Plasma Control Technologies

In 2024, the semiconductor industry faced a dynamic landscape shaped by shifting demand patterns, supply chain adjustments, and ongoing technological advancements. Following the cyclical downturn in 2023, market conditions continued to gradually recover; however, the pace of improvement varied across different segments of the industry.

Demand for semiconductor components was largely fueled by the continued expansion of artificial intelligence (AI), cloud computing, and high-performance computing (HPC) applications. These technological catalysts drove significant market momentum, while other sectors experienced more restrained development. The persistent weakness in consumer electronics, particularly in smartphones and PCs, resulted in slower-than-expected growth for the semiconductor industry compared to initial projections at the beginning of last year.

In preparation for an anticipated increase in demand in 2025, PCT has taken key steps to enhance efficiency and optimize its manufacturing footprint. Lean management initiatives were being implemented, and high-volume manufacturing capabilities further developed, particularly for the Synertia® product range. A major capacity expansion will be achieved through the construction of a new facility in Penang, Malaysia, which is expected to be inaugurated in late 2026.

PCT also made significant progress in expanding its Synertia® RF Generator (RFG) product portfolio. Several RFGs have been successfully qualified for use in semiconductor equipment at key end customers. Additionally, the division has launched first platform projects integrating bundled Synertia® generators and matchboxes, incorporating the latest generation of PCT’s match technology. These developments mark a key milestone in enhancing the division’s RF power solutions. Furthermore, the expansion in Japan remains a strategic focus, particularly in growing the presence in RF power subsystems. This move aligns with the goal of driving long-term growth in key global regions.

Sales of the PCT division rose by 28.1% to CHF 247.4 million, from CHF 193.2 million in the prior year. Operating earnings at EBITDA level were 181.7% higher year-over-year at CHF 52.7 million (prior year: CHF 18.7 million). The EBITDA margin was thus 21.3% (prior year: 9.7%).
