On June 2, 2026, Infineon Technologies AG, a global leader in power semiconductors, officially announced that it would gradually transfer the back-end manufacturing operations of its Tijuana, Mexico facility to other production sites. Concurrently, the company disclosed that it is evaluating future disposition options for the plant, including a potential sale.

This decision follows a prior strategic move in February 2026, when Infineon reached an agreement with U.S. foundry SkyWater to sell its 8-inch Austin, Texas wafer fab (Fab25), accompanied by a long-term supply agreement.

The Tijuana Facility

The Tijuana plant traces its origins to 1973, when it was established by International Rectifier. Following Infineon's acquisition of International Rectifier in 2015, the facility was integrated into the Infineon group.

The plant primarily engages in back-end manufacturing, encompassing wafer sawing, chip assembly, and final testing. Additionally, it houses Infineon's IT service center and human resources service center, performing certain group-level functional support roles. The facility currently employs several hundred workers.

Geographically, Infineon operates four plants across the Americas: three in the United States (front-end fabs in Austin and Mesa, plus the back-end facility in Tijuana) and one back-end plant in Leominster, Mexico.

Strategic Rationale

George Lee, Head of Infineon's Back-End Operations, stated in an official release: "The realignment of manufacturing activities at our Tijuana site supports our ongoing efforts to optimize our global manufacturing footprint and will contribute to enhancing overall scalability and long-term competitiveness."

From an industry perspective, this transfer is driven by multiple factors. On one hand, Infineon's manufacturing strategy is built upon a hybrid model of in-house production and strategic outsourcing, emphasizing high productivity and cost competitiveness. Shifting back-end capacity toward centralized bases with greater economies of scale can reduce unit production costs and improve resource utilization efficiency.

On the other hand, global capacity rebalancing plays a significant role. Infineon is currently constructing a new back-end production base in Samut Prakan, south of Bangkok, Thailand. Simultaneously, the company is advancing its China localization strategy, transferring manufacturing of certain commodity-grade products to Chinese contract manufacturers.

Impact of the Production Transfer

Infineon emphasized that the production transfer will be carried out in phases over the coming years, with no interruption to product deliveries. Employees, customers, and suppliers will not face immediate changes in the short term.

For the local community in Mexico, a potential sale of the Tijuana facility would involve the reallocation of several hundred employees. Infineon stated it will "manage the transition carefully and explore various options for the future use of the site, including a potential sale, to create prospects for the local community and our colleagues."
