Final week, TSMC issued their This autumn and full-year 2022 earnings studies for the corporate. In addition to confirming that TSMC was closing out a really busy, very worthwhile 12 months for the world’s high chip fab – reserving virtually $34 billion in internet earnings for the 12 months – the end-of-year report from the corporate has additionally given us a recent replace on the state of TSMC’s varied fab tasks.
The massive information popping out of TSMC for This autumn’22 is that TSMC has initiated excessive quantity manufacturing of chips on its N3 (3nm-class) fabrication expertise. The ramp of this node will likely be reasonably sluggish initially attributable to excessive design prices and the complexities of the primary N3B implementation of the node, so the world’s largest foundry doesn’t count on it to be a major contributor to its income in 2023. But, the agency will make investments tens of billions of {dollars} in increasing its N3-capable manufacturing capability as ultimately N3 is predicted to turn into a well-liked long-lasting household of manufacturing nodes for TSMC.
Gradual Ramp Initially
“Our N3 has efficiently entered quantity manufacturing in late fourth quarter final 12 months as deliberate, with good yield,” mentioned C. C. Wei, chief govt of TSMC. “We count on a easy ramp in 2023 pushed by each HPC and smartphone functions. As our clients’ demand for N3 exceeds our skill to produce, we count on the N3 to be absolutely utilized in 2023.”
Maintaining in thoughts that TSMC’s capital expenditures in 2021 and 2022 have been targeted totally on increasing its N5 (5nm-class) manufacturing capacities, it isn’t stunning that the corporate’s N3-capable capability is modest. In the meantime, TSMC doesn’t count on N3 to account for any sizable share of its income earlier than Q3.
In truth, the No. 1 foundry expects N3 nodes (which embody each baseline N3 and relaxed N3E that’s set to enter HVM within the second half of 2023) to account for possibly 4% – 6% of the corporate’s wafer income in 2023. And but this is able to exceed the contribution of N5 in its first two quarters of HVM in 2020 (which was about $3.5 billion).
“We count on [sizable N3 revenue contribution] to begin in third quarter 2023 and N3 will contribute mid-single-digit proportion of our complete wafer income in 2023,” mentioned Wei. “We count on the N3 income in 2023 to be increased than N5 income in its first 12 months in 2020.”
Many analysts consider that the baseline N3 (also referred to as N3B) will likely be utilized by Apple both completely or virtually completely, which is TSMC’s largest buyer that’s keen to undertake modern nodes forward of all different corporations, regardless of excessive preliminary prices. If this assumption is appropriate and Apple is certainly the first buyer to make use of baseline N3, then it’s noteworthy that TSMC mentions each smartphone and HPC (a obscure time period that TSMC makes use of to explain nearly all ASICs, CPUs, GPUs, SoCs, and FPGAs not geared toward automotive, communications, and smartphones) functions at the side of N3 in 2023.
N3E Coming within the Second Half
One of many the explanation why many corporations are ready for TSMC’s relaxed N3E expertise (which is getting into HVM within the second half of 2023, in response to TSMC) is the upper efficiency and energy enhancements, in addition to much more aggressive logic scaling. One other is that the method will supply decrease prices, albeit at the price of a lack of SRAM scaling in comparison with N5, in response to analysts from China Renaissance.
“N3E, with six fewer EUV layers than the baseline N3, guarantees easier course of complexity, intrinsic value and manufacturing cycle time, albeit with much less density acquire,” Szeho Ng, an analyst with China Renaissance, wrote in a word to shoppers this week.

Ho says that TSMC’s authentic N3 options as much as 25 EUV layers and might apply multi-patterning for a few of them for extra density. By contract, N3E helps as much as 19 EUV layers and solely makes use of single-patterning EUV, which reduces complexity, but in addition means decrease density.
“Shoppers’ curiosity within the optimized N3E (publish the baseline N3B ramp-up, which is basically restricted to Apple) is excessive, embracing compute-intensive functions in HPC (AMD, Intel), cellular (Qualcomm, Mediatek) and ASICs (Broadcom, Marvell),” wrote Ho.
It seems to be like N3E will certainly be TSMC’s primary 3nm-class working horse earlier than N3P, N3S, and N3X arrive afterward.
Tens of Billions on N3
Whereas TSMC’s 3nm-class nodes are going to earn the corporate just a little greater than $4 billion in 2023, the corporate will spend tens of billions of {dollars} increasing its fab capability to provide chips on varied N3 nodes. This 12 months the corporate’s capital expenditures are guided to be between $32 billion – $36 billion. 70% of that sum will likely be used on superior course of applied sciences (N7 and beneath), which incorporates N3-capable capability in Taiwan, in addition to tools for Fab 21 in Arizona (N4, N5 nodes). In the meantime 20% will likely be used for fabs producing chips on specialty applied sciences (which primarily means a wide range of 28nm-class processes), and 10% will likely be spent on issues like superior packaging and masks manufacturing.
Spending no less than $22 billion on N3 and N5 capability signifies that TSMC is assured on the demand for these nodes. And there’s a good cause for that: the N3 household of course of applied sciences is ready to be TSMC’s final FinFET-based household of manufacturing nodes for complicated high-performance chips. The corporate’s N2 (2nm-class) manufacturing course of will depend on nanosheet-based gate-all-around field-effect transistors (GAAFETs). In truth, analyst Szeho Ng from China Renaissance believes {that a} important share of this 12 months’s CapEx set for superior applied sciences will likely be spent on N3 capability, setting the bottom for roll-out of N3E, N3P, N3X, and N3S. Since N3-capable fabs can even produce chips on N5 processes, TSMC will be capable to use this capability the place there will likely be important demand for N5-based chips as nicely.
“TSMC guided 2023 CapEx at $32-36bn (2022: US$36.3bn), with its enlargement targeted on N3 in Fab 18 (Tainan),” the analyst wrote in a word to shoppers.
Since TSMC’s N2 course of expertise will solely ramp beginning in 2026, N3 will certainly be a long-lasting node for the corporate. Moreover, since it will likely be the final FinFET-based node for superior chips, it will likely be used for a few years to come back as not all functions will want GAAFETs.
