Nowadays, silicon wafers are a key input for the world’s most advanced technologies, offering the groundwork where chip components are built. Telephones, cars, medical devices, and all of our technology depend on these small circuits today, which is why ensuring the surface of a semiconductor is perfect during wafer manufacturing.
Among quality control practices, surface inspection is a must. New methods, such as Atomic Force Microscopy (AFM), are being incorporated as innovation expands in the semiconductor industry. These can potentially change the wafer manufacturing industry, and here we’ll explain why.

As the components of integrated circuits become smaller—and their complexity bigger—ensuring the reliability of silicon wafers is key. Surface inspection plays a big role in this.
Surface inspection allows the identification of defects on wafer surfaces, including scratches, particles, pits, and other irregularities. These flaws may result from crystal growth, wafer slicing, chemical processing, or other manufacturing steps.
Surface quality directly impacts semiconductor devices' electrical performance, and even minor imperfections can lead to significant issues in downstream processes. Early detection is crucial to prevent this.
The Atomic Force Microscope (AFM) is a precise metrology tool and a scientific research instrument with exceptionally high resolution.
The AFM uses a system to detect the minuscule variations between the surface being studied and the atomically sharp silicon probe. It can track and quantify surface details at the nanoscale—in fact, optical systems can detect features of interest as close as one micrometer.
For that reason, AFM is a vital tool in wafer surface inspection within the semiconductor manufacturing process. It is especially well-suited for evaluating the quality of silicon wafers and other materials used in microelectronics because of its high-resolution imaging capabilities and capacity to analyze surface properties.
