Overview
JASCO is headquartered in Hachioji, Tokyo and designs and builds spectroscopy instruments in Japan. Its main products are Fourier-transform infrared (FTIR) spectrometers, Raman spectrometers and UV-visible spectrophotometers.
In semiconductor work these instruments are used to check film composition and stress, and to identify organic residues that electrical tests cannot reveal.
Business: Spectroscopy instruments: FTIR, Raman and UV-visible
Why it matters
- Raman spectroscopy can measure stress and crystallinity in silicon and compound semiconductor layers without contact.
- FTIR identifies organic contaminants by their chemical bonds, which helps trace the source of a defect.
Main products
- •FTIR spectrometers
- •Raman spectrometers
