11. Environment-Controlled Spin Coating to Orient Microdomains in Thin Block Copolymer Films
Published: 3/20/2007
Authors: Sangcheol Kim, R M Briber, Alamgir Karim, Ronald Leland Jones, H C Kim
Abstract: We demonstrate a simple and fast methodology to control the orientation of cylindrical microdomains in thin block copolymer films using environment-controlled spin coating. During spinning, the preferential affinity of vapor atmosphere successfully d ...

12. Field-Induced Formation of Linear, Mesoscopic Polymer Chains From Ferromagnetic Nanoparticles
Published: 2/2/2007
Authors: Jason Benkoski, Steven Bowles, Bryan Korth, Ronald Leland Jones, Jack F Douglas, Alamgir Karim, Jeffrey Pyun
Abstract: Polymer-coated ferromagnetic colloids are first assembled with an applied magnetic field and then permanently fixed into one-dimensional mesostructures using a novel liquid-liquid interfacial system known as Fossilized Liquid Assembly. Using polysty ...

13. Line Edge Roughness Characterization of Sub-50nm Structures Using CD-SAXS: Round-Robin Benchmark Results
Published: 1/1/2007
Authors: Chengqing C. Wang, J C Roberts, Robert Bristol, B Bunday, Ronald Leland Jones, Eric K Lin, Wen-Li Wu, John S Villarrubia, Kwang-Woo Choi, James S Clarke, Bryan J Rice, Michael Leeson
Abstract: he need to characterize line edge and line width roughness in patterns with sub-50 nm critical dimension challenges existing platforms based on electron microscopy and optical scatterometry. The development of x-ray based metrology platforms provide ...

14. Photocurable Oil/Water Interfaces as a Universal Platform for 2-D Self-Assembly
Published: 12/14/2006
Authors: Jason Benkoski, Ronald Leland Jones, Jack F Douglas, Alamgir Karim
Abstract: We present a novel platform for the creation of 2-D assemblies from nanoscale building blocks. The system consists of an oil/water interface in which the oil phase can be flash-cured upon UV exposure. The photopolymerizable material, 1,12-dodecaned ...

15. Evidence for Internal Stresses Induced by Nanoimprint Lithography
Published: 11/30/2006
Authors: Hyun Wook Ro, Yifu Ding, Hae-Jeong Lee, Daniel R. Hines, Ronald Leland Jones, Eric K Lin, Alamgir Karim, Wen-Li Wu, Christopher Soles
Abstract: The thermal embossing form of nanoimprint lithography is used to pattern arrays of nanostructures into several different polymer films. The shape of the imprinted patterns is characterized with nm precision using both X-ray scattering and reflectivi ...

16. Advanced Metrology Needs for Nanoelectronics Lithography
Published: 10/1/2006
Authors: Stephen Knight, Ronald Dixon, Ronald Leland Jones, Eric Lin, Ndubuisi G Orji, Richard M Silver, Andras Vladar, Wen-li Wu
Abstract: The semiconductor industry has exploited productivity improvements through aggressive feature size reduction for over four decades. While enormous effort has been expended in developing the optical lithography tools to print ever finer features, sign ...

17. Real Time Shape Evolution of Nanoimprinted Polymer Structures During Thermal Annealing
Published: 7/18/2006
Authors: Ronald Leland Jones, T Hu, Christopher Soles, Eric K Lin, R M Reano, Stella W Pang, D M Casa
Abstract: The real time shape of nanoimprinted polymer patterns are measured as a function of annealing temperature and time using a new metrology technique, Critical Dimension Small Angle X-ray Scattering (CD-SAXS). Periodicity, linewidth, line height, and s ...

18. Effect of Initial Resist Thickness on Residual Layer Thickness of Nanoimprinted Structures
Published: 12/1/2005
Authors: Hae-Jeong Lee, Hyun Wook Ro, Christopher Soles, Ronald Leland Jones, Eric K Lin, Wen-Li Wu, Daniel R. Hines
Abstract: Accurate quantification and control of the residual layer thickness is a critical challenge to achieving sub-50 nm patterning with nanoimprint lithography. While characterization to within a few nanometers is essential, there is currently a lack of ...

19. Nanoimprint Pattern Transfer Quality from Specular X-Ray Reflectivity
Published: 12/1/2005
Authors: V. J. Lee, Christopher Soles, Hyun Wook Ro, Daniel R. Hines, Ronald Leland Jones, Eric K Lin, Wen-Li Wu

20. Rheopexy of Synovial Fluid and Protein Aggregation
Published: 9/5/2005
Authors: Katherine Oates, Wendy Krause, Ronald Leland Jones, R H Colby
Abstract: Bovine synovial fluid and albumin solutions of similar concentration are rheopectic (stress increases with time in steady shear). This unusual flow characteristic is caused by protein aggrega- tion, and the total stress is enhanced by entanglement of ...
