For 50 years, Moores Law has reliably described exponential advances in silicon speed, power and functionality. But with the cost per transistor rising for the first time in history, weve entered an era of diminishing returns. <\/p>\n
We need to get smarter about hardware and software innovation in order to get the most value from the emerging Internet of Things. And perhaps the smart thing to do is to hit pause on the half-century race to cram ever more transistors onto a single slice of silicon. <\/p>\n
If we are to achieve the vision of connecting tens of billions of devices to the Internet Cisco predicts 40 billion smart objects and another 10 billion traditional devices and machines with embedded smarts were going to need a huge supply of low-cost chips with communications capabilities. The good news is that innovation and growth can continue at the same pace but only if we take a break from the relentless pressure of doubling the transistor count every two years. <\/p>\n
To date weve kept pace with Moores Law by shrinking chip features, or nodes, to ever-smaller, nanoscale dimensions. (How big is a nanometer? Its about as long as your fingernail grows in one second. Slice a human hair lengthwise about 100,000 times, and thats a nanometer.) The cost-effectiveness ratio seems to have hit the sweet spot at about 28 nanometers. Each incremental advance beyond that has required ever-greater investments, reducing the bang-per-buck calculus. <\/p>\n
Chips will continue to shrink, of course. We, along with other semiconductor companies are continuing to push toward the next goal of 10nm, but going beyond 10nm will require the development of new technologies, materials, and manufacturing processes that are still being perfected. Extreme Ultraviolet (EUV) lithography, exotic semiconductor materials, multiple 3D chip-stacking and 450mm wafers are just a few of the new, breathtakingly expensive avenues of research. <\/p>\n
However, there are many levers we can pull with 28nm silicon to propel the industry forward and enable the Internet of Things era of innovation and growth from literally thousands of developers. We can drive cost, size, and power-efficiency improvements through better design engineering versus better process engineering. IoT devices typically have much smaller transistor counts and therefore dont require the latest (and most expensive) process nodes. <\/p>\n
Adhering to the premise that 28nm is the optimum node size, then solidifying that node as the platform of choice and integrating more functionality, such as analog and RF components, is the next logical step. Analog components dont scale as well as digital components, but integrating them into relatively mature 28nm platforms will accelerate the connection of everything from watches, personal healthcare, and home appliances to automotive, transportation, agriculture, manufacturing, and industrial controls. <\/p>\n
As an industry, we have access to low-cost hardware, from sensors to signal conditioners and wireless interfaces. Innovators are developing the ideas and bringing them to life in amazing new applications. All we, as an industry, need to do now is focus on standardizing the interfaces to ensure interoperability and stand out of the way. Even with Moores Law on pause, the best days of the semiconductor industry are yet ahead. <\/p>\n
