Moore’s law has obviously nothing to do with metallurgical science but as I have dedicated this section to the role of metallurgical science in microelectronics, I thought it is worth to go through Moore’s law briefly before anything else as it is the foundation of the current high-tech advancement.
Moore’s law was initially introduced in 1965 by Gordon E. Moore, the co-founder of the Intel Corporation and Fairchild Semiconductor, through which he predicted that the number of transistors on an integrated circuit double every two years. This means faster processing speed and smaller / lighter electronic devices over every few year time period (compare the first portable computer Osborne 1 weighing around 23 pounds and 64 KB of main memory to your smartphone right now in your hand with various functions and a possible capacity of 128 GB storage). In other words, Moore’s prediction is the basis of all amazing advancement in the last 50 years by setting the destination for microelectronic industry. To put this in perspective, imagine applying Moore’s law to automotive industry, then now we would have cars with the capacity of 300000 miles/hour, 2000000 miles/gallon and all for the price of only 4 cents. Moore’s law not only has set the pace at which semiconductor industry develop, but also it has shaped the world we are living in today. It is the foundation of Moore’s law that is driving the way we communicate, work, study and entertain today.
However, concerns are raising in regards to the limits of Moore’s law as we are now literally approaching those limits. The concerns stem from the fact that transistors cannot get smaller than a few nanometres physically and technically and this is where it is argued to be the limits of Moore’s law and consequently end of an era. Though, a review of research literature and industrial trend make it clear that Moore’s prediction is far beyond the number of transistors on an integrated circuit. In more general terms, it is about approaches to increase the computing power and reducing cost and if one approach is reaching its limit, other approaches will be developed. Even the recent trend of “More than Moore” (MtM) is a direct consequence of Moore’s prediction and it is not detachable from Moor’s law by nature. Currently, it appears that microelectronic industry have a high spirit to keep up the pace and I strongly believe that Moore’s law will continue to revolutionize human life with the same speed if not higher in the next decades. Best is yet to come.
