Asahi Kasei completed a new photosensitive dry film resist factory at its Taiwan subsidiary on July 3, 2026, expanding slitting capacity by approximately 1.4 times to meet growing AI semiconductor demand. The facility, which cost about 2 billion yen, will begin commercial operations later that month and can scale to roughly double production through additional equipment installation, positioning the company to serve customers faster and more reliably in a market where material quality directly affects chip performance.

旭化成は2026年7月3日、台湾子会社の華旭科技が建設していた感光性ドライフィルムレジスト「サンフォート™」のスリット加工新工場を竣工したと発表しました。投資額は約20億円で、同月中に順次商業運転を開始する予定です。
なぜ重要か
AI向け半導体需要の拡大に伴い、先端半導体パッケージ向け材料の供給が逼迫しています。台湾で生産体制を強化することで、顧客への納期短縮と供給安定化が期待されます。半導体では材料の品質が最終製品の性能に影響するため、こうした体制整備は競争力向上につながる可能性があります。
注目点
稼働後、華旭科技全体のスリット加工能力が従来比約1.4倍へ拡大します。設備増設により最大約2倍まで生産能力を引き上げられる設計となっており、中長期的な需要増に対応できます。一方、半導体業界は市場環境変化による需要変動リスクも抱えています。
The Taiwan factory expansion reflects Asahi Kasei's response to a structural shift in semiconductor demand. As AI adoption increases data processing volumes, advanced semiconductor packages require higher-performance materials, creating supply pressures that the body describes as expanding rapidly. By investing in production capacity closer to customers in Taiwan—where semiconductor packaging companies cluster—Asahi Kasei aims to shorten lead times and stabilize supply while meeting increasingly stringent quality standards that affect chip yield and performance.
The design flexibility built into the facility (capacity that can scale to roughly double initial levels) suggests the company is hedging against both upside growth scenarios and demand volatility. The body acknowledges this risk explicitly: semiconductor industries face sensitivity to economic cycles and capital spending, meaning demand can fluctuate if market conditions change. However, if AI-driven semiconductor growth continues, related materials demand (not only photosensitive dry film resist but also adjacent materials like photosensitive insulators and glass cloth) may expand over the medium to long term. The body frames this as a bet on sustained AI market growth, though acknowledges that lower-than-expected demand growth could pressure equipment utilization and investment recovery.
