ASMPT Limited secures repeat order for eight TCB tools from major client
ASMPT Limited just locked in another order for eight Thermo-Compression Bonding tools from one of the world’s largest chip manufacturers. The deal, announced on June 8, covers chip-to-wafer configurations used to build next-generation CPUs with chiplet-based architectures.
This isn’t a one-off win. ASMPT secured two separate orders in late 2025, totaling 34 chip-to-substrate TCB tools dedicated specifically to AI chip manufacturing. The company now holds sole-supplier status, known in the industry as Process of Record, for multiple programs across AI chips and high-bandwidth memory stacking.
Why TCB tools matter more than you think
ASMPT’s installed base now exceeds 500 TCB tools worldwide. The company commands an estimated 35-40% market share in advanced packaging. Group CEO Robin Ng has projected that the total addressable market for TCB technology will exceed $1 billion by 2027, driven almost entirely by artificial intelligence and high-performance computing.
The AI packaging arms race
On December 3, 2025, ASMPT received an order for 19 chip-to-substrate TCB tools. Less than three weeks later, on December 22, another 15 tools followed. Both were earmarked for AI chip production. Now, six months later, the same playbook is repeating with chip-to-wafer tools for CPU manufacturing.
Beyond bonding chips to substrates and wafers, ASMPT has been advancing its capabilities in high-bandwidth memory stacking. The company’s fluxless Active Oxide Removal technology, first demonstrated for HBM 16H stacks in December 2024, represents a technical capability for stacking 16 layers of HBM dies cleanly and reliably.
What this means for investors
The projected $1 billion TAM for TCB technology by 2027 provides a useful benchmark. If ASMPT maintains even its current market share, that translates to $350-400 million in TCB-related revenue from a single product category.

The AI boom may follow the path of the 19th-century railway bubble, and builders may not be the ultimate winners
Goldman Sachs analyst Bobby Molavi compared the current situation to the 19th-century British railway mania: 500 companies spent more than the nation's annual income building 8,000 miles of railway, with most early investors losing out, while the real beneficiaries were the later "passengers." He pointed out that the current AI craze is driven by both debt and momentum, and that the S&P 500’s forward P/E ratio of 18x is only "a bit cheaper." Whether the builders can retain value is uncertain, and history does not offer an optimistic answer.
If Anthropic's IPO goes smoothly and the stock price rises next week, then everything remains the same for AI. Otherwise, some companies will go bankrupt.
The shrinking valuations of two major giants have triggered a chain reaction—investors are adopting more conservative revenue multiples for AI startups and are directly halting high-valuation financing for companies with zero revenue. Multiple venture capital firms have advised their portfolio companies to lower valuation expectations and to quickly build up cash reserves. Market participants warn that the outcome of Anthropic’s IPO will be a barometer for the industry: if successful, the boom will continue; if it fails, some companies may face elimination.

For Corning, the recent profit growth mainly comes from the expansion of AI clusters. As the number of optical links crossing cabinets and campuses increases, customers need to deploy more optical fibers within limited conduit and cabinet space, thus driving demand for high-density optical cables and connection systems.
