New technology has allowed to establish the size of transistors to 2.5 nanometers

Electronics develops simply by leaps and bounds, and if earlier, for example, the TV had a huge size, but now it is very thin and fragile structure. And all this thanks to the fact that the components are constantly reduced in dimensions and now they are not even the size of micrometers and nanometers. In this article I will talk about the size of transistors to 2.5 nanometers.

Get such a small product succeeded engineers from the Massachusetts Institute of Technology and the University of Colorado. They developed the latest method of micro-machining, which has been successfully used for the production of such small transistors.

But just a few years ago the standard for industrial production was considered a chip 14 nanometers and it would create a more compact device is problematic, but it is now (in 2019), IBM is actively experimenting with transistors 5 nanometers.

Production technology

In order to make such a small device, scientists used a thermal etching at the atomic level (ALE). This uses a doped semiconductor material - gallium indium arsenide, which is treated with hydrogen fluoride thereby creating a metal fluoride layer on the substrate surface.

Thereafter, the workpiece is added to a special compound - dimethylaluminum chloride (DMAC), triggering a chemical reaction, in which process the exchange of ligands.

The ions associated with the atoms in the crystal lattice of the metal fluoride, however, takes place when the cleansing DMAC then removes only the individual atoms to the metal surface. For one such etch removes only 0.2 nanometer material occurs due to this extremely accurate etching at the process repeated.

What eventually happened

Using the above-described technology, engineers were field effect transistors with Fin (FinFET). A large part of them are smaller than 5 nm, and the smallest in size were obtained only 2.5 nanometers.

In addition, the tests showed that the work of the new transistors more efficiently the existing 60 per cent of the currently existing and actively uses transistors.

conclusion

New technologies allow for more compact electronic devices, and all thanks to technologies that allow you to control manufacturing processes at the atomic level, literally. Like this, then vote it Like. Thank you for your attention!
