Market Dynamics
Rising semiconductor advanced node demand and solar cell manufacturing are driving thin film metrology growth.
The manufacturing of advanced semiconductors at 3nm and smaller requires atomic-level precision for both thin film deposition and measurement processes which creates continuous demand for advanced metrology systems. Tool orders at leading-edge fabs are primarily driven by two requirements which include stack-height control for 3D NAND and conformality checks for atomic-layer-deposited films. The global solar energy expansion currently generates ongoing demand for photovoltaic cell metrology services. In 2024, global renewable energy capacity experienced its highest growth rate of 15.1% which means that every new solar manufacturing line must install precise thin film measurement systems to improve cell efficiency throughout the photovoltaic layer deposition processes.
High system costs and complexity of multi-layer measurement restrain thin film metrology market expansion.
Advanced metrology solutions for thin films, especially when combining ellipsometry with X-ray technology, incur significant upfront costs. This is because of their applicability in highly sophisticated semiconductor structures comprising multiple layers. For small semiconductor manufacturers and consumers from developing markets, the cost benefit of such tools does not work out well, thus limiting the reach of the market. Another factor complicating the adoption of advanced multi-layer metrology solutions is their technical configuration and validation, which takes time and requires specialized skills, which are difficult to come by owing to the shortage of semiconductor engineers worldwide.
Advanced semiconductor node qualification and photovoltaic cell efficiency demands offer strong metrology opportunities globally.
Under the CHIPS Act, USD 52 billion is provided to support research and development in U.S. semiconductors, and among the requirements of such projects is the provision of advanced metrology infrastructure in all the new facilities created under the initiative. Likewise, under the Horizon Europe initiative by the EU, investments will be made into research into semiconductors that need to rely on precision measurement infrastructures. Apart from semiconductors, next generation photovoltaic cell designs such as perovskite and tandem cells also need multi-layer optical analysis at high precision measurements that existing reflectometry cannot provide.
Measurement accuracy at sub-nanometre scales and rapid technology evolution challenge thin film metrology participants.
The current measurement systems at gate-all-around and nanosheet transistor scales have reached their optical metrology boundaries which need new measurement methods instead of bettering current measurement systems. X-ray metrology developments enable measurement of dimensions which optical methods cannot detect but the implementation of X-ray systems introduces additional expenses and operational difficulties. The speed at which semiconductor node development progresses now creates customer needs which metrology system development times cannot fulfill. The 2024 increase in AI-assisted defect classification patent applications shows that software advancements now drive competitive advantages between next-generation metrology systems more than hardware progress.
AI-integrated metrology, in-line measurement adoption, and EUV process control reshape thin film metrology trends.
The incorporation of AI into thin film metrology solutions has led to a 20% reduction in recipe configuration times as well as an enhanced capability for adaptive measurements which can adjust in line with process drifts. In-line metrology solutions which have been integrated directly into deposition equipment suites have taken over from offline metrology stations in advanced fabs, lowering the delay in process feedback time from hours to minutes. At the same time, the deployment of extreme ultraviolet (EUV) lithography technologies in advanced nodes is also generating demand for new thin film metrology solutions for characterizing EUV pellicle layers and EUV anti-reflective coatings.
