromigration assisted nanolithography process. © 2020 IEEE.
