Novel resist materials for next generation lithography
Fullerene derivatives have been demonstrated as negative-tone resists for electron beam lithography with impressive capability for high resolution and high plasma etching resistance, due to their carbon-rich nature. Their primary drawback of extremely poor sensitivity has been addressed by …

Advances in molecular scale electronics: Synthesis and testing of nanoscale wires and devices
… and tested nanoscale devices that exhibit negative differential resistance with a valley to peak ratio of over 1000:1 that is 10 times that of current solid-state devices and shown long lasting random access memory. The use of these molecular scale wires and devices should allow us to …

Textual Analysis of Management Tone during Conference Calls and the Impact on Capital Markets
This study examines the tone of management disclosures and their impact on capital markets. In particular, I examine the positive and negative tone, as defined by the Harvard IV-4 Dictionary, during conference calls and the impact on analyst accuracy, dispersion of analysts' estimates, cumulative …

Initiated chemical vapor deposition of functional polyacrylic thin films
… patterning of iCVD PGMA thin films with 80 nm negative-tone features achieved. iCVD copolymerization was also investigated to further tune film composition and properties. A surface propagation mechanism was proposed based on the study of the monomer reactivity ratios and the copolymer …

Macroeconomic Forecasting and Market Analysis with Newspaper Articles
… sentiment measures that quantify the positive or negative tone of news articles and shows that such measures can predict macroeconomic activity. A second strand uses topic indicators, capturing variation in the intensity with which different themes are covered in the media. A third, more recent …

Superconducting nanowire single-photon detectors and sub-10-nm lithography
… performance of hydrogen silsesquioxane (HSQ) negative-tone resist. The contrast of HSQ was improved by adding NaCl salt to an aqueous NaOH developer solution. With this improvement, we achieved a high-resolution electron-beam lithography process capable of patterning structures at 9-nm-pitch …

Development of Molecular Glasses for Solvent-Free Photolithography utilizing Combinatorial Vapor Deposition
… the thesis, two types of low molecular weight, negative tone photoresists were investigated: 1.) Research was carried out on molecular glass photoresists which consist of several components. One of these components, a photoacid generator (PAG), generates acid molecules when exposed to suitable …

Materials for next-generation lithography: Crosslinked molecular resists and photo-patternable underlayers
… new techniques. This thesis will explore both negative and positive-tone crosslinked molecular resists as materials capable of sub-50nm imaging. Block copolymers have also emerged as a means of extending the usefulness of current lithographic processes. The last portion of this thesis will …

FABRICATION AND THERMAL ANALYSIS OF POLYIMIDE-BASED X-RAY MASKS AT THE SYNCHROTRON LABORATORY FOR MICRO AND NANO DEVICES, CANADIAN LIGHT SOURCE
… On the plating base, 100 μm of UV-sensitive negative-tone resist Futurrex NR26-25000P® were spin-coated and patterned by UV-lithography. The patterned photoresist served as a template, filling the voids with 80 μm nickel by electrodeposition. These metal structures served as the mask …
