Book Description
Microcantilevers for Atomic Force Microscope Data Storage describes a research collaboration between IBM Almaden and Stanford University in which a new mass data storage technology was evaluated. This technology is based on the use of heated cantilevers to form submicron indentations on a polycarbonate surface, and piezoresistive cantilevers to read those indentations. Microcantilevers for Atomic Force Microscope Data Storage describes how silicon micromachined cantilevers can be used for high-density topographic data storage on a simple substrate such as polycarbonate. The cantilevers can be made to incorporate resistive heaters (for thermal writing) or piezoresistive deflection sensors (for data readback). The primary audience for Microcantilevers for Atomic Force Microscope Data Storage is industrial and academic workers in the microelectromechanical systems (MEMS) area. It will also be of interest to researchers in the data storage industry who are investigating future storage technologies.

Book Description
Bringing Scanning Probe Microscopy Up to Speed introduces the principles of scanning probe systems with particular emphasis on techniques for increasing speed. The authors include useful information on the characteristics and limitations of current state-of-the-art machines as well as the properties of the systems that will follow in the future. The basic approach is two-fold. First, fast scanning systems for single probes are treated and, second, systems with multiple probes operating in parallel are presented. The key components of the SPM are the mechanical microcantilever with integrated tip and the systems used to measure its deflection. In essence, the entire apparatus is devoted to moving the tip over a surface with a well-controlled force. The mechanical response of the actuator that governs the force is of the utmost importance since it determines the scanning speed. The mechanical response relates directly to the size of the actuator; smaller is faster. Traditional scanning probe microscopes rely on piezoelectric tubes of centimeter size to move the probe. In future scanning probe systems, the large actuators will be replaced with cantilevers where the actuators are integrated on the beam. These will be combined in arrays of multiple cantilevers with MEMS as the key technology for the fabrication process.

Book Description
Scanning Probe Lithography (SPL) describes recent advances in the field of scanning probe lithography, a high resolution patterning technique that uses a sharp tip in close proximity to a sample to pattern nanometer-scale features on the sample. SPL is capable of patterning sub-30nm features with nanometer-scale alignment registration. It is a relatively simple, inexpensive, reliable method for patterning nanometer-scale features on various substrates. It has potential applications for nanometer-scale research, for maskless semiconductor lithography, and for photomask patterning. The authors of this book have been key players in this exciting new field. Calvin Quate has been involved since the beginning in the early 1980s and leads the research time that is regarded as the foremost group in this field. Hyongsok Tom Soh and Kathryn Wilder Guarini have been the members of this group who, in the last few years, have brought about remarkable series of advances in SPM lithography. Some of these advances have been in the control of the tip which has allowed the scanning speed to be increased from mum/second to mm/second. Both non-contact and in-contact writing have been demonstrated as has controlled writing of sub-100 nm lines over large steps on the substrate surface. The engineering of a custom-designed MOSFET built into each microcantilever for individual current control is another notable achievement. Micromachined arrays of probes each with individual control have been demonstrated. One of the most intriguing new aspects is the use of directly-grown carbon nanotubes as robust, high-resolution emitters. In this book the authors concisely and authoritatively describe the historical context, the relevant inventions, and the prospects for eventual manufacturing use of this exciting new technology.

Book Description
The field of materials and process integration for MEMS research has an extensive past as well as a long and promising future. Researchers, academicians and engineers from around the world are increasingly devoting their efforts on the materials and process integration issues and opportunities in MEMS devices. These efforts are crucial to sustain the long-term growth of the MEMS field. The commercial MEMS community is heavily driven by the push for profitable and sustainable products. In the course of establishing high volume and low-cost production processes, the critical importance of materials properties, behaviors, reliability, reproducibility, and predictability, as well as process integration of compatible materials systems become apparent. Although standard IC fabrication steps, particularly lithographic techniques, are leveraged heavily in the creation of MEMS devices, additional customized and novel micromachining techniques are needed to develop sophisticated MEMS structures. One of the most common techniques is bulk micromachining, by which micromechanical structures are created by etching into the bulk of the substrates with either anisotropic etching with strong alk:ali solution or deep reactive-ion etching (DRIB). The second common technique is surface micromachining, by which planar microstructures are created by sequential deposition and etching of thin films on the surface of the substrate, followed by a fmal removal of sacrificial layers to release suspended structures. Other techniques include deep lithography and plating to create metal structures with high aspect ratios (LIGA), micro electrodischarge machining (J.

Book Description
Micromachined Mirrors provides an overview of the performance enhancements that will be realized by miniaturizing scanning mirrors like those used for laser printers and barcode scanners, and the newly enabled applications, including raster-scanning projection video displays and compact, high-speed fiber-optic components. There are a wide variety of methods used to fabricate micromachined mirrors - each with its advantages and disadvantages. There are, however, performance criteria common to mirrors made from any of these fabrication processes. For example, optical resolution is related to the mirror aperture, the mirror flatness, and the scan angle. Micromachined Mirrors provides a framework for the design of micromirrors, and derives equations showing the fundamental limits for micromirror performance. These limits provide the micromirror designer tools with which to determine the acceptable mirror geometries, and to quickly and easily determine the range of possible mirror optical resolution and scan speed.

Book Description
Microfluidics and BioMEMS Applications central idea is on microfluidics, a relatively new research field which finds its niche in biomedical devices, especially on lab-on-a-chip and related products. Being the essential component in providing driving fluidic flows, an example of micropump is chosen to illustrate a complete cycle in development of microfluidic devices which include literature review, designing and modelling, fabrication and testing. A few articles are included to demonstrate the idea of tackling this research problem, and they cover the main development scope discussed earlier as well as other advanced modelling schemes for microfluidics and beyond. Scientists and students working in the areas of MEMS and microfluidics will benefit from this book, which may serve both communities as both a reference monograph and a textbook for courses in numerical simulation, and design and development of microfluidic devices.

Book Description
Optical Microscanners and Microspectrometers using Thermal Bimorph Actuators shows how to design and fabricate optical microsystems using innovative technologies and and original architectures. A barcode scanner, laser projection mirror and a microspectrometer are explained in detail, starting from the system conception, discussing simulations, choice of cleanroom technologies, design, fabrication, device test, packaging all the way to the system assembly. An advanced microscanning device capable of one- and two-dimensional scanning can be integrated in a compact barcode scanning system composed of a laser diode and adapted optics. The original design of the microscanner combines efficiently the miniaturized thermal mechanical actuator and the reflecting mirror, providing a one-dimensional scanning or an unique combination of two movements, depending on the geometry. The simplicity of the device makes it a competitive component. The authors rethink the design of a miniaturized optical device and find a compact solution for a microspectrometer, based on a tunable filter and a single pixel detector. A porous silicon technology combines efficiently the optical filter function with a thermal mechanical actuator on chip. The methodology for design and process calibration are discussed in detail. The device is the core component of an infrared gas spectrometer.

Book Description
The field of "microelectromechanical systems," or "MEMS," has gradually evolved from a "discipline" populated by a small group of researchers to an "enabling technology" supporting a variety of products in such diverse areas as mechanical and inertial sensors, optical projection displays, telecommunications equipment, and biology and medicine. Critical to the success of these products is the ability to design them, and this invariably involves detailed modeling of proposed designs. Over the past twenty years, such modeling has become increasingly sophisticated, with full suites of MEMS-oriented computer-aided-design tools now available worldwide. But there is another equally important side to the design process In my own book, Microsystem figuring out what to build in the first place. Design, I chose to emphasize the modeling aspect of design. The task of figuring out what to build was defined by a vague step called "creative thinking." I used practical product examples to illustrate the many subtle characteristics of successful designs, but I made no attempt to systematize the generation ofdesign proposals or optimized designs. That systemization is called "synthesis," which is the subjectofthis book.

Book Description
The Microsystems Series has as its goal the creation of an outstanding set of textbooks, references, and monographs on subjects that span the broad field of microsystems. Exceptional PhD dissertations provide a good starting point for such a series, because, unlike monographs by more senior authors, which must compete with other professional duties for attention, the dissertation becomes the sole focus of the author until it is completed. Conversion to book form is then a streamlined process, with final editing and book production completed within a few months. Thus we are able to bring important and timely material into book form at a pace which tracks this rapidly developing field. Our first four books in the series were drawn from the more physics-oriented side of the microsystems field, including such diverse subjects as computer-aided design, atomic-force microscopy, and ultrasonic motion detection. Now, with Sangeeta Bhatia's work, we enter the realm of biology. Her use of artifically structured substrates to encourage the liver cells to form orderly assemblies is a fine example of how microfabrication technology can contribute to cell biology and medicine. I am pleased to be able to add this very new and very interesting work to the Microsystems Series. Stephen D. Senturia Cambridge MA Microfabrication in Tissue Engineering and Bioartificial Organs Foreword One of the emerging applications of microsystems technology in biology and medicine is in the field of tissue engineering and artificial organs. In order to function, cells need to receive proper signals from their environment.
