Available in PDF, EPUB and Kindle. Book excerpt: Advanced lithography grows up to several fields such as nano-lithography, micro electro-mechanical system (MEMS) and nano-phonics, etc. Nano-lithography reaches to 20 nm size in advanced electron device. Consequently, we have to study and develop true single nanometer size lithography. One of the solutions is to study a fusion of top down and bottom up technologies such as EB drawing and self-assembly with block copolymer. In MEMS and nano-photonics, 3 dimensional structures are needed to achieve some functions in the devices for the applications. Their formation are done by several methods such as colloid lithography, stereo-lithography, dry etching, sputtering, deposition, etc. This book covers a wide area regarding nano-lithography, nano structure and 3-dimensional structure, and introduces readers to the methods, methodology and its applications.

Download or read book Investigation of Electron Beam Nanolithography Processes Mechanisms and Applications written by Mohammad A. Mohammad and published by . This book was released on 2013 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron beam lithography (EBL) is the leading technology for versatile two dimensional patterning at the deep (10-100 nm) nanoscale. In addition to its reputation as an enabling technology for next generation advances in industry, its ease of use, accuracy, and cost has made it the technology of choice for rapid sub-micron prototyping in academia and research institutes worldwide. Advances in EBL processing have enabled sub-10 nm fabrication using a variety of materials under limited conditions. Repeatable processing at the deep nanoscale, particularly for dense nanostructure fabrication, requires a systematic quantitative study of all processing steps and their intricate interdependencies. In addition, developing future nanofabrication strategies with features approaching molecular length scales, requires a thorough examination of the molecular interactions taking place in EBL processing. This research project investigates EBL processing using PMMA and ZEP resists through an in-depth quantitative study and analysis of process windows for dense grating fabrication. The effect of processing parameters from each EBL stage on process windows is thoroughly investigated. Through the study of process windows and contrast curves, EBL processing strategies are developed and high resolution processing limits in PMMA and ZEP resists are explored. Furthermore, the EBL development stage involving resist-solvent interactions is studied using molecular dynamics simulations in Accelrys Materials Studio software package, and analyzed using the Flory-Huggins polymer physics theory. Finally, optimized processing strategies for dense grating fabrication are demonstrated and techniques are employed for the fabrication of record ultra-narrow (8 nm) suspended SiCN cantilever structures and high aspect ratio polymer fabrication using novel SML resist.

Download or read book Process and Device Simulation for MOS VLSI Circuits written by P. Antognetti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: P. Antognetti University of Genova, Italy Director of the NATO ASI The key importance of VLSI circuits is shown by the national efforts in this field taking place in several countries at differ ent levels (government agencies, private industries, defense de partments). As a result of the evolution of IC technology over the past two decades, component complexi ty has increased from one single to over 400,000 transistor functions per chip. Low cost of such single chip systems is only possible by reducing design cost per function and avoiding cost penalties for design errors. Therefore, computer simulation tools, at all levels of the design process, have become an absolute necessity and a cornerstone in the VLSI era, particularly as experimental investigations are very time-consuming, often too expensive and sometimes not at all feasible. As minimum device dimensions shrink, the need to understand the fabrication process in a quanti tati ve way becomes critical. Fine patterns, thin oxide layers, polycristalline silicon interco~ nections, shallow junctions and threshold implants, each become more sensitive to process variations. Each of these technologies changes toward finer structures requires increased understanding of the process physics. In addition, the tighter requirements for process control make it imperative that sensitivities be unde~ stood and that optimation be used to minimize the effect of sta tistical fluctuations.
