The semiconductor industry is in the middle of a transformative era as it collides against the physical limitations of rapid and more efficient microchip. As we progress to the “Angstrom era”, where chip features are measured only in atoms, the challenges of manufacturing have reached unprecedented levels. Today’s most advanced chips, such as 2Nm nodes and beyond, are demanding innovations not only in the design but also in the devices and processes used to create them.
This challenge has a complexity to detect defects in the heart. In the past, optical inspection techniques were sufficient to identify and analyze defects in chip construction. However, since chip features have been continued and the device has developed from the Architecture 2D planner transistor to 3D finfet and gate-all-round (GAA) transistors, the nature of the defects has changed.
Defects are often so small in scales that traditional methods struggle to find them. Now not only surface-level flaws, they are now usually deeply buried within complex 3D structures. The result is an exponential increase in the data generated by inspection devices, in which the defect maps become dense and more complex. In some cases, the number of conviction candidates required to be reviewed has increased by 100 times, existing systems have been overshadowed and hurdles have arisen in high-vigor production.
The CFE technology of applied materials achieve sub-nanometers resolution, which is capable of detecting deep burial defects within the 3D device structures.
The burden created by increasing data is complex with the requirement of high precision. In the Angstrom era, even the smallest defect – a zero, residue, or particle can only compromise a few atoms wide – chip performance and yield of chip construction process. Separating true defects from false alarms, or “nuisance defects”, has become rapidly difficult.
Traditional defect review systems, while in their time are struggling to keep pace with the demands of effective, modern chip construction. The industry is at a divine point, where the ability to detect, classify and analyze defects is not just a competitive advantage now – this is a need.

Adding the complexity of this process is a change towards more advanced chip architecture. The 2Nm node and beyond it requires logic chips in high-gradation drama and 3D nand memories, which require dosha review systems capable of navigating 3D structures and identifying issues in Nanoskel. These architecture is necessary to strengthen the next generation of technologies from artificial intelligence to autonomous vehicles. But they also demand a new level of accuracy and speed in detecting the defect.
In response to these challenges, the semiconductor industry rapidly and more accurate defects are looking at increasing demand for review systems. In particular, high-volume manufacturing requires solutions that can analyze more samples rapidly without renouncing sensitivity or resolution. By combining advanced imaging techniques with AI-operated analytics, the next generation defect review system is able to separate the signal from the noise and intensify the path from development to production.
Ebeam evolution: future driving of defect detects
Electron beam (EBEAM) imaging is a long-standing semiconductor manufacturing, which provides ultra-high resolution required to analyze the defects invisible for optical techniques. Unlike light, which has a limited resolution due to wavelength, electron beams can achieve resolution on the sub-nanometer scale, making them indispensable to investigate the most small flaws in modern chips.
Applied material
EBEAM technology trip has been one of the continuous innovations. The early systems were dependent on the thermal field emission (TFE), which produces an electron beam by heating a filament to a very high temperature. While TFE systems are effective, they have limitations. The beam is relatively broad, and high operating temperature can cause volatility and low lifetime. These obstacles became rapidly problematic as the chip facilities shrink and the requirements to detect the defect became more rigid.
Enter the Cold Field Emission (CFE) technology, a success that has redefined the capabilities of the EBEAM system. Unlike Tfe, CFE operates at room temperature, using a sharp, cold filament tip to emit electrons. It produces a narrow, more stable beam with high density of electrons, resulting in considerable improvement resolution and imaging speed.
Applied material
For decades, the CFE systems were limited to the use of the labs as it was not possible to keep the equipment up and run for enough time – mainly because at “cold” temperatures, the contaminants inside the chambers follow the eBEAM emitter inside the chambers and partially block the flow of electrons.
In December 2022, Applied material Announced that it had solved credibility issues with the introduction of its first two ebeam systems based on CFE technology. At the forefront of detecting applied defects, the leader of the industry is at the forefront. It is a company that has consistently pushed the boundaries of material engineering to enable the next wave of innovation in chip construction. After more than 10 years of research in a global team of engineers, the CFE stability reduced the challenge by developing several successes. These include new technology for ordering high vacuum compared to TFE-stitching ebeam columns with special materials that reduce contamination, and a novel room designs self-cleaning process that keeps the tip clean.
The CFE technology acquires sub-nanometer resolution, able to detect deep burial defects within the 3D device structures. It is a capacity that is important for advanced architecture such as gate-all-round (GAA) transistors and 3D Nand Memory. Additionally, CFE systems provide rapid imaging speeds compared to traditional TFE systems, allowing chipmakers to analyze more defects in less time.
AI’s rise in semiconductor manufacturing
While the EBEAM technique provides the foundation to detect high-resolution defects, the sheer volume of data generated by modern inspection equipment has created a new challenge: how to process and analyze this data quickly and accurately. This is the place where artificial intelligence (AI) comes in the game.
AI-driven system can classify the defects with remarkable accuracy, sorting them into categories that provide actionable insight to engineers.
AI is changing manufacturing processes in industries, and semiconductors are no exception. AI algorithms – particularly based on deep education – are being used to automate and enhance the analysis of defect inspection data. These algorithms can squeeze through dataset on a large scale, identifying patterns and anomalies that would be impossible for human engineers to manually detect.
By training with real in-line data, AI models can learn to differentiate between true defects-such as voids, residues and particle-and false alarm, or “fuss defects.” This capacity is particularly important in the Angstrom era, where the density of the blame candidates has increased rapidly.

In high-vantage manufacturing, where small improvements in yield can also translate into significant cost savings, AI is becoming unavoidable.
The infection for advanced nodes, the rise of complex 3D architecture, and exponential increase in data have created an ideal storm of manufacturing challenges, seeking a new approach to reviews. These challenges are being fulfilled with the new applied new Semavisan h20,

The semvision H20 makes the inheritance of the EBEAM system of the H20 applied, which is the standard of gold to review the defect for a long time. This second generation CFE has more sub-nanometers resolution faster than both TFE and first generation CFE, as the electron flow has increased through its filament tip. These innovative abilities enable chipmeckers to identify and analyze the smallest defects and buried defects within 3D structures. At this stage accuracy is essential for emerging chip architecture, where the imperfection of the most young can also compromise and yield.
But the capabilities of Semavisan H20 go beyond imaging. Its deep learning AI model is trained with real in-line customer data, enabling the system to automatically classify defects with remarkable accuracy. By separating true defects from false alarms, the system process reduces the burden on control engineers and intensifies the defect review process. The result is a system that provides 3x rapid throopoot while maintaining the highest sensitivity and resolution of the industry – a combination that is changing high -martial manufacturing.
Extensive implication for industry
