This book is an overview of replication technology for micro- and nanostructures, focusing on the techniques and technology of hot embossing, a scaleable and multi-purpose technology for the manufacture of devices such as BioMEMS and microfluidic devices which are expected to revolutionize a wide range of medical and industrial processes over the coming decade. The hot embossing process for replicating microstructures was developed by the Forschungszentrum Karlsruhe (Karlsruhe Institute of Technology) where the author is head of the Nanoreplication Group. Worgull fills a gap in existing information by fully detailing the technology and techniques of hot embossing. He also covers nanoimprinting, a process related to hot embossing, with examples of actual research topics and new applications in nanoreplication. *A practical and theoretical guide to selecting the materials, machinery and processes involved in microreplication using hot embossing techniques. *Compares different replication processes such as: micro injection molding, micro thermoforming, micro hot embossing, and nanoimprinting *Details commercially available hot embossing machinery and components like tools and mold inserts
This five-volume handbook focuses on processing techniques, characterization methods, and physical properties of thin films (thin layers of insulating, conducting, or semiconductor material). The editor has composed five separate, thematic volumes on thin films of metals, semimetals, glasses, ceramics, alloys, organics, diamonds, graphites, porous materials, noncrystalline solids, supramolecules, polymers, copolymers, biopolymers, composites, blends, activated carbons, intermetallics, chalcogenides, dyes, pigments, nanostructured materials, biomaterials, inorganic/polymer composites, organoceramics, metallocenes, disordered systems, liquid crystals, quasicrystals, and layered structures. Thin films is a field of the utmost importance in today's materials science, electrical engineering and applied solid state physics; with both research and industrial applications in microelectronics, computer manufacturing, and physical devices. Advanced, high-performance computers, high-definition TV, digital camcorders, sensitive broadband imaging systems, flat-panel displays, robotic systems, and medical electronics and diagnostics are but a few examples of miniaturized device technologies that depend the utilization of thin film materials. The Handbook of Thin Films Materials is a comprehensive reference focusing on processing techniques, characterization methods, and physical properties of these thin film materials.

The Eighth International Conference on Miniaturized Systems in Chemistry and Life Science - B5Tas 2004 - is an annual meeting focusing on the research, development and application of miniaturized technologies and methodologies in chemistry and life science. The conference is celebrating its tenth anniversary after the first workshop at the University of Twente, The Netherlands in 1994. This research field is rapidly developing and changing towards a domain where core competence areas such as microfluidics, micro- and nanotechnology, materials science, chemistry, biology, and medicine are melting together to a truly interdisciplinary meeting place. This volume is the second in a two volume set, a valuable reference collection to all working in this field.
This book presents applicable knowledge of technology, equipment and applications, and the core economic issues of micromanufacturing for anyone with a basic understanding of manufacturing, material, or product engineering. It explains micro-engineering issues (design, systems, materials, market and industrial development), technologies, facilities, organization, competitiveness, and innovation with an analysis of future potential. The machining, forming, and joining of miniature / micro-products are all covered in depth, covering: grinding/milling, laser applications, and photo chemical etching; embossing (hot & UV), injection molding and forming (bulk, sheet, hydro, laser); mechanical assembly, laser joining, soldering, and packaging. • Presents case studies, material and design considerations, working principles, process configurations, and information on tools, equipment, parameters and control • Explains the many facets of recently emerging additive / hybrid technologies and systems, incl: photo-electric-forming, liga, surface treatment, and thin film fabrication • Outlines system engineering issues pertaining to handling, metrology, testing, integration & software • Explains widely used micro parts in bio / medical industry, information technology and automotive engineering. • Covers technologies in high demand, such as: micro-mechanical-cutting, lasermachining, micro-forming, micro-EDM, micro-joining, photo-chemical-etching, photo-electro-forming, and micro-packaging

Abstract: This paper reports a highly effective technique for rapid fabrication of microlens arrays based on an ultrasonic assisted hot embossing process. In this method, a thin stainless steel mold with micro-holes array is fabricated by a photolithography and wet etching process. Then, the thin stainless steel mold with micro-holes array is placed on top of a plastic substrate (PMMA plate) and the stack is placed in an ultrasonic vibration embossing machine. During ultrasonic assisted hot embossing operation, the surface of the stainless steel mold with micro-holes array presses against the thermoplastic PMMA substrate. Under proper ultrasonic vibration time, embossing pressure and hold time, the softened polymer will just partially fill the circular holes and due to surface tension, form a convex lens surface. After the stainless steel mold is removed, the microlens array patterns on the surface of plastic substrate can be obtained. The total cycle time is less than 10 s. Finally, geometrical and optical properties of the fabricated plastic microlens arrays were measured and proved satisfactory. This technique shows great potential for fabricating microlens array on plastic substrates with high productivity and low cost.
