This study investigated molecular beam epitaxy (MBE) regrowth through shadow masks developed from AlGaAs/GaAs layers on GaAs 001 substrates. Adjusting the directions of the molecular beams relative to the masks results in in situ lateral structuring. This enabled the authors to modify doping and composition within one layer, to shift it laterally, and even to split it or to reduce its width relative to the mask's aperture. The resolution of this selective area epitaxy (SAE) technique is restricted by half shadows and surface diffusion. With diaphragms and thin masks it is possible to decrease half shadows to a few nanometers. However, diffusion mainly is a material parameter. The authors investigated III-V and II-VI semiconductors. The latter case was extremely dependent on crystal orientation. Along 1-10 diffusion lengths are very short. This is in agreement with ab initio calculations in their group. Thus, lateral structuring with a resolution of a few nanometers is achieved. The authors discuss the degrees of freedom, which arise from different chamber geometries and mask concepts. With simple striped masks complex structures such as stacked three-color detectors or selective contacts to embedded 2DEGs can be realized. Three novel mask concepts are presented. Deeply underetched masks serve as elastic substrates for misfit layers over the critical thickness without plastic relaxation. As an analogy to cleaved edge overgrowth, the authors use masks developed from AlGaAs/GaAs superlattices. Finally interconnected structures with lateral periodicity of a few micrometers have been realized with grid masks. (8 figures, 16 refs.).

Many of the devices and systems used in modern industry are becoming progressively smaller and have reached the nanoscale domain. Nanofabrication aims at building nanoscale structures, which can act as components, devices, or systems, in large quantities at potentially low cost. Nanofabrication is vital to all nanotechnology fields, especially for the realization of nanotechnology that involves the traditional areas across engineering and science. This is the first book solely dedicated to the manufacturing technology in nanoscale structures, devices, and systems and is designed to satisfy the growing demands of researchers, professionals, and graduate students.Both conventional and non-conventional fabrication technologies are introduced with emphasis on multidisciplinary principles, methodologies, and practical applications. While conventional technologies consider the emerging techniques developed for next generation lithography, non-conventional techniques include scanning probe microscopy lithography, self-assembly, and imprint lithography, as well as techniques specifically developed for making carbon tubes and molecular circuits and devices.

Nano and Micro Engineered Membrane Technology is about Nano and micro engineered membrane technology, an emerging new technological area in membrane technology. Potential applications cover a broad spectrum of science, such as micro and nano filtration, gas separation, optics and nanophotonics, catalysis, microbiology, controlled drug delivery, nanopatterning, micro contact printing, atomisation, cross flow emulsification, etc. A brief overview of filtration membranes and pore structures is presented in chapter 1 and in the subsequent chapter 2 an overview is presented of conventional micro perforation methods, like laser drilling, electroforming, precision etching etc. With micro engineering techniques (chapter 3), originating from the semiconductor industry, it is relatively easy to downscale and form submicron pores (down to 100 nm) using photolithographic methods, with e.g. contact masks and wafer steppers. In chapter 4 some elementary fluid mechanics related to fluid flow in conducts and single and multiple orifices is presented covering analytical methods as well as computational fluid dynamics. Much effort has been put in strength and maximum pressure load analysis (chapter 5) of perforated and unperforated membranes. New analytical expressions were obtained that were verified by a number of computer simulations and many experiments. A separate chapter (chapter 6) has been devoted to the pioneering work of manufacturing polymeric perforated membranes because of its potential future economical impact. Large scale microfiltration applications on e.g. skim milk and lager beer are presented in chapter 7, whereas in chapter 8 a micro scale Lab-on-a-Chip microfiltration/fractionation demonstrator is discussed. Nanotechnology and nano engineered membranes is the fascinating topic of chapter 9, with typical examples as nanopatterning, nanophotonics and nanomembrane technology. This book closes with novel pioneering applications on atomization (chapter 10) for deep pulmonary inhale and cross flow emulsification (chapter 11) for the manufacturing of e.g. functional foods and nano/micro emulsions. Overview on the implementation of nano and micro engineering techniques in membrane science; which is an upcoming new cross-road technology Demonstration of feasibility with respect to micro and nano filtration, gas separation, photonic structures, catalysis, microbiology, controlled drug delivery, nanopatterning, micro contact printing, atomisation and emulsification techniques Informative introductions with rules of thumb for fluid flow in micro channels, pressure strength of thin supported perforated and unperforated membranes, silicon micro machining techniques, membrane filtration technology, Rayleigh breakup and cross-flow emulsification

Techniques such as surface patterning have facilitated the emergence of advanced polymers with applications in areas such as microelectronics. Surface patterning of polymers has conventionally been undertaken by optical lithography. However, a new generation of nanolithographic and patterning techniques has made it possible to develop complex patterns at the nanoscale. Non-conventional lithography and patterning summarises this new range of techniques and their industrial applications.A number of chapters look at ways of forming and modifying surfaces for patterning. These are complemented by chapters on particular patterning techniques such as soft lithography, ion beam patterning, the use of nanostencils, photolithography and inkjet printing. The book also discusses prototyping and the manufacture of particular devices.With its distinguished international team of contributors, Non-conventional lithography and patterning is a standard reference for both those researching and using advanced polymers in such areas as microelectronics and biomedical devices. Looks at alternative approaches used to develop complex patterns at the nanoscale Concentrates on state of the art nanolithographic methods Written by a distinguished international team of contributors

The book focuses on various "substrate independent, large throughput" technologies: techniques that are able to build electronics on cheap, low cost, flexible and temperature sensitive substrates, like PEN or other plastic foils, and using inexpensive and large throughput methods like printing. Most of these technologies, in fact, have the potential to enable the revolutionary applications that will be discussed in the book. The book therefore goes beyond "organic" technologies, i.e. technologies that use functional organic materials (namely semiconductors), to explore a broader and even more interesting area of research. The book presents a comprehensive landscape of the new applications enabled by substrate independent, high throughput electronic technologies and their business potential. It explains the link between innovation in technology and in products. It also provides the reader with a clear understanding of the technology and the research challenges in the field. The book is divided in two parts. The first is devoted to applications where the most important selling point is large area. To this domain belong roll-up, flexible and emissive displays based on organic devices (used in backplanes or as display medium), unobtrusive electronics enabling ambient intelligence applications, and the increasingly important photovoltaic applications. The second part is devoted to applications where cost reduction is the main factor. RFIDs, smart labels, organic sensors and printed sensor system belong to this domain. A chapter is devoted to each different application. Each chapter is originally developed for the book by (a group of) world-wide recognized experts in the specific field of application.
