MOSFET stands for metal oxide semiconductor field effect transistor. This is primarily due to their use in logic circuits, where they perform the binary switching and memory storage operations in computer processors and memory. Over time, they have overtaken all other electronic components, becoming the most widely produced electronic component in history. These attributes make MOSFETs perfect for use in computer applications. In addition, their simple design makes them perfect for scaling down to almost atomic sizes. What makes them unique is that they use an electric field to control current this means that other than a small amount of leakage current, MOSFETs don’t dissipate a significant amount of power in order to function. Like other forms of transistors, MOSFETs can be used as a switch and as an amplifier. Most of this progress came from the scaling and design of MOSFETs. Moore’s Law plot, showing the increase in number of transistors on microchips over time.

These attributes make them perfect for use in integrated circuits like computer processors and memory. As their size decreases, the average cost per transistor also decreases. They can also be scaled to incredibly small sizes (as predicted by Moore’s Law). First, MOSFETs use voltage, rather than current, to control operation so power consumption is extremely low. There are a few advantages of MOSFETs that have enabled them to become so popular. Like many other semiconductor devices, a MOSFET is usually made of doped silicon. An estimated 13 sextillion (13 x 10 21) MOSFETs had been produced by 2020.Ī MOSFET is a semiconductor device that controls the flow of current by using a voltage signal to modulate the width of a conductive channel in the body of the transistor. They form the backbone of the modern computer industry, and their contribution to human civilization would be difficult to overstate.
