Frequently Asked Questions
Optical filters and coatings designed for semiconductor manufacturing include high-precision wavelength filters, deep UV and infrared optical systems, and durable coatings for process control and inspection. These solutions enhance imaging, metrology, and real-time monitoring in fabrication environments.
Optical filters help isolate specific wavelength ranges that enhance contrast and signal fidelity during wafer inspection. By selecting the optimal spectral window, defects and overlay inaccuracies can be detected more reliably in imaging systems.
Deep UV (DUV) optics are critical for lithography and patterning, while infrared (IR) optics are essential for imaging and process monitoring tasks like etch endpoint detection. Combining these supports comprehensive control throughout fabrication.
Andover’s optics leverage precision wavelength control, advanced thin-film coatings, and vertically integrated manufacturing to provide highly stable and durable performance — essential for cleanroom conditions and multi-wavelength inspection systems.
Yes. Andover engineers custom optical coatings and filter assemblies optimized for specific semiconductor process tools, from photolithography systems to plasma process monitoring and high-speed imaging applications.
