Junctionless Transistor

Junctionless Transistor

Product imagePessimists are always reporting that the semiconductor industry is on the verge of hitting a wall that will no longer allow scaling after a certain size. Some predict this will occur very soon and it will be time over for ever shrinking dies.

EETimes report that Tyndall National Institute (Cork, Ireland) is developing new ways to increase what we can do with silicon-based CMOS technologies and has now put forward the idea of using a junctionless transistor. This will help with power leakage which is a massive problem from 90nm and lower as well as simplifying the leakage problem at the 10nm level and lower.

Currently CPU’s and GPU’s use millions and now even billions of transistors to ever increase performance inside computers and many have openly wondered how much longer we have until we can no longer pack more transistors in a given die area.

To put things in perspective Hardware Heaven hopes you enjoy the picture of the first ever transistor invented by Bell Labs in 1947. Imagine a billion of those transistors going on and off at a rate of billions of times a second and then scale it down to the same size as your fingernail.
