This module aims to provide an introduction to the rapidly expanding subject of microengineering. Starting with a discussion of the benefits and market demand for microengineered systems, the module investigates clean room-based lithographic and other methods of microfabrication. Micro manufacturing issues for a range of materials such as silicon, polymers and metals will be discussed along with routes to larger scale manufacture. A range of example devices and applications will be used to illustrate manufacturing parameters.

Indicative content includes:

• Overview and history of microengineering. Example application areas. Advantages and disadvantages of microengineered systems. Current and future markets
• Basic photolithography. Masks, Resist technology, Etching, Exposure sources, resolutions. Emerging technologies, Applications and examples
• Silicon crystallography, mechanical properties of silicon, Etch methods, Etch stops, Examples and applications
• Mechanical properties of thin films. Surface machining processes. Poly-silicon processes, Silicon-on-insulator (SOI) processes. Examples and applications
• Resists and lithography. Electrodeposition processes. Injection moulding. Material properties of polymers, Hot embossing.
• Laser principles. Laser wavelengths and pulse regimes. Beam propagation. Machining techniques. Excimer lasers, Femtosecond laser micromachining.

trothwy

Equivalent to 50%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.

dda

Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.

rhagorol

Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
