Taiwan Semiconductor Manufacturing Co. (TSMC) has chosen nanosheet know-how for manufacturing of its subsequent 2 nm node beginning in 2025 to assist minimize power consumption in excessive–efficiency computing (HPC) methods.
The corporate will comply with rivals Samsung and Intel, which plan to roll out their very own nanosheet gadgets as early as this 12 months.
TSMC briefed a handful of reports media on its roadmap for the following few years as a preview for its annual know-how symposium, which will likely be held at a number of international areas within the coming months. The world’s main chip foundry is evaluating different course of applied sciences reminiscent of complementary FET (CFET) to comply with nanosheet, based on Kevin Zhang, TSMC vice chairman of Enterprise Improvement.
CFET is an evolution of nanosheet know-how. As a substitute of stacking both n–kind or p–kind gadgets, it locations each on high of one another to attain greater transistor density. TSMC is looking for new transistor architectures that assist scale back power consumption in HPC functions, reminiscent of knowledge facilities, which are including considerably to international warming.
“This (CFET) remains to be on the analysis part,” Zhang advised EE Instances. “This is only one transistor possibility. I don’t assume I can give you a timeline for when this transistor know-how will go into manufacturing.”
Additional alongside TSMC’s know-how roadmap are new supplies underneath analysis like tungsten disulfide. The fabric supplies higher conduction and extra power–environment friendly computation, Zhang stated. Additionally underneath analysis is carbon nanotube, a fabric that strikes electrons extra effectively, he added.
“We imagine all these new gadgets and supplies will assist us to maneuver know-how scaling ahead,” Zhang stated. Power effectivity and low energy consumption have “clearly” change into the brand new benchmark for the long run, he famous, as Moore’s Regulation wanes in significance.
The corporate will begin manufacturing of its business–main 3 nm node later this 12 months, which can mark the tip of the FinFET course of know-how that supplied TSMC a 90% share of the 5 nm enterprise, based on market analysis agency Gartner. There will likely be an approximate three–12 months cadence between 3 nm and a pair of nm.
“We do imagine 3 nm will likely be an extended node. We are going to proceed to see excessive–quantity demand on that node. However when it comes to transition from 3 nm to 2 nm… nanosheet has a singular benefit when it comes to additional enhancing power and computational effectivity due to the transistor structure. We’d anticipate prospects with merchandise that require extra power effectivity when it comes to computational requirement, they are going to transfer to 2 nm first.”
Samsung would be the first to introduce nanosheet know-how within the second half of this 12 months on the 3 nm node. That transfer could also be untimely, based on Bernstein analyst Mark Li.
“Samsung is the primary and is adopting nanosheet now, however that on opposite has scared prospects like Qualcomm and Nvidia away to TSMC as these prospects fear about execution dangers,” Li advised EE Instances. “Intel’s plan can be sooner than TSMC’s, most likely by round one 12 months, however once more whether or not Intel can execute is a separate matter. Commercializing new tech with predictable high quality, yield, and therefore value and quantity requires a cautious judgment on tech readiness and execution capabilities, and that’s the place TSMC actually differentiates.”
Some TSMC prospects might keep at 3 nm even longer simply to attempt to harvest extra know-how advantages, Zhang defined. “3 nm and a pair of nm will overlap [and] co–exist for fairly a while,” he stated.
Migrating foundry prospects from FinFET to a brand new know-how like nanosheet will likely be dangerous. TSMC has a monitor report that prospects discover reassuring, based on Matthew Bryson, senior vice chairman at Wedbush Securities.
“Current historical past definitely favors TSMC, however on the identical time, the aggressive panorama has modified with Intel prepared to speculate considerably greater than had been the case underneath the previous few administrations and trying to lead with new know-how,” Bryson stated.
