Researchers at Cornell University used a new imaging technique to see tiny imperfections inside computer chips. These flaws can affect chip performance and are crucial to understand.

Computer chips power devices like smartphones, cars, and AI data centers. But these chips have tiny imperfections that can slow them down or make them malfunction. A team of scientists at Cornell University has developed a new way to see these imperfections up close for the first time.

The researchers used high-resolution 3D imaging to study the atomic structure of computer chips. They found that even small defects can cause big problems. The team worked with Taiwan Semiconductor Manufacturing Company (TSMC) and Advanced Semiconductor Materials (ASM) to develop this new technique.

The findings were published in Nature Communications on February 23, 2026. Doctoral student Shake Karapetyan led the study. David Muller, a professor at Cornell University, said that this new imaging technique will be an important tool for debugging and fault-finding in computer chips.

Computer chips have become incredibly complex, with billions of tiny transistors working together. These transistors are like tiny pipes that control the flow of electrical current. Even small imperfections in these pipes can slow things down or cause problems.

The scientists studied how these imperfections affect chip performance and found that they can be a major issue. They hope that their new imaging technique will help manufacturers make better computer chips and improve device performance.

In the past, it was difficult to study these tiny imperfections because they are so small. The researchers used advanced electron microscopy techniques to get a closer look. This allowed them to see the atomic structure of the chip and identify defects that were previously invisible.

The team's leader, David Muller, has been studying the physical limits of semiconductor technology for many years. He worked at Bell Labs in the 1990s and early 2000s, where he helped develop new materials and techniques for making computer chips.

Muller said that the new imaging technique will be important for diagnosing performance issues in computer chips. He hopes that it will help manufacturers make better devices and improve device performance.

The study was published on February 23, 2026, in Nature Communications. The researchers used a combination of advanced electron microscopy techniques to get a closer look at the atomic structure of the chip.

The findings have important implications for the semiconductor industry. Manufacturers will need to use this new imaging technique to identify and fix defects in computer chips. This could lead to better device performance and improved reliability.
