CPMI represented at iPlasmaNano II

December 8, 2010

The Second International Symposium on Plasma Nanoscience (iPlasmaNano-II) is being held in Australia from December 12-15 at the Murramarang Eco-Tourisim Resort located in South Durras, New South Wales, Australia.

The Symposium, this year, is organised at an expert-level to map the over all development of this rapidly growing reserach field and to prepare for the first-ever Special “Perspectives” issue of the Journal of Physics D: Applied Physics focused on the achievments, challenges and opportunities for the Plasma Nanosciences in the coming decade. The Symposium has many of the leading scientists and early-career researchers from all over the world participating.

Center for Plasma Materials and Interactions (CPMI) director, Prof. David Ruzic, will be representing the Center at this workshop and will give a presentation on Monday afternoon talking about High Energy Density Plasmas for Nano-fabrication.

Further details of the symposium can be found at http://www.acpo.csiro.au/iPlasmaNano/

You can also follow Prof. Ruzic (@EnergyProf) and the CPMI lab (@illinoisCPMI) at the conference on twitter.

Flux and energy analysis of species in hollow cathode magnetron ionized physical vapor deposition of copper

L. Wu, E. Ko, A. Dulkin, K. J. Park, S. Fields, K. Leeser, L. Meng, and D. N. Ruzic

To meet the stringent requirements of interconnect metallization for sub-32 nm technologies, an unprecedented level of flux and energy control of film forming species has become necessary to further advance ionized physical vapor deposition technology. Such technology development mandates improvements in methods to quantify the metal ion fraction, the gas/metal ion ratio, and the associated ion energies in the total ion flux to the substrate. In this work, a novel method combining planar Langmuir probes, quartz crystal microbalance (QCM), and gridded energy analyzer (GEA) custom instrumentation is developed to estimate the plasma density and temperature as well as to measure the metal ion fraction and ion energy. The measurements were conducted in a Novellus Systems, Inc. Hollow Cathode Magnetron (HCMTM) physical vapor deposition source used for deposition of Cu seed layer for 65–130 nm technology nodes. The gridded energy analyzer was employed to measure ion flux and ion energy, which was compared to the collocated planar Langmuir probe data. The total ion-to-metal neutral ratio was determined by the QCM combined with GEA. The data collection technique and the corresponding analysis are discussed. The effect of concurrent resputtering during the deposition process on film thickness profile is also discussed. © 2010 American Institute of Physics.

CPMI Welcomes New Postdocs: Tae Cho and Daniel Andruczyk

September 15, 2010

CPMI will be welcoming two new postdoctoral researchers on September 16th.  Both are experienced researchers and will be an asset to the CPMI team.

Tae Cho comes to us from Korea. He received his PhD in 2002 and has had 8 years of valued experience post PhD. He  has been a postdoctoral researcher in the past, a Chief Engineer, and spent 5 years working in industry.

Daniel Andruczyk comes to us from Austrailia. He  received his PhD in 2006 and has had 4 years of valued experience post PhD.  He has previously been a postdoctoral researcher in two institutions. 

WELCOME!

goodbye_vijay1

Members of the CPMI gathered to wish departing post-doc Vijay Surla well as he leaves the Urbana campus. Vijay has spent the past two years working with the atmospheric plasma and fusion plasma research at CPMI. He will continue his post-doc research of fusion plasmas at the Princeton Plasma Physics Laboratory along with other alums of the CPMI Michael Jaworski and Travis Gray.
Thank you for your work and good luck, Vijay!
