| Term | Definition |
| MEMS pro | A PC based MEMS layout, design and simulation package marketed by MEMSCAP, originally developed by Tanner EDA. |
| Metastability | A flip-flop has two well-defined stable conditions, \'1\' and \'0\'. When there is a violation in setup or hold time of Flip-Flop, it enters into a state called metastable state, where the output of Flip-Flop is unpredictable. This is so called metastability. It is also called quasi stable state. |
| Methodology | The structured series of steps used in the design of microsystems. |
| Micro Tip | A single, field emission Tip used in FED display technology and fast cold cathode vacuum electronics. Derived from the tip used in a scanning –tunneling electron microscope. |
| Micro-System-Technology | A more general statement of MEMS including optical and fluidic systems. MST is a more common term than MEMS in Europe and Japan. |
| Microcircuit | A circuit consisting of a number of transistors built and interconnected on a single semiconductor substrate. |
| Microelectronics | The techniques of designing and fabricating small electronic circuits whose key components measure only billionths of a metre in length. Microelectronics is the “structural steel” that supports electronic and photonic systems. |
| Microfluidics | The study of fluid flow in channels of 100 microns or less in dimension. The use of microfluidics includes applications in biotechnology. |
| Micromachine | Structures and machines with micron feature sizes. These machines can have many functions, including sensing, communication and actuation. |
| Micromirror | Mirrors of very small size and can be fabricated on a chip. Micromirrors are used to steer/scan a light beam at micron scale. |
| Microsystems | Include microelectronics, photonics, optoelectronics, micromachining, microfluidics, embedded software and progressively nano-scale phenomena. |
| MIPI | MIPI The Mobile Industry Processor Interface (MIPI) Alliance is an open membership organization that includes leading companies in the mobile industry that share the objective of defining and promoting open specifications for interfaces in mobile terminals. MIPI has several working groups such as the 1. Camera Working Group 2. Device Descriptor Block Working Group 3. DigRF 4. Display Working Group 5. High-Speed Synchronous Interface Working Group 6. Low-Speed Multipoint Link Working Group 7. NAND Software Working Group 8. Physical Layer Working Group 9. Software Working Group 10. System Power Management Working Group 11. Test & Debug Working Group 12. UniPro Working Group |
| Mixed-signal | A design in which both analog and digital circuits are present on the same chip. |
| Modelling | The capture of the physical and functional behaviour of a technology or component within a computer program that is then used to test its response to various stimuli without requiring actual realization. |
| Module | An interconnected subsystem of a number of microsystem components, usually designed to form a building block for more complex systems. |
| MOS | A type of integrated circuit fabrication fabrication process based on insulated gate field effect transistors originating from the VLSI industry. The process layers from top to bottom are: Metal, insulating oxide, semiconductor. |
| Multi-User MEMS Process | Foundry process & standard developed by Cronos. The process allow several device / system designs to be fabricated simultaneously on one wafer. |
| Nanotechnology | Technology involved with design and fabrication of devices and thin films with dimensions in the nanometer range (1E-9 m). |
| Netlist | A version of an electronic circuit on a CAD system consisting of all of the circuit element names/reference designators, listed with their input and output signal names, in a format similar to . Netlists are the primary form of a circuit used for CAD simulation. |
| nMOS | An n-channel metal-oxide semiconductor transistor is one in which n-type dopants are used in the gate region. A positive voltage on the gate turns the device on. |
| Non-volatile memory | Information stored is maintained after the power supply is turned off. |
| Nyquist Principle | Nyquist principle states that the sampling rate must be at least twice the maximum bandwidth of the analog signal in order to allow the signal to be completely represented. The maximum bandwidth of the signal is called the Nyquist frequency. |
| OLED | A flat panel display technology that requires no backlight and could someday be simpler to construct than LCD screens. |
| Optical Routing | The routing of signals implemented via optical switches as opposed to electrical switches. |
| Optical Switch | A switch that enables signals in optical fibres or integrated optical circuits to be selectively switched from one circuit to another. |
| Optoelectronic Integrated Circuit. | A monolithic integration of several different photonic, optoelectronic, and/or electronic devices on the same chip.. |
| Optoelectronics | A subset of photonics concerned with the application of electronic devices that interact with light, including invisible forms of radiation such as ultraviolet and infrared. |
| Oxide layer | A layer of an integrated circuit created to provide isolation between conductive layers. |
| Parametric test | A test that measures and compares an ASIC part\'s voltages, currents, and timing against specified values. |
| Parasitic transistor leakage | A transistor defect where inadvertent channel inversion causes leakage from drain to source. |
