BRS (Back-lapping slurry Recycle System)

1. Outline
BRS is a world-first recycling system for slurry waste created from the back-lapping process of the final assembly stage of semiconductors.
After consecutively collecting DI water and silicon from slurry waste, the silicon is refined to be re-usable as solar energy-related material.
With its specialized regeneration technology BRS, SILFINE is firmly rooted as an environment-friendly energy material corporation by providing cost reduction in scrap disposal and alternative solution to silicon production.
