Microelectronics materials engineers design, develop and supervise the production of materials that are required for microelectronics and microelectromechanical systems (MEMS), and are able to apply them in these devices, appliances, products. They aid the design of microelectronics with physical and chemical knowledge about metals, semiconductors, ceramics, polymers, and composite materials. They conduct research on material structures, perform analysis, investigate failure mechanisms, and supervise research works.
