Taiwan Semiconductor Manufacturing Co. (TSMC), the world's largest contract chipmaker, is charting its next technological leap even as its latest earnings shook markets across Asia.

The company said commercial production of its highly anticipated A14 process is slated to begin in 2028, according to a news report by Focus Taiwan. The A14 name refers to a future generation of TSMC's manufacturing technology — the ultra-fine process used to pack more computing power into the chips that run smartphones, data centers, and artificial-intelligence systems.

While that 2028 target looks toward the long term, TSMC's earnings had a more immediate effect. According to finance.biggo.com, the Nikkei 225 — Japan's benchmark stock index — plunged more than 2,900 points and broke below 64,000, with TSMC's results described as sparking a broad semiconductor selloff. Chip-related shares tend to move together, so a single major report from an industry bellwether can ripple through the whole sector.

The two developments capture the split-screen nature of the chip industry right now. On one side is a company confident enough to publicly commit to a production roadmap years out. On the other is a market so sensitive to semiconductor news that a single earnings release can wipe thousands of points off a national index in a day.

The sources here do not detail the specific earnings figures behind the market reaction, nor the technical performance gains A14 is expected to deliver, so those specifics remain unconfirmed in this reporting.

Why it matters: TSMC makes the advanced chips that power much of the modern economy, so both its long-term technology plans and the market's reaction to its results signal where the AI-driven tech boom — and investor confidence in it — may be heading.
