How Optical Profilers are Used in the Semiconductor Industry

1. Surface Texture Characterisation and Measurement

Optical profilers are used to characterize and measure the surface texture of semiconductor components. This includes analyzing surface roughness, waviness, and other texture parameters that are critical for the functionality and reliability of semiconductor devices

2. Critical Dimension Measurement

They play a crucial role in measuring the critical dimensions of component structures in semiconductor manufacturing. This includes measurements such as post-CMP (Chemical Mechanical Planarization) die flatness inspection, bump height and coplanarity analysis, and defect identification, which are essential for ensuring the components meet design specifications

3. Process Optimization and Quality Control

By providing detailed surface topography information, optical profilers help in optimizing manufacturing processes and improving quality control. They enable the identification of defects and process-induced variations at early stages, thereby reducing waste and improving yield.

4. Research and Development

In the R&D phase, optical profilers are used to develop new semiconductor materials and processes. They provide valuable data that helps in understanding the effects of process parameters on surface properties, thereby aiding in the development of more efficient and reliable semiconductor devices.
