Download or read book High Aspect Ratio Polystyrene Structure and Nano gap Electrode Fabrication Using Electron Beam Lithography written by Azizah Azibi and published by . This book was released on 2017 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has experienced a rapid growth over the past decade, thanks to the development of nanofabrication technologies needed to fabricate nano-devices. The key technique for nanofabrication is nano-lithography. Among the various lithography methods, electron beam lithography (EBL) is the most popular one for R&D and prototyping. EBL uses a focused electron beam to expose a polymer material called resist, such that it undergoes chemical reaction to render it soluble (positive resist) or insoluble (negative resist) by developer. One particular challenge for EBL is the fabrication of high aspect ratio (structure height over width or diameter) nano-structures, which often suffers from pattern collapse caused by capillary force during rinsing liquid drying. In this study we report a novel approach to tackle this issue to a certain degree. We form an array of thin “ceiling” on top of the tall resist structures (here an array of pillar) to “hold” them together and thus reduce the structure collapse. Meanwhile, development can still be completed by optimizing the size of the ceiling patches such that developer has enough time to enter and dissolve the unexposed negative resist under the ceiling. The “ceiling” can be formed by low-energy electron beam exposure that will cross-link only the upper portion of the thick resist; whereas the tall resist structure is exposed at high energy having deep penetration depth. Pattern collapse or detachment was greatly reduced by using our technique, though some degree of structure deformation was found after development. Using high aspect ratio resist structures, it is possible to fabricate high aspect ratio functional materials such as silicon.
Download or read book Assembly of Molecular Nanomagnets Into Nanogap Electrodes by Dielectrophoresis Realization of Bioelectronic Devices for Electrical Measurement of Ionic Current Through Membrane Protein Channels written by Yaser Vaheb and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of two parts. The two parts correspond to two different subjects but with a common feature which is the fabrication of nanometer scale devices for low current measurements. The first part investigated the assembly of Prussian blue and Cs-Co-Cr Prussian blue analogue molecular nanomagnets into nano-patterned electrodes. The ever growing need for higher performance processors and higher storage densities has pushed the CMOS technology commonly used in industry to its physical limitations toward its miniaturization. Molecular electronics and molecular spintronics prove to be promising alternatives for the CMOS in future nanoelectronic devices. Pd or Au gaps with ~ 7-50 nm width were fabricated on a Si/SiO2 substrate using standard electron beam lithography, metal deposition and lift-off. Nanomagnets were positioned between the gaps via AC dielectrophoresis (DEP). At room temperature, the Cs-Co-Cr Prussian blue analogue nanoparticles exhibited negligible current whereas junction with Prussian blue nanoparticles exhibited ~ 30 pA at ~ 1 V. Water trapped in nanogaps was found to seriously alter current measurements. This problem was solved by heating samples prior to measurements. A simplified DEP simulation program using Delphi was developed, which neglected Brownian motion and fluid dynamics but allowed us to better understand the DEP process. The second part of the thesis investigated the fabrication of devices for measuring electrical currents through membrane protein channels. Membrane-embedded protein channels are the basis of various physiological processes like nervous communication, muscular contraction, tactile sensation, and so on. Electrical measurements are used in different applications such as drug screening in pharmaceutical industry and biosensors. The standard method to perform such measurements is the use of patch-clamp. However, this method requires intense skill and heavy equipment while it exhibits low measurement efficiency. A solution to these drawbacks is the development of planar patch clamps, which are scalable, automated and easier to use. The first device fabrication step was the patterning of Au/Ag electrodes on thermally oxidized Si substrate by optical lithography, metallization and lift-off. Secondly, a passivation layer of Si3N4/SiO2 was deposited on top of electrodes by PECVD. Then micro-holes were formed inside the Si3N4/SiO2 passivation layer stack using Raith-150 e-beam lithography and reactive ion etching. Finally, Ag layer was converted to AgCl using bleach. The test of electrical current was done using Axopatch patch-clamp amplifier. Current versus time measurements for different voltages were recorded without membrane covering the holes, and an electrical model has been developed for the fabricated devices.

Available in PDF, EPUB and Kindle. Book excerpt: Nanoscale Electrochemistry focuses on challenges and advances in electrochemical nanoscience at solid–liquid interfaces, highlighting the most prominent developments of the last decade. Nanotechnology has had a tremendous effect on the multidisciplinary field of electrochemistry, yielding new fundamental insights that have broadened our understanding of interfacial processes and stimulating new and diverse applications. The book begins with a tutorial chapter to introduce the principles of nanoscale electrochemical systems and emphasize their unique behavior compared with their macro/microscopic counterparts. Building on this, the following three chapters present analytical applications, such as sensing and electrochemical imaging, that are familiar to the traditional electrochemist but whose extension to the nanoscale is nontrivial and reveals new chemical information. The subsequent three chapters present exciting new electrochemical methodologies that are specific to the nanoscale, including "single entity"-based methods and surface-enhanced electrochemical spectroscopy. These techniques, now sufficiently mature for exposition, have paved the way for major developments in our understanding of solid–liquid interfaces and continue to push electrochemical analysis toward atomic-length scales. The final three chapters address the rich overlap between electrochemistry and nanomaterials science, highlighting notable applications in energy conversion and storage. This is an important reference for both academic and industrial researchers who are seeking to learn more about how nanoscale electrochemistry has developed in recent years.
