  3. 7. 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
