#402 Microtechnology, nanotechnology... quantum technology

Some of us are not only experiencing current era of nanotechnology (1 nm = 10-9 m) from its onset, but also remember times when microtechnology (1 µm = 10-6 m) was a buzz-term in science and engineering.


If the size related trends in technology evolution were to continue, then picotechnology (1 picometer or pm = 10-12 m) should be their continuation. Let's keep in mind, however,  that the average atom is sized at some 20000 picometers. Thus, the very concept of matter manipulation at the picometer level is beyond the realm of the current understanding of how the world around us works. So, picotechnology understood as a size-based continuation of nanotechnology is not going to happen, at least not in the foreseeable future.


Instead, we are in the process of parting ways with geometrical associations and start using nature of atomic-level physical phenomena related to quantum confinement as a reference. When the size of the piece of the solid is reduced to some 10 nm or below, laws of classical physics (with which we are so comfortable!) are no longer adequately describing properties of this solid and quantum physics (which is escaping our  imagination and intuition) is taking over. At this point the term nanotechnology is no longer adequately describing technological status quo and the term quantum technology is becoming a buzz-term in science and engineering.

Posted by Jerzy Ruzyllo at 05:05 PM | Semiconductors | Link is a personal blog of Jerzy Ruzyllo. He is Distinguished Professor Emeritus in the Department of Electrical Engineering at Penn State University. With over forty years' experience in academic research and teaching in semiconductor engineering he has a unique perspective on the developments in this technical domain and enjoys blogging about it.

This book gives a complete account of semiconductor engineering covering semiconductor properties, semiconductor materials, semiconductor devices and their uses, process technology, fabrication processes, and semiconductor materials and process characterization.

With over 2000 terms defined and explained, Semiconductor Glossary is the most complete reference in the field of semiconductors on the market today.
