NNIN/MRC Workshop
Fabrication of sub-100nm features with imprint lithography covering a full wafer
March 4th-5th, 2008
Microelectronics Research Center at JJ Pickle Campus

Abstract
The International Technology Roadmap for Semiconductors (ITRS) has identified several technologies as candidates for future advanced lithography. One of these techniques is the nano-imprint lithography (NIL). The NIL technique performed at MRC is Step and Flash Imprint Lithography (S-FIL™). S-FIL is based on a low viscosity fluid that fills in the cavities of a mold (a 1:1 high resolution quartz mold with features written with Electron-Beam lithography). After UV cure, the mold features are locked onto the substrate with that polymer and are transferred onto the under-layer by successive etching steps.
S-FIL has proven capabilities of forming various geometries including lines, posts, holes, and 3-dimensional tiered structures. The ability to imprint arbitrary geometries has allowed S-FIL to be applied to a number of applications like for example, in biomedicine, optics, magnetic storage,….
In this two days workshop, an introduction to process steps involved in S-FIL (Photolithography, Etching) will be given with lectures. During the two hands-on sessions, attendees will do lab practice by imprinting on IMPRIO100 from Molecular Imprints Inc. as well as by dry etching for transferring sub-100nm imprint patterns into substrate. We will learn how to transfer holes and pillars from the same template by utilizing two imprint resists (A non-Si non-containing monomer and a Si-containing monomer) following by adequate etching processes.
