Taiyo Holdings stock advances its advanced packaging push
Published on 09/29/2026 at 22:20 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Taiyo Holdings stock is linked to a new advanced-packaging milestone after the company achieved a 700 nm critical dimension on 12-inch wafers. The result gives its semiconductor-materials business a concrete technology marker as the company develops its FPIM Series for next-generation redistribution layers.
700 nm milestone advances packaging
According to PR Newswire on September 10, 2026, Taiyo Holdings presented research developed with imec at the IEEE Electronics System-Integration Technology Conference. The FPIM Series formed a three-layer redistribution structure on 12-inch wafers, reaching 700 nm for both interconnects and vias.
The company is targeting a critical dimension of 500 nm or less and began shipping small-volume samples for research and development applications in 2025, according to the same September 10, 2026 release from PR Newswire.
Quarterly revenue reaches JPY 39.0 billion
For the quarter ended June 30, 2026, Taiyo Holdings generated revenue of JPY 39,019.0 million and net income of JPY 7,508.0 million. Investing.com reports that revenue increased from JPY 34,109.0 million in the previous quarter, a plus 14.39 percent comparison, while net income rose from JPY 6,564.0 million, a plus 14.38 percent comparison.
The latest quarter also produced basic earnings per share of JPY 67.40. Those figures place the technology milestone alongside a measurable improvement in operating scale, although the packaging research remains a development-stage opportunity rather than a disclosed revenue forecast.
Stock stays inside its yearly range
Taiyo Holdings was last at JPY 4,777.00 on the Tokyo Stock Exchange on September 29, 2026 at 3:30 p.m. JST. Its market capitalization was JPY 531.6 billion, while the 52-week range stood at JPY 3,700.00 to JPY 6,275.00 on the same date.
The price was 23.89 percent above the 52-week low and 23.87 percent below the 52-week high. For investors, the key test is whether the FPIM research can progress from sample shipments toward commercial adoption while the broader electronics and medical businesses continue to support the group.
