Beam Processing Technologies


Book Description

Beam Processing Technologies is a collection of papers that deals with the miniaturization of devices that will be faster, consume less power, and cost less per operation or fabrication. One paper discusses metal oxide semiconductor (MOS) integrated circuit technology including the operation of devices whose lateral and vertical dimensions are scaled down. If the devices' silicon doping profiles are increased by the same scale factor, they can operate on lower voltages and currents, with the same performance. Another paper describes laser beam processing and wafer-scale integration as techniques to increase the number of devices on a silicon chip. Electron beam technologies can be used in many fabrication processes such as in microlithography, selective oxidation, doping, metrology. Ion beam applications depend on the presence of the ion introduced into the device (e.g. implantation doping), on pseudoelastic collisions (e.g. physical sputtering or crystal damage), and on inelastic scattering (e.g. polymer resist exposure). Silicon molecular beam epitaxy (SiMBE) can also grow high-quality layers at low temperature, particularly concerning germanium, especially as reagrds the growth system design and utilization of n- and p-type doping. Chemical beam epitaxy (CBE) is another epitaxial growth technique that can surpass MBE and metal organic chemical vapor deposition (MO-CVD). The collection is suitable chemical engineers, industrial physicists, and researchers whose work involve micro-fabrication and development of integrated circuits.

Unit Manufacturing Processes


Book Description

Manufacturing, reduced to its simplest form, involves the sequencing of product forms through a number of different processes. Each individual step, known as an unit manufacturing process, can be viewed as the fundamental building block of a nation's manufacturing capability. A committee of the National Research Council has prepared a report to help define national priorities for research in unit processes. It contains an organizing framework for unit process families, criteria for determining the criticality of a process or manufacturing technology, examples of research opportunities, and a prioritized list of enabling technologies that can lead to the manufacture of products of superior quality at competitive costs. The study was performed under the sponsorship of the National Science Foundation and the Defense Department's Manufacturing Technology Program.







Laser and Ion Beam Modification of Materials


Book Description

Laser and Ion Beam Modification of Materials is a compilation of materials from the proceedings of the symposium U: Material Synthesis and Modification by Ion beams and Laser Beams. This collection discusses the founding of the KANSAI Science City in Japan, and the structures, equipment, and research projects of two institutions are discussed pertaining to eV-MeV ion beams. A description of ion beams as used in materials research and in manufacturing processes, along with trends in ion implantation technology in semiconductors, is discussed. Research into ion beams by China and its industrial uses in non-semiconductor area is noted. For industrial applications, developing technology in terms of high speed, large surface modifications and use of high doses is important. Thus, the development of different ion beam approaches is examined. Industrial applications of ion and laser processing are discussed as cluster beams are used in solid state physics and chemistry. Mention is made on a high power discharge pumped solid state physics (ArF) excimer laser as a potential light source for better material processing. Under ion beam material processing is nanofabrication using focused ion beams, important for research work in mesoscopic systems. Progress in the use of ion-beam mixing using kinetic energy of ion-beams to mingle with pre-deposited surface layers of substrate materials has shown promise. Advanced materials researchers and scientists, as well as academicians in the field of nuclear physics, will find this collection helpful.




Engineering Thin Films and Nanostructures with Ion Beams


Book Description

While ion-beam techniques have been used to create thin films in the semiconductor industry for several decades, these methods have been too costly for other surface treatment applications. However, as manufacturing devices become increasingly smaller, the use of a directed-energy ion beam is finding novel industrial applications that require the custom tailoring of new materials and devices, including magnetic storage devices, photonics, opto-electronics, and molecular transport. Engineering Thin Films and Nanostructures with Ion Beams offers a thorough narrative of the recent advances that make this technology relevant to current and future applications. Featuring internationally recognized researchers, the book compiles their expertise in a multidimensional source that: Highlights the mechanisms and visual evidence of the effects of single-ion impacts on metallic surfaces Considers how ion-beam techniques can help achieve higher disk-drive densities Introduces gas-cluster ion-beam technology and reviews its precedents Explains how ion beams are used to aggregate metals and semiconductors into nanoclusters with nonlinear optical properties Addresses current challenges in building equipment needed to produce nanostructures in an industrial setting Examines the combination of ion-beam techniques, particularly with physical vapor deposition Delineates the fabrication of nanopillars, nanoflowers, and interconnected nanochannels in three dimensions by using atomic shadowing techniques Illustrates the production of nanopores of varying dimensions in polymer films, alloys, and superconductors using ion-beam irradiation Shows how fingerprints can be made more reliable as forensic evidence by recoil-mixing them into the substrate using ion beams From the basics of the ion-beam modification of materials to state-of-the-art applications, Engineering Th
