Bottom layer structures are around 100nm thick and represent what the transistors underneath look like. Each layer has connections to another layer. The structures you can see here are just several layers of this CPU. And with AMD's next CPUs on TSMC's 7nm process, this marks a chance for them to jump past Intel in performance, and bring some healthy competition to Intel's monopoly on the market-at least until Intel's 10nm "Sunny Cove" chips start hitting shelves. This is an Intel Core 2 Duo CPU that has been crushed with pliers and put in the scanning electron microscope. With Intel lagging, even mobile devices have had a chance to catch up, with Apple's A12X chip being manufactured on TSMC's 7nm process, and Samsung having their own 10nm process. Si vous limitez cela aux dispositifs à semi-conducteurs et à lunité de traitement proprement dite, alors oui, un processeur est composé de transistors. Cela dépend de ce que vous entendez par «composant électronique» et «CPU». These new processes are the first major shrinks in a long time, especially from Intel, and represent a brief rekindling of Moore's law. Oui, le processeur est entièrement composé de transistors et de fils. But further shrinking has gotten more complicated, and we haven't seen a transistor shrink from Intel since 2014. The wells convert the silicon into the correct type for building the transistor (you need to build an N channel MOSFET on P type silicon, and a P channel MOSFET on N type silicon). Back in the late 90s and early 2000s, transistors shrunk in size by half every two years, leading to massive improvements on a regular schedule. The first step is to lay down the wells in which the transistors are placed. This is breaking it into small pieces that can be placed on the tray of an electron microscope, the only one accurate enough to see the transistors, which is the objective. Moore's Law, an old observation that the number of transistors on a chip doubles every year while the costs are halved, held for a long time but has been slowing down lately. In order to see a processor under the microscope and know what is inside it, it is first necessary to destroy it. So Why Are These New Processes So Important? Le transistor est un composant électronique actif agissant comme un interrupteur commandé. For reference, "10nm" is Intel's new manufacturing process, set to debut in Q4 2019, and "7nm" is usually referring to TSMC's process, which is what AMD's new CPUs and Apple's A12X chip are based on.
