Slide 5: 5 . Introduction, Continued Slide 6: MST - Microsystems Technology . MEMS - Microelectromechanical System. Manmade devices created using compatible microfabrication techniques that are capable of Converting physical stimuli, events and parameters to electrical, mechanical & optical signals Performing actuation, sensing and other functions 6 Definition and Terms Slide 7: 7 Slide 8: 8 . Electromechanical Systems Functional Block Diagram Slide 9: Materials Crystallography – Forms of Silicon Amorphous Polycrystalline Crystalline “Miller Planes” 9 MEMS Microstructure Fabrication Slide 10: Pattern definition Photolithography Deposition Oxidation, chemical-vapor deposition, ion implantation Removal Etching, evaporation 10 Microstructure Fabrication, Continued Slide 11: 11 MEMS Advantages The advantages of MEMS devices include Size High sensitivity Low noise Reduced cost The applications for MEMS are so far reaching that a multi-billion dollar market is forecast. Key industry applications include transportation, telecommunications and healthcare. Slide 12: Accelerometers Micro Optical Electro Mechanical Systems (MOEMS) Digital Mirror Devices (DMD) used in Projection Devices Deformable mirrors Optical Switches Inkjet Print heads (Microfluidics) Pressure Sensors Seismic Activities - Thermal transfer 12 Current Applications Slide 13: Micro-arrayed biosensors Virus detection Neuron probes (nerve damage/repair) Retina/Cochlear Implants Micro Needles ChemLab Micro Fluidic Pumps Insulin Pump (drug delivery) 13 Biomedical Current Applications, Continued Slide 14: Hand held detectors – biological & chemical microsensors Chem’s Lab on a Chip (security applications) Data Storage Systems IBM Millipede storage system – AFM tip writes data bit by melting a depression into polymer mediaum and reads data by sensing depressions. 14 Detection systems Current Applications, Continued Slide 15: Nanotechnology manipulation of matter at the nanometer scale. Nanomaterials Started with carbon. Behavior depends on morphology. 15 carbon and carbon nanotube NEMS and Nanotechnology Slide 16: Quantum dots Nanowires Quantum films 16 Quantum Dots. NEMS and Nanotechnology, Continued Slide 17: 17 Electrostatic manipulation Moving one electron or molecule at a time Patterning Dip Pen Lithography Electron Beam Lithography Nano Fabrication NEMS and Nanotechnology, Continued Slide 18: 18 Cantilever Sensors Mass Storage (IBM) Millipede chip Nanochip Molecular Electronics Transistors Memory cells Nanowires Nanoswitches Merging of technologies Slide 19: 19 Cantilever sensors are essentially MEMS cantilevers with chemical arrays attached. The cantilevers, acting much like tuning forks, have a natural frequency of vibration which changes as more mass is attached (nano function). The change in frequency is sensed by the MEMS device indicating a measurable presence in the system of particular reacting compound. Cantilever sensor Merging of technologies NEMS and Nanotechnology, Continued Slide 20: Potential Positive Impacts Reduction of disease. Job opportunities in new fields. Low-cost energy. Cost reductions with improved efficiencies. Improved product and building materials. Transportation improvements Potential Negative Impacts Material toxicity Non-biodegradable materials. Unanticipated consequences. Job losses due to increased manufacturing efficiencies. 20 Impact of Miniaturization Slide 21: Fundamental and applied research Engineering and technological developments Low Cost Fabrication “Molecular manufacturing” 21 Challenges and Possibilities References : References Gad-el-Hak, M.
