Smaller transistors allow designers to squeeze more of them onto a single chip and adding more of these tiny features roughly translates to an improvement in the chip’s ability to perform calculations. At the atomic scale chips operate at, having better control over the flow of electricity gives designers new options: most importantly, making them even smaller. Surrounding all four sides of a part of the transistor with material instead of the current three-sided design allows the gate to better regulate the flow of electricity. “Gate-all-around-based designs will have significantly better performance and efficiency than designs, potentially shifting the competitive position for many high-performance products,” MLCommons Executive Director David Kanter said. And to build more efficient gates and transistors that generate less power, chipmakers spend billions of dollars inventing the next, better way to develop them. “There’s a rule of thumb that the smaller you get, the more current leakage you’re going to get, which is more heat.”īecause chipmakers know some electricity will evade the gate, it’s becoming harder to continue to shrink features to achieve the power consumption and performance expected of new designs. “As you start making things smaller, you learn that there are some electrical characteristics with smaller elements that didn’t work as well as they did when they were bigger,” FeibusTech analyst Mike Feibus said. ![]() But gates, like hoses, can be imperfect, and some of the electricity can slip through even with the most advanced designs. To that end, Intel and others have been advancing the design of the transistors, particularly in the way the gates are designed.” Better gates, faster chipsĪ gate is the tiny portion on each transistor that controls whether a transistor receives electricity - kind of like using your foot on a garden hose to turn water on or off - in order to represent the zeros and ones that make up bits of data. “I’d argue that even more important is the design of the transistors themselves, and not just the process node. “Process nodes are just one measure of the progress,” Jack Gold, principal analyst at J.Gold Associates, said. Typically manufacturers tout improvements to their techniques and technologies as process nodes that use smaller and smaller nanometer numbers.īut another way to tackle the increasingly difficult problem is to further refine the fundamental building block of each chip: the transistor. ![]() “The rate at which we're shrinking is for sure slowing down, big time,” Applied Materials Vice President Kevin Moraes said.Ĭhip manufacturers improve high-volume production and performance with a combination of advanced tools such as extreme ultraviolet lithography machines and techniques that help squeeze more features onto each piece of silicon. ![]() This process, loosely described as Moore’s law, has kept the chip industry humming for a half-century, but it’s getting harder. That means making already atomic-sized features even smaller. Doing so requires some of the most complex, expensive manufacturing equipment on the planet, and the development of even more creative ways to improve fundamental aspects of chip construction. In 2025, Gartner expects chip manufacturers to generate roughly $5 billion in revenue from the new technology, up from nothing last year.Ĭhip companies must deliver substantially more computing horsepower every year to get to a version of the future that’s been promised by the tech titans. Modern chips can have upwards of 30 billion transistors on a single device, and in some cases tens of billions more. This next-generation design is called “gate-all-around.” With new materials, and redesigned manufacturing tools that cost tens of millions each, the new gates accomplish one thing: They more tightly control the flow of electricity received by each transistor. This leap must occur to realize anything close to the computing requirements demanded by the ideas behind the metaverse, to produce AI that isn’t a joke, to make truly self-driving cars or even make apps load faster. Intel, Samsung and TSMC are racing to achieve a generational leap in transistor technology. A once-in-a-decade shift is underway involving one of the most elemental building blocks of computer chips, and it has the potential to reshuffle the pecking order of chip giants for years to come. ![]()
