Microelectronic Engineering: The Future of Miniaturization and Innovation Microelectronics is a branch of Engineering that deals with the design and manufacture of small electronic components and devices. These components are typically made up of tiny electronic circuits and conductors, hence the name “micro” electronics. Microelectronic Engineering, also known as semiconductor engineering, is a specialized field within microelectronics that focuses on the design, fabrication, and testing of microelectronic components at an incredibly small scale.
