Silicon nanowire AFM tips grown on released scanning probe cantilevers from stencil-deposited catalysts

We present a parallel, full wafer technique for deposition of catalyst on released scanning probe bodies for the growth of individual high aspect-ratio Si nanowire tips. 1-D probes are necessary for imaging high aspect-ratio nano-patterns, such as deep and ...

Phototocatalytic Lithography of Poly(propylene sulfide) Block Copolymers: Toward High-Throughput Nanolithography for Biomolecular Arraying Applications

Jeffrey Alan Hubbell

Photocatalytic lithography (PCL) is an inexpensive, fast, and robust method of oxidizing surface chemical moieties to produce patterned substrates. This technique has utility in basic biological research as well as various biochip applications. We report o ...

Development of novel SU-8 based nanoimprint lithography

Shenqi Xie, Rong Yang

We present two kinds of novel nanoimprint lithography techniques based on SU-8 photoresist with single layer and tri-layer approaches. The imprint templates with high aspect ratio were first fabricated by electron beam lithography (EBL) and reactive ion et ...

Nanobiosensors based on individual olfactory receptors

Luis Guillermo Villanueva Torrijo

The animal olfactory system represents the gold standard of biosensors, due to its ability to identify and discriminate thousands of odorant compounds with very low thresholds. Using olfactory receptors (ORs) as sensing elements instead of chemical sensors ...

3-D modulable PDMS-based microlens system

Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto

The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...

STAMP FABRICATION FOR NANOIMPRINT LITHOGRAPHY BY PATTERN DEFINITION WITH STENCIL LITHOGRAPHY

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Nao Takano

A silicon stamp for nanoimprint lithography (NIL) was fabricated from the patterns defined by stencil lithography. Since stencil lithography has a capability of producing sub-micron patterns in a single process, we were able to make a silicon stamp with a ...

Nanostencil Lithography - Quick & Clean: Towards a reliable scalable nanopatterning method

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena, Nao Takano

Stencil lithography is a surface patterning technique that relies on the local deposition of material through miniaturized shadow mask membranes. This method has been used since many years in various implementations for the formation of patterns, mainly st ...

Topography Mediated Patterning of Inorganic Materials by Spray Pyrolysis

Nico de Rooij, Danick Briand

A simple technique for microstructuring ceramic thin films by micromachining substrates using standard photolithographic techniques was investigated. The ceramic perovskite is used to illustrate the method because of its importance for the fabrication of e ...

Advancing towards well-controlled full-wafer nanostencil lithography

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Nao Takano

The endeavour to develop nanodevices demands for patterning methods in the nanoscale. To bring nanodevices to the market, there is a need for fast, low-cost replication nanopatterning methods. In addition, an increased flexibility of the nanopatterning met ...
