FabSight wants to watch copper plating in progress
FabSight is developing optical metrology and AI-assisted analysis for semiconductor electrodeposition, starting with copper feature filling on patterned test chips.
- For
- Semiconductor process-development and plating-chemistry teams
- Worth noticing
- The initial scope is copper feature filling on patterned test chips; the Alpha-1 instrument is still under development.
Field notes
The proposed workflow links image sequences to electrochemical conditions, then applies multivariate analysis, clustering, and machine-learning methods to compare responses across patterned regions. Named early applications include damascene interconnects, through-silicon vias, and plating-chemistry development. The site says the team is working on prototype design and integration, with controlled copper-deposition studies and validation still ahead.
