Key Takeaways
- TSMC has reached maximum production capacity amid explosive AI chip demand, according to Broadcom
- Supply constraints are projected to continue through 2026, with capacity expansion targeted for 2027
- Component shortages now extend beyond semiconductors to include lasers and PCBs
- Printed circuit board delivery times have ballooned from 6 weeks to 6 months for optical transceiver applications
- Tech firms are securing 3–5 year supply contracts to guarantee component access
Semiconductor giant Broadcom has issued a stark warning about intensifying supply chain pressures across the technology industry, specifically identifying manufacturing partner TSMC as a critical production constraint. The alert came Tuesday from Natarajan Ramachandran, who serves as director of product marketing within Broadcom’s Physical Layer Products division.
Speaking with media representatives, Ramachandran revealed that TSMC is “hitting production capacity limits.” He noted that merely a few years earlier, he would have characterized TSMC’s manufacturing capability as “infinite” — a description that no longer applies.
TSMC serves as the primary manufacturer of cutting-edge AI semiconductors globally. The company’s client roster includes industry leaders such as Broadcom, Nvidia, and Apple. In January, the Taiwanese semiconductor foundry confirmed strained capacity levels and indicated efforts to narrow the supply-demand imbalance.
Ramachandran stated that TSMC has outlined capacity expansion plans extending through 2027. However, this growth trajectory hasn’t kept pace with demand. “That has become a bottleneck, or that has kind of choked the supply chain in 2026,” he explained.
The supply crunch extends well beyond chip manufacturing. Ramachandran indicated that capacity limitations are now rippling through related technology infrastructure components.
He highlighted constraints in laser component availability, observing that despite multiple vendors operating in this market segment, production capacity remains insufficient. Printed circuit boards have also unexpectedly become a constraint point.
Printed Circuit Board Delivery Times Explode
PCBs utilized in optical transceiver manufacturing are experiencing lead time extensions from approximately six weeks to as much as six months. According to Ramachandran, both Taiwanese and Chinese PCB manufacturers are encountering capacity ceilings, though he declined to identify specific suppliers.
This development follows previous reports of supply limitations affecting chipmakers Intel and AMD. Intel’s server product pricing increased approximately 10%, while AMD faced extended delivery schedules. AMD maintained at that time it remained optimistic about fulfilling demand through existing supplier relationships, including its partnership with TSMC.
Extended Supply Agreements Become Industry Standard
Facing these challenges, numerous technology companies are now executing extended supply commitments spanning three to four years. Samsung disclosed last week that it’s similarly transitioning toward longer-duration contracts of three to five years with primary customers.
These contractual arrangements signal a fundamental industry transformation. Buyers seek supply certainty, while manufacturers aim to mitigate demand volatility risks.
Ramachandran indicated he maintains optimism about longer-term prospects. He anticipates that market entry by new manufacturers and capacity additions will gradually alleviate current constraints.
This disclosure follows Broadcom’s recent announcement of a collaboration with OpenAI to produce 10 gigawatts of specialized AI accelerators. Under this arrangement, OpenAI will handle chip and system architecture while Broadcom contributes to development and implementation.
TSMC had not provided comment by publication time.
