TSMC has reached a 98% yield on its CoWoS-L packaging technology enabling mass production of 5.5x reticle size chips, and is on track to package up to 14x reticle size silicon by 2029 with its A13 node. The company is also advancing its SoIC hybrid bonding technology to further increase interconnect density and energy efficiency.
This Wire brief sits within Fusion42's coverage of Semiconductors. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ ◆ The Wire takeaway
TSMC's progress means semiconductor founders can now design much larger chips with confidence in packaging yields, opening new opportunities in chip complexity and integration this year and looking ahead to 2029. You need to prepare for collaboration closely with TSMC to leverage advanced packaging or risk missing the leap in performance and scale it enables.
