1. 1. Block copolymer-based hybrid nanomaterials for nanoimprint applications

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Author : Philip Sellin; [2022]
   Keywords : Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

   Abstract : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.

3. 2. Inductively-Coupled Plasma Etching for Nanoimprint Si-masters

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Oskar Boström; [2019]
   Keywords : NIL; Semiconductor; EBL; SEM; ICP-RIE; Fluorine Etching; Physics; Technology and Engineering;

   Abstract : In the last decades, engineers have been pushing semiconductor technology towards fabricating ever smaller devices, and will eventually pass the lower limit of currently commonplace optical lithographic techniques. New techniques have been developed, such as nanoimprint lithography. READ MORE

4. 3. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonas Segervald; [2019]
   Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

   Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. READ MORE

5. 4. Reactive Ion Etching of Silicon using F-based chemistry - Exploring the Limits

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Harald Havir; [2018]
   Keywords : Reactive Ion Etching; Plasma Etching; CHF3; SF6; High Anisotropy; Physics and Astronomy;

   Abstract : Dry Etching is widely used in nanoprocessing as a method of pattern transfer onto a hard substrate, like silicon. Improving the resolution of this etch process is an important step in reducing the feature size in, for instance, computer microchips, or Nanoimprint Lithography stamps. READ MORE

6. 5. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

   University essay from Umeå universitet/Institutionen för fysik

   Author : Thomas Moberg; [2018]
   Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

   Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE
