TSMC will Start Mass Production of a Generation of 3nm Chips this Week

Views : 133
Update time : 2023-01-05 10:08:43
        TSMC, the world's largest chip foundry, is about to kick off mass production of cutting-edge chips using its 3nm process. Simply put, as the number of process steps decreases, the transistors used to build these integrated circuits become smaller, allowing more transistors to fit in a small, dense space like a chip. The more transistors a chip has, the more powerful it becomes and the more energy efficient it becomes.
        For example, the A13 Bionic used to equip the 2019 iPhone 11 series was produced using TSMC's enhanced 7nm process node. the SoC packs 8.5 billion transistors. This year's A16 Bionic is manufactured by TSMC using its 4nm process node and has nearly 16 billion transistors.
        Apple is TSMC's largest customer, accounting for 25 percent of the company's revenue. According to Digitimes, an overseas tech forum, writes that this week, TSMC is expected to start mass-producing components using the 3nm process; Apple may use its 3nm M2 Pro chip for the MacBook Pro and Mac Mini before the A17 Bionic makes its way to the iPhone 15 Pro and iPhone 15 Ultra. 
        This Thursday, TSMC is expected to mark the start of 3nm volume production with a ceremony at Fab 18 in the Southern Taiwan Science Park. At the event, TSMC will discuss its plans to expand 3nm production at the facility. Both the A17 Bionic and M3 chips, which are expected to ship later next year, are manufactured using TSMC's enhanced 3nm process.
        The only foundry in the world currently capable of 3nm volume production is the Samsung foundry, using a ring-gate (GAA) transistor architecture that allows more precise control of the current flowing through each transistor. This is achieved by having the gates (which open and close to allow or stop the flow of current) in contact with all the side channels. With the GAA, power supply efficiency is improved. Simply put, a chip using GAA transistors runs faster and consumes less power than a chip using FinFET transistors. However, the current Samsung 3nm GAA process has certain defects, resulting in a yield that does not meet expectations.
