Key Takeaways
- Taiwan Semiconductor’s stock climbed 5% following the reveal of its A13 and N2U chip fabrication technologies during its technology event in Santa Clara.
- The A13 process focuses on AI chip manufacturing starting in 2029, while N2U offers a more cost-effective solution for smartphones, laptops, and AI beginning in 2028.
- The chipmaker will bypass ASML’s expensive new “high NA” EUV lithography systems, opting to maximize capabilities of current EUV tools instead.
- TSMC’s 2028 roadmap includes the ability to package 10 large chips with 20 memory stacks — a significant increase from today’s two chips and eight stacks.
- Shares of ASML fell 1% following the announcement, as TSMC’s strategy signals reduced immediate demand for its premium machinery.
Taiwan Semiconductor Manufacturing Co. (TSM) presented its forward-looking chip manufacturing roadmap at its annual technology symposium in Santa Clara on April 22, 2026. Investors responded enthusiastically, pushing shares up 5% by market close.

The centerpiece of the presentation featured two new manufacturing processes: A13 and N2U. The A13 node represents an evolution of TSMC’s current A14 technology and specifically targets artificial intelligence chip manufacturing, with mass production slated for 2029. Meanwhile, N2U serves as the budget-friendly alternative, designed for mobile devices, personal computers, and AI systems starting in 2028.
While both technologies promise to deliver smaller and faster semiconductor components, the individual chip performance improvements are characterized as incremental rather than revolutionary.
Perhaps the most significant revelation concerns what TSMC chose not to purchase. The semiconductor giant announced it will forgo ASML’s latest “high NA” extreme-ultraviolet lithography equipment for the foreseeable future. Each of these cutting-edge machines carries a $400 million price tag — approximately twice the cost of the current-generation EUV systems TSMC currently operates.
Kevin Zhang, TSMC’s deputy co-chief operations officer, explained to Reuters that the company’s research and development efforts have identified methods to extract additional capabilities from existing EUV technology. “This is definitely a strength,” Zhang stated.
ASML’s stock price declined approximately 1% in response to the news. Reduced urgency for equipment upgrades translates to potential short-term challenges for the Netherlands-based semiconductor equipment manufacturer.
Advanced Multi-Chip Integration
The packaging innovations announced Wednesday garnered considerable interest as well. TSMC revealed that by 2028, it will possess the capability to integrate 10 large computing chips alongside 20 high-bandwidth memory stacks within a single package. For context, contemporary AI processors such as Nvidia’s Vera Rubin — manufactured by TSMC with an expected 2026 release — utilize just two large chips paired with eight memory stacks.
This multi-chip integration approach represents the industry’s primary strategy for sustaining performance improvements as traditional transistor miniaturization reaches physical limitations. Dan Hutcheson from TechInsights characterized this evolution as Moore’s Law “morphing from a monolithic, single die in a package to multi-die in a package.”
However, advanced chip stacking presents substantial engineering challenges. Thermal accumulation and mechanical stress from different materials experiencing varying rates of thermal expansion can result in package warping or fractures. Ian Cutress from More Than Moore pointed out that Nvidia’s Rubin processor encountered precisely these types of complications. He noted that TSMC’s presentation did not specifically detail its proposed solutions to these technical obstacles.
Valuation and Market Position
TSMC currently trades at a P/E ratio of 32.18x and receives a GF Score of 96 out of 100. Insider transaction data from the previous 12 months indicates 33 purchases against zero sales.
Notwithstanding these strong indicators, GuruFocus’s GF Value model currently categorizes the stock as “significantly overvalued.”
Major customers for TSMC’s upcoming manufacturing processes include Apple, Nvidia, AMD, and Google. The company maintains approximately 70% market share of the worldwide semiconductor foundry industry.
ASML confirmed the 1% decrease in its share price on the day TSMC made its announcement.
