Journal ArticleDOI
Aqueous-based photoresist drying using supercritical carbon dioxide to prevent pattern collapse
Dario L. Goldfarb,Juan J. de Pablo,Paul F. Nealey,John P. Simons,Wayne M. Moreau,Marie Angelopoulos +5 more
TL;DR: In this article, a supercritical drying process was developed to eliminate the capillary forces naturally present during normal drying of photoresist materials, where supercritical carbon dioxide (scCO2), organic solvents and surfactants were used to prevent the collapse of high-aspect-ratio structures fabricated from aqueous-based photoresists.
Journal ArticleDOI
Effect of thin-film imaging on line edge roughness transfer to underlayers during etch processes
Dario L. Goldfarb,Arpan P. Mahorowala,Gregg M. Gallatin,Karen Petrillo,Karen Temple,Marie Angelopoulos,Stacy Rasgon,Herbert H. Sawin,Scott D. Allen,Margaret C. Lawson,Ranee W. Kwong +10 more
TL;DR: In this paper, an atomic force microscopy is used to investigate the contribution of the imaging resist sidewall topography to the sidewall roughness of the final etched feature in thin photoresists, ARC and hardmasks.
Journal ArticleDOI
Interfacial effects on moisture absorption in thin polymer films.
Bryan D. Vogt,Christopher L. Soles,Ronald L. Jones,Chia-Ying Wang,Eric K. Lin,Wen-Li Wu,Sushil K. Satija,Dario L. Goldfarb,Marie Angelopoulos +8 more
TL;DR: A simple, zero adjustable parameter model consisting of a fixed water rich layer at the interface and bulk swelling through the remainder of the film was developed and found to reasonably correspond to the measured thickness dependent swelling.
Journal ArticleDOI
Direct measurement of the reaction front in chemically amplified photoresists.
Eric K. Lin,Christopher L. Soles,Dario L. Goldfarb,Brian C. Trinque,Sean D. Burns,Ronald L. Jones,Joseph L. Lenhart,Marie Angelopoulos,C. Grant Willson,Sushil K. Satija,Wen-Li Wu +10 more
TL;DR: This work demonstrates the use of x-ray and neutron reflectometry as a general method to measure the spatial evolution of the reaction-diffusion process with nanometer resolution and shows that the reaction front within the material is broad rather than sharply defined and the compositional profile is altered during development.

Method to improve adhesion of photoresist on silicon substrate for extreme ultraviolet and electron beam lithography
Martin Glodde,Dario L. Goldfarb +1 more
TL;DR: An etch process that includes removing an oxide containing surface layer from a semiconductor surface to be etched by applying a hydrofluoric (HF) based chemistry is described in this article, where the HFR-based chemistry terminates the semiconductors surface with silicon-hydrogen bonds, and applying a vapor priming agent bearing chemical functionality based on the group consisting of alkynes, alcohols and a combination thereof to convert the silane terminated surface to a hydrophobic organic surface.
