Report Summary Catalogue Methodological

Semiconductor Inspection and Metrology Equipment refers to specialized tools used for quality control and performance testing of semiconductor products such as chips and wafers throughout the manufacturing and packaging processes. These tools cover the entire semiconductor value chain, from front-end wafer fabrication to back-end packaging and testing, ensuring the performance, reliability, and yield of semiconductor products.

Based on different process stages, semiconductor inspection can be classified into front-end inspection and metrology, back-end testing, and laboratory analysis. Front-end inspection is primarily applied during wafer processing and currently focuses on inline monitoring within the production lines. Back-end testing involves electrical and functional testing of processed chips, typically carried out through third-party testing services or inline monitoring. Laboratory analysis is used for defect localization and failure analysis of defective samples and is conducted either by third-party laboratories or in-house facilities.

For front-end processing and advanced packaging, inspection tools are subdivided into inspection and metrology based on their functional roles. These tools are essential for yield assurance throughout the chip manufacturing process. Defects generated during chip production directly affect final yield and increase manufacturing costs. According to Yole, with each successive node shrink, the number of critical defects generated in the process increases by 50%. As a result, each step in the manufacturing flow must maintain an extremely high yield rate to ensure an acceptable final yield. When the number of process steps exceeds 500, maintaining a per-step yield above 99.99% is necessary to achieve an overall yield above 95%. If the yield of a single process step drops to 99.98%, the final yield could fall to around 90%. This illustrates how the shrinking process window requires nearly “zero-defect” detection and metrology at every stage, making inspection and metrology indispensable to maintaining high yields in chip manufacturing.

Market Overview:

Key Development Trends

1. Capacity Expansion in Advanced Nodes and Advanced Packaging

Quality control in semiconductors is critical throughout the integrated circuit manufacturing process and plays a decisive role in determining chip yield. The development of AI has driven increased demand for computing and storage power, prompting regions such as mainland China to expand production capacity in advanced nodes and advanced packaging—further fueling growth in the semiconductor inspection and metrology market.

Advanced Process Nodes: According to our estimates, a 12-inch fab with a monthly production capacity of 10,000 wafers using advanced nodes requires 87 inspection and metrology tools—1.7 times the number needed for a mature node fab. The transition from FinFET to gate-all-around (GAA) architecture will lead to a 50% increase in critical layer inspection needs and a 30% increase in high-end thin-film metrology demand. Additionally, due to the resolution limits of optical inspection, electron beam-based metrology and inspection will see broader adoption as the process node advances below 10nm.

Advanced Packaging: AI GPUs and HBM (High Bandwidth Memory) increasingly adopt 2.5D/3D advanced packaging technologies. 2.5D packaging requires tools for RDL surface defect inspection, TSV profile metrology, and RDL critical dimension and height measurements. 3D packaging calls for equipment to inspect bond surface cleanliness, measure bond surface profiles, and assess wafer warpage. According to Camtek, the number of global chiplet packaging modules is expected to grow from 135 million units in 2024 to 457 million units by 2027, representing a CAGR of 36%, which will drive growth in demand for inspection and metrology equipment in advanced packaging.

2. Multi-System Integration May Become a Development Trend

With the continuous advancement of advanced process nodes, the complexity of IC materials and structures is increasing. Defects to be detected are shifting from surface-level to three-dimensional distributions, with increasingly complex geometries and dimensions approaching atomic scales. As a result, it is becoming increasingly difficult for single defect detection technologies to meet requirements. Multi-system integration is likely to become the trend in inspection technology development.

Pathway 1 – Traditional Optics:

Optical inspection technologies based on bright-field and dark-field illumination have been widely recognized by wafer fabs for their maturity, versatility, and reliability. However, due to the limitations of Rayleigh scattering, it is difficult to ensure high sensitivity at advanced nodes. Therefore, signal-to-noise ratio analysis for different defect types is particularly important.

Pathway 2 – Multi-Beam Electron Inspection:

Multi-beam electron imaging offers higher lateral resolution. However, its inspection speed still lags optical techniques by an order of magnitude. Research is focused on achieving a balance among system complexity, overall cost, and inspection efficiency.

Pathway 3 – Ultra-Short Wavelengths:

Techniques such as ptychographic diffraction imaging based on extreme ultraviolet (EUV) and hard X-ray wavelengths show promise for enabling 3D imaging of surface and subsurface defects on wafers. However, the lack of tabletop EUV and X-ray sources with high brightness, coherence, and stability remains a key bottleneck.

Pathway 4 – Structured Light Fields:

This approach aims to fully exploit the multidimensional intrinsic characteristics of light as a 3D electromagnetic field—beyond amplitude to include frequency, phase, polarization state, and orbital angular momentum—in order to maximize defect detection sensitivity.

3. Advanced Nodes Drive Increased Equipment Investment Demand

The value of inspection and metrology equipment per wafer is expected to multiply with advanced process development. AI chips demand higher performance, lower power consumption, and optimized cost, making advanced nodes particularly advantageous. As vehicle intelligence evolves, traditional chips like MCUs can no longer meet the market's needs. The increasing functionality of automotive chips is expected to accelerate the adoption of advanced manufacturing processes.

Currently, mainstream semiconductor nodes are evolving from 28nm and 14nm toward 10nm and 7nm, with some leading-edge manufacturers achieving volume production at 5nm and initiating R&D on 3nm. New technologies such as 3D FinFET transistors and 3D NAND are also becoming mainstream. These advances lead to an increase in process steps and microstructural complexity. To maximize wafer yield, future inspection/metrology tools will need improvements in sensitivity, accuracy, stability, and throughput.

As process nodes advance, the cost of equipment investment is expected to rise sharply. Advanced nodes will impose higher demands on process control, significantly increasing the value of inspection and metrology tools.

4. Electron Beam Inspection Supports Advanced Node Development

Electron beam inspection can significantly improve resolution. Accelerated electrons have wavelengths up to one ten-thousandth that of visible light, allowing electron beams to drastically enhance instrument resolution when used as illumination sources.

Electron microscopes, which use electron beams and electromagnetic lenses to form images and integrate mechanical, electronic, and high-vacuum technologies, include scanning electron microscopes (SEM), transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM), atomic force microscopes (AFM), analytical electron microscopes, and ultra-high-voltage electron microscopes.

Compared to optical inspection, electron beam inspection is slower and more expensive but provides higher precision. According to MMR, in 2022, applications below 1nm accounted for over half of the global electron beam inspection market. As IC process nodes shrink, defect sizes decrease, defect densities increase, and the risk of missed detections rises. Electron beam inspection offers significant resolution advantages and unique capabilities in identifying electrical defects.

From 2025 to 2033, the global electron beam inspection market is expected to grow rapidly, with applications above 10nm projected to become the main market for this technology by 2033.

5. Rapid Growth of the Chinese Market

SEMI projects that China will remain the world’s largest market for 300mm semiconductor equipment spending through 2027, with over USD 100 billion in investment expected over the next three years. This strong investment base positions the semiconductor equipment sector, a core component of China’s tech strategy, for substantial growth. Among the many segments, particular attention should be paid to those with low localization rates and high exposure to foreign export controls, such as lithography equipment, inspection and metrology tools, and front-end coater/developer systems.
