March 15, 2017

Author(s):

David Brough, Daniel Wheeler, Surya R. Kalidindi

There is a critical need for customized analytics that take into account the stochastic nature of materials internal structure at multiple length scales in...

Modeling Superconformal Electrodeposition Using an Open Source PDE Solver

Author(s):

Daniel Wheeler, Jonathan E. Guyer

Superconformal electrodeposition enables the void-free filling of high aspect ratio features such as trenches or vias in the Damascene metallization process...

Curvature Enhanced Adsorbate Coverage Mechanism for Bottom-Up Superfilling and Bump Control in Damascene Processing

Author(s):

Thomas P. Moffat, Daniel Wheeler, Soo K. Kim, Daniel Josell

Superconformal electrodeposition is explained by the recently developed curvature enhanced adsorbate coverage (CEAC) mechanism. The model is used to...
