Key Takeaways
- Taiwan Semiconductor’s stock climbed 5% following the announcement of its A13 and N2U chip technologies at a Santa Clara tech event.
- The A13 process focuses on AI chip manufacturing starting in 2029, while N2U offers a cost-effective solution for smartphones, computers, and AI applications beginning in 2028.
- The chipmaker will bypass ASML’s expensive next-generation “high NA” EUV systems, opting to maximize existing EUV technology instead.
- TSMC announced capabilities to integrate 10 large computing chips with 20 memory stacks by 2028, compared to today’s limit of two chips and eight stacks.
- ASML shares declined 1% following TSMC’s announcement, reflecting reduced immediate demand for its advanced equipment.
On April 22, 2026, Taiwan Semiconductor Manufacturing Co. (TSM) presented its latest chip manufacturing innovations at its yearly technology conference in Santa Clara. Shares surged 5% by market close.

The primary highlights included two new manufacturing processes: A13 and N2U. The A13 node represents an evolution of TSMC’s current A14 technology, specifically designed for AI chip manufacturing with mass production scheduled for 2029. Meanwhile, N2U serves as a budget-friendly alternative, directed toward smartphone, laptop, and AI sectors starting in 2028.
While both processes promise to deliver smaller and faster semiconductors, the performance improvements at the individual chip level are characterized as incremental.
Perhaps more significant is TSMC’s strategic decision regarding equipment purchases. The semiconductor giant announced plans to forgo ASML’s latest “high NA” extreme-ultraviolet lithography systems for the foreseeable future. These cutting-edge machines carry a price tag of approximately $400 million per unit — essentially double what TSMC’s current EUV equipment costs.
Kevin Zhang, serving as TSMC’s deputy co-chief operations officer, explained to Reuters that the company’s research and development efforts have identified methods to extract additional capability from current EUV machinery. “This is definitely a strength,” Zhang stated.
ASML’s stock decreased roughly 1% in response to the announcement. The delayed need for equipment upgrades presents short-term challenges for the Netherlands-based lithography specialist.
Advanced Multi-Chip Integration
The packaging innovations unveiled Wednesday also captured significant attention. TSMC revealed that by 2028, its technology will enable the integration of 10 large processing chips alongside 20 high-bandwidth memory stacks within a single package. For comparison, current AI processors such as Nvidia’s Vera Rubin — manufactured by TSMC with an expected release this year — 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 benefits diminish. Dan Hutcheson from TechInsights characterized this shift as Moore’s Law “morphing from a monolithic, single die in a package to multi-die in a package.”
However, chip stacking introduces technical challenges. Thermal accumulation and mechanical stress from different materials expanding at varying rates can lead to package warping or fracturing. Ian Cutress of More Than Moore pointed out that Nvidia’s Rubin processor had encountered precisely these complications. He observed that TSMC did not explicitly outline its solutions to these challenges.
Solid Metrics, Elevated Valuation
TSMC trades at a P/E ratio of 32.18x and holds a GF Score of 96 out of 100. Over the previous 12 months, insider transactions show 33 purchases against zero sales.
Despite these positive indicators, GuruFocus’s GF Value model currently categorizes the stock as “significantly overvalued.”
Major customers for these emerging processes include Apple, Nvidia, AMD, and Google. TSMC maintains approximately 70% control of the worldwide foundry market.
ASML verified the 1% decline in its share price on the day TSMC made its announcement.
