Laser-Based Fabrication of Microstructures on Nickel Thin Films and Its Applications in On-Chip Thin Film Inductors
Srikanth Itapu, Vamsi Borra, Daniel G. Georgiev
This work reports on the fabrication of microbump structures on Ni films by single-pulse, localized laser irradiation. Conditions for the reproducible formation of such microstruct…
Metal whisker growth induced by localized, high-intensity DC electric fields
Vamsi Borra, Osama Oudat, Daniel G. Georgiev +2
In this work, a very high, locally applied electric field was used to induce whisker nucleation on an Sn film. The field was generated by using a conductive AFM tip and applying a…
Sn whisker growth mitigation by using NiO sublayers
Vamsi Borra, Srikanth Itapu, Daniel G. Georgiev
The potential of NiO sublayers for whisker growth mitigation has been examined. A thin NiO film was applied on a Cu-coated substrate before the deposition of a thicker Sn layer. Th…
Fabrication of optically smooth Sn thin films
Vamsi Borra, Daniel G. Georgiev, Corey R. Grice
The fabrication of optically smooth thin Sn films by vacuum or electrodeposition techniques is usually challenging. Little has been published on how to address this challenge mainl…
Cultivating Metal Whiskers by Surface Plasmon Polariton Excitation
Vamsi Borra, Daniel G. Georgiev, Victor G. Karpov
This work presents a preliminary experimental study on the possibility to initiate growth of whiskers on the surfaces of some technologically important metals utilizing the enhance…
Modification of Tin (Sn) Metal Surfaces by Surface Plasmon Polariton Excitation
Vamsi Borra, Srikanth Itapu, Victor G. Karpov +1
We report on the modification of tin (Sn) film surfaces under a laser beam irradiation that triggers surface plasmon polariton (SPP) excitations. The observed surface features in t…
