8-K: Navitas Semiconductor Secures New GaN Wafer Supply with Powerchip as TSMC Exits Production

Navitas Semiconductor announced a strategic partnership with Powerchip Semiconductor Manufacturing Corporation to diversify its gallium nitride wafer supply chain after its sole supplier, TSMC, confirmed it would cease GaN production by July 2027.

Summary

• Navitas Semiconductor will diversify its gallium nitride (GaN) wafer sources following notification that Taiwan Semiconductor Manufacturing Company Limited (TSMC), its current sole supplier, will cease GaN production in July 2027.
• Navitas has partnered with Powerchip Semiconductor Manufacturing Corporation (PSMC) for GaN wafer production, with initial device qualification expected in Q4 2025.
• Mass production of 100V GaN products with Powerchip is anticipated in the first half of 2026.
• The transition of 650V GaN devices from TSMC to Powerchip is expected to occur over the next 12-24 months.
• Navitas is actively identifying and qualifying additional potential suppliers to further diversify its supply chain and enhance operational flexibility.
• The collaboration with Powerchip is expected to leverage Powerchip's 200mm in Fab 8B, which has been operational since 2019, and utilize an improved 180nm CMOS process for enhanced performance, power efficiency, integration, and cost.

Sentiment

Score: 7

Explanation: While the news of TSMC ceasing GaN production presents a significant supply chain challenge, Navitas' proactive and detailed plan to transition to Powerchip and diversify suppliers mitigates the negative impact. The new partnership is expected to bring technological and cost benefits, positioning the company for continued innovation and growth in key markets. The clear timelines and strategic rationale suggest a well-managed response to a critical event.

Positives

• Diversification of GaN wafer supply chain, reducing reliance on a single supplier (TSMC).
• Strategic partnership with Powerchip Semiconductor Manufacturing Corporation (PSMC) for 200mm GaN-on-silicon production.
• Powerchip's capabilities include an improved 180nm CMOS process, offering smaller and more advanced geometries, leading to improvements in performance, power efficiency, integration, and cost.
• Expected improvements in cost, scale, and manufacturing yields through 200mm GaN-on-silicon production on a 180nm process node.
• Powerchip will manufacture Navitas' GaN portfolio with voltage ratings from 100V to 650V, supporting growing market demands.
• The partnership is expected to drive sustained progress in product performance, technological evolution, and cost efficiency.

Negatives

• TSMC, the company's sole source of GaN wafers, will end GaN production in July 2027, necessitating a complete transition of supply.
• Potential risks associated with transitioning production of 650V GaN devices from an existing supplier (TSMC) to a new one (Powerchip) over a 12-24 month period.

Risks

• Reliance on a single supplier (TSMC) for GaN wafers until the transition to Powerchip and other potential suppliers is complete.
• Potential for delays or challenges in the qualification of initial devices with Powerchip (expected Q4 2025) or the commencement of mass production (expected 1H 2026 for 100V GaN products).
• Risks associated with the transition of 650V GaN devices from TSMC to Powerchip over the next 12-24 months, including potential supply disruptions or quality control issues during the ramp-up phase with the new supplier.
• General risks inherent in forward-looking statements, as actual events and circumstances may differ from assumptions and expectations.

Future Outlook

Navitas expects to qualify initial GaN devices with Powerchip in Q4 2025, with initial mass production of 100V GaN products anticipated in the first half of 2026. The company plans to transition its 650V GaN devices from TSMC to Powerchip over the next 12-24 months and is actively seeking to qualify additional suppliers to further diversify its supply chain.

Management Comments

• "Through our partnership with Powerchip, we are well-positioned to drive sustained progress in product performance, technological evolution, and cost efficiency." Gene Sheridan, CEO and co-founder of Navitas.
• "Powerchip has collaborated with Navitas on GaN-on-Si technology for years, and we're thrilled to announce that product qualification is nearly complete bringing us to the verge of mass production." Martin Chu, President and Director at Powerchip.
• "Building on this strong partnership, Powerchip is committed to expanding our cooperation and continuously supporting Navitas in exploring and growing the GaN market." Martin Chu, President and Director at Powerchip.
• "200mm GaN-on-silicon production on a 180nm process node enables us to continue innovating higher power density, faster, and more efficient devices while simultaneously improving cost, scale, and manufacturing yields." Dr. Sid Sundaresan, SVP of WBG Technology Platforms at Navitas.

Industry Context

This announcement highlights the ongoing evolution in the power semiconductor industry, particularly in gallium nitride (GaN) technology, which is crucial for high-efficiency power conversion. The increasing demand for GaN in emerging sectors like hyper-scale AI data centers (e.g., 48V infrastructure, 800V HVDC architectures), electric vehicles (EVs), solar energy systems, and home appliances underscores the strategic importance of a robust and diversified supply chain. Navitas' move to 200mm GaN-on-silicon production with advanced CMOS processes aligns with industry trends towards higher power density, improved efficiency, and cost reduction in power electronics.

Stakeholder Impact

• Shareholders: The announcement addresses a critical supply chain risk, potentially stabilizing future production and growth prospects. The strategic partnership with PSMC could lead to improved cost efficiencies and product performance, which may positively impact long-term shareholder value.
• Customers: Customers relying on Navitas' GaN products can expect a managed transition of supply, with potential for enhanced product performance and cost benefits from the new manufacturing process. The diversification aims to ensure continued supply.
• Suppliers: TSMC will cease being a supplier for GaN wafers by July 2027. Powerchip Semiconductor Manufacturing Corporation (PSMC) becomes a key strategic supplier, and other potential suppliers will be identified and qualified.
• Employees: The strategic shift in manufacturing partnerships ensures the continuity of the company's core business, potentially securing jobs and fostering innovation within the company.

Next Steps

• Qualification of initial GaN devices with Powerchip (expected Q4 2025).
