Effect of Initial Resist Thickness on Residual Layer Thickness of Nanoimprinted Structures

December 1, 2005
Author(s)
Hae-Jeong Lee, Hyun Wook Ro, Christopher L. Soles, Ronald L. Jones, Eric K. Lin, Wen-Li Wu, Daniel R. Hines
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

Acoustic Modes and Elastic Properties of Polymeric Nanostructures

October 21, 2005
Author(s)
R Hartschuh, A Kisliuk, V N. Novikov, Alexei Sokolov, Paul R. Heyliger, Colm Flannery, Ward L. Johnson, Christopher Soles, Wen-Li Wu
Fabricating mechanically robust polymer structures with nanoscale dimensions is critical for a wide range of emerging technologies. The rigidity of such structures is expected to change as the feature sizes approach the characteristic dimensions of the

Characterization of Ordered Mesoporous Silica Films Using Small-Angle Neutron Scattering and X Ray Porosimetry

March 1, 2005
Author(s)
B D. Vogt, R A. Pai, V. J. Lee, R C. Hedden, Christopher L. Soles, Wen-Li Wu, Eric K. Lin, Barry J. Bauer, J J. Watkins
Ordered mesoporous silica films were synthesized using pre-organized block copolymer templates in supercritical carbon dioxide. Poly(ethylene oxide-block-propylene oxide-block-ethylene oxide), PEO-bPPO-b-PEO,films doped with p-toluenesulfonic acid (p-TSA)

X-ray Absorption Spectroscopy to Probe Surface Composition and Surface Deprotection in Photoresist Films

March 1, 2005
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A. Fischer, S Sambasivan, Eric K. Lin, Ronald L. Jones, Christopher Soles, Wen-Li Wu, D M. Goldfarb, M Angelopoulos
We utilize near edge x-ray absorption fine structure spectroscopy (NEXAFS) to provide chemical insight into surface chemical effects in model photo-resist films. First, NEXAFS was used to examine the resist/air interface including surface segregration of a

Water Distribution Within Immersed Polymer Films

February 1, 2005
Author(s)
B D. Vogt, Christopher Soles, Vivek Prabhu, Sushil K. Satija, Eric K. Lin, Wen-Li Wu
The emergence of immersion lithography as a potential alternative for the extension of current lithography tools will require a fundamental understanding of the interactions between the photoresist and the immersion liquid such as water. The water

Water Immersion of Model Photoresists: Interfacial Influences on Water Concentration and Surface Morphology

February 1, 2005
Author(s)
B D. Vogt, D L. Goldfarb, M Angelopoulos, Christopher Soles, C M. Wang, Vivek Prabhu, P M. McGuiggan, Jack F. Douglas, Eric K. Lin, Wen-Li Wu, Sushil K. Satija
Immersion lithography has emerged as an alternative to the 157 nm node and as such understanding of the interactions between the photoresist and immersion fluid (water) has become a pressing issue. The water concentration within the model photoresist films
