Microfabrication is the process of fabricating miniature structures of micrometre scales and smaller. Historically, the earliest microfabrication processes were used for integrated circuit fabrication, also known as " semiconductor manufacturing " or "semiconductor device fabrication".
Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication ) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller.
Normally a new semiconductor process has smaller minimum sizes and tighter spacing. In some cases, this allows a simple die shrink of a currently produced chip design to reduce costs, improve performance, [16] and increase transistor density (number of transistors per unit area) without the expense of a new design.
The foundry model is a microelectronics engineering and manufacturing business model consisting of a semiconductor fabrication plant, or foundry, and an integrated circuit design operation, each belonging to separate companies or subsidiaries.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
A parallel line of research seeks to create nanoelectronic devices which could interact with single cells for use in basic biological research. [21] These devices are called nanosensors. Such miniaturization on nanoelectronics towards in vivo proteomic sensing should enable new approaches for health monitoring, surveillance, and defense technology.
A company making accelerometers for airbags would need a completely different design and process to produce an accelerometer for inertial navigation. Changing from an accelerometer to another inertial device such as a gyroscope requires an even greater change in design and process, and most likely a completely different fabrication facility and ...
MEMS microcantilever resonating inside a scanning electron microscope Proposal submitted to DARPA in 1986 first introducing the term "microelectromechanical systems". MEMS (micro-electromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts.
