AGC Aims to Double Semiconductor Revenue; PTFE Substitution Draws Attention

Overview

This report, based on AGC's semiconductor business briefing, confirms its medium- to long-term growth opportunities. The company targets approximately ¥100 billion in semiconductor-related revenue by FY2025 and doubling to ¥200 billion by FY2030, representing a 15% CAGR. Growth is driven by EUV mask blanks and CCL in the Electronics segment and process materials in the Performance Chemicals segment. The report also discusses the potential substitution of PTFE for low-dielectric glass as a backing material, with a final decision expected after testing in August.

Core views

AGC's semiconductor growth path is clear, with well-defined drivers by segment. In the Electronics segment, EUV mask blank revenue exceeded ¥40 billion in FY2024, setting a record, and is expected to surpass this in FY2026 as customer recovery and expanded customer base continue. The new CCL ELL series combines proprietary resins with lower-grade glass cloth to achieve comparable performance, targeting 224G applications (e.g., switches/routers), and plans to replace quartz glass in the NER glass (Low-Dk2) segment. The Performance Chemicals segment relies on a portfolio of fluorinated products, including FFKM (sealing material for CVD/etching tools, replaced quarterly), ETFE (release film, global market leader), CYTOP (ArF/KrF mask material), and PTFE. As deposition and etching intensity increases with layer count, tool demand growth is expected to outpace the WFE market (projected >20% growth in 2026-2027), positioning AGC to benefit. Regarding the PTFE versus low-dielectric glass debate, market attention is focused on the possible shift to PTFE for Rubin Ultra backing material. The report suggests that due to stringent electrical performance requirements, adoption of M9 specification is unlikely; testing has shifted toward M10, which offers electrical properties similar to PTFE but better compatibility. A final decision is expected after testing concludes in August 2026. AGC acknowledges strong interest in fluorinated materials for backing applications and is actively advancing development.

Analysis framework

The analysis employs a supply-demand framework, integrating company strategic goals with industry technology pathways. It first decomposes growth sources from internal revenue targets and product lines, focusing on dual drivers in Electronics and Performance Chemicals. It then evaluates the material substitution event by comparing technical performance (electrical properties, compatibility) and testing progress between PTFE and low-dielectric glass to assess supply chain implications.

Key data

• Semiconductor Revenue Target (FY2025)Approximately ¥100 billionBaseline year
• Semiconductor Revenue Target (FY2030)¥200 billion15% CAGR
• EUV Mask Blank Revenue (FY2024)>¥40 billionRecord level; expected to be surpassed in FY2026
• WFE Market Growth Expectation~20% YoY+2026-2027

Impact & implications

For AGC, achieving revenue targets will enhance profit contribution. For the industry, the material substitution decision will affect demand for low-dielectric glass suppliers. The test results could trigger stock price volatility; for example, AGC rose 9% on the day while Nittobo and NEG fell approximately 10%.

Risks

• Uncertainty surrounding material substitution test results
• WFE market growth falling short of expectations
• Revenue target achievement dependent on customer recovery

What to watch

• Material test results in August 2026
• Progress in EUV mask blank customer recovery
• Timeline for adoption of back-end materials such as glass cores
