Japan METI supply-security-plan grant: up to JPY 2.2bn for JX Metals copper sputtering-target capacity

Mechanism

JX Metals (JX Nippon Mining & Metals Corporation, corporate parent of the now-independently-listed JX Advanced Metals) holds roughly 50-60% of the global market for semiconductor sputtering targets — thin metal plates (copper, copper alloy, titanium, tantalum) that are the source material for depositing wiring layers onto silicon wafers. METI's Supply Security Plan mechanism (under the 2022 Economic Security Promotion Act, see 2022-05-18-japan-economic-security-promotion-act) lets a company file a plan committing to a minimum continuous-production period for a designated "specified critical good" in exchange for a capex grant.

This is plan certification No. 1 in the 2025 semiconductor tranche (2025半導体第1号-1), the first of the tranche and the one later referenced by No. 2 (DIC Corporation epoxy resin, see 2025-07-31-japan-meti-dic-corporation-semiconductor-epoxy-resin-grant) and No. 3 (Nitto Boseki glass cloth, see 2025-08-07-japan-meti-nitto-boseki-glass-cloth-supply-security-grant).

The certified project: capacity expansion for advanced copper-based sputtering targets at JX Metals' Hitachinaka plant (Ibaraki Prefecture), against a required investment of roughly JPY 6.6 billion, with a maximum grant of roughly JPY 2.2 billion (~USD 14.8m), and a commitment to continuous production for 10+ years from supply start.

Severity is set low (2/5, quant) — this is a single-company capex subsidy of modest absolute size (~USD 15m), not a trade-restrictive measure. It is filed as the first concrete data point in the 2025 semiconductor tranche of Japan's ESPA supply-chain-resilience program, anchoring the sputtering-target layer of Japan's semiconductor-materials chokepoint mapping alongside the epoxy-resin and glass-cloth certifications that followed it.

Downstream implications

• Confirms copper-based sputtering targets are formally designated under

Japan's specified-critical-goods regime — the first plan (No. 1-1) in the 2025 semiconductor tranche, preceding DIC (epoxy resin, plan 2) and Nitto Boseki (glass cloth, plan 3).

• JX Metals' global share of sputtering-target supply (~50-60%) makes this

a materials-chokepoint-relevant subsidy: domestic Japanese capacity expansion reduces single-firm concentration risk for a wiring-layer input with few alternative suppliers (Honeywell, Praxair Surface Technologies are the main non-Japanese competitors).

• First confirmed plan in the 2025 semiconductor tranche; watch METI's

semicon hub page for further tranche certifications (plan numbers 2025半導体第4号 onward).

Open questions

• Whether later 2025-tranche certifications beyond JX Metals (plan 1), DIC

(plan 2), and Nitto Boseki (plan 3) name other materials chokepoints worth tracking individually.

• Actual disbursed amount vs. the certified maximum grant, once METI

publishes execution data. </content>
