Abstract

It is very important to distinguish Moore’s law from individual device and geometrical scaling. Moore’s law started from an economic viewpoint by noticing an historical trend in the increase of the number of devices “crammed on a chip” [1] by a factor of 2 every year. The interest for such a trend had an obvious advantage to reduce the cost per function. Moore mentioned the fact that the trend would continue in the future (Figure 9.1). Actually, bipolar transistors were the active devices at that time. Microelectronics was not betting on metal oxide semiconductor field effect transistors (MOSFETs) at all. The rise of MOSFET popularity, tackling bipolar domination, occurred by 1970 [2], with a prediction that progress would slow down by the end of the 1970s! Actually, no geometrical scaling rule was clearly set forth before Dennard et al. published their paper [3] on scaling, thanks to the possibility to self-align source and drain doping by ion implantation.
