Key Takeaways
- Taiwan Semiconductor’s stock climbed 5% following the announcement of its A13 and N2U chip manufacturing technologies at its technology symposium in Santa Clara.
- The A13 process focuses on artificial intelligence chip manufacturing beginning in 2029; N2U offers a more economical alternative for smartphones, personal computers, and AI applications starting in 2028.
- The chipmaker intends to bypass ASML’s expensive next-generation “high NA” EUV lithography systems, opting instead to maximize efficiency from current EUV technology.
- TSMC projects the capability to integrate 10 large computing chips with 20 memory stacks by 2028 — a significant increase from today’s configuration of two chips and eight stacks.
- ASML shares declined 1% following TSMC’s announcements, as the roadmap signals reduced immediate demand for its latest, more expensive lithography equipment.
Taiwan Semiconductor Manufacturing Co. (TSM) presented its latest technological advancements during its yearly technology symposium in Santa Clara on April 22, 2026, introducing its upcoming chip manufacturing processes. Shares concluded the trading session with a 5% gain.

The primary reveals centered on the A13 and N2U manufacturing nodes. The A13 process represents an enhancement of TSMC’s current A14 technology and specifically targets AI chip manufacturing, with mass production anticipated in 2029. The N2U node serves as the more budget-friendly alternative, designed for mobile devices, laptops, and artificial intelligence uses beginning in 2028.
Both technologies aim to deliver smaller, more efficient chips. However, the performance improvements at the individual chip level are characterized as incremental rather than revolutionary.
The more significant development may concern what TSMC has chosen not to purchase. The semiconductor manufacturer announced its decision to forgo ASML’s latest “high NA” extreme-ultraviolet lithography equipment for the foreseeable future. These advanced machines carry a price tag of approximately $400 million per unit — essentially double the cost of the older EUV systems TSMC currently utilizes.
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 capability from existing EUV technology. “This is definitely a strength,” he stated.
ASML shares dropped approximately 1% in response to the announcement. Reduced pressure to acquire upgraded equipment translates to near-term challenges for the Dutch semiconductor equipment manufacturer.
Advanced Multi-Chip Integration
The packaging innovations presented on Wednesday also captured significant interest. TSMC announced that by 2028, it will achieve the capability to integrate 10 large computing chips alongside 20 high-bandwidth memory stacks within a single package. Contemporary AI processors such as Nvidia’s Vera Rubin — manufactured by TSMC and scheduled for release this year — incorporate two large chips with eight memory stacks.
This multi-chip integration approach represents the industry’s primary strategy for maintaining performance growth as improvements from traditional transistor miniaturization decelerate. Dan Hutcheson of TechInsights characterized this evolution as Moore’s Law “morphing from a monolithic, single die in a package to multi-die in a package.”
However, chip stacking presents distinct engineering challenges. Thermal accumulation and the mechanical stress resulting from different materials’ varying thermal expansion rates can lead to package warping or fractures. Ian Cutress of More Than Moore observed that Nvidia’s Rubin processor had encountered precisely these types of complications. He noted that TSMC did not explicitly detail its solutions to these challenges.
Solid Metrics, Elevated Valuation
TSMC trades at a P/E ratio of 32.18x and maintains a GF Score of 96 out of 100. Insider transactions over the preceding 12 months reveal 33 purchases with zero sales.
Notwithstanding these favorable indicators, the stock currently receives a “significantly overvalued” classification according to GuruFocus’s GF Value assessment model.
TSMC’s customer base for these advanced processes encompasses Apple, Nvidia, AMD, and Google. The semiconductor foundry commands approximately 70% of the worldwide foundry market.
ASML verified the 1% decline in its share price on the day TSMC made its announcements.
