DEVICE FOR APPLYING MAGNETIC FIELD TO A FILTER FOR REDUCING METALLIC CONTAMINANTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240375029 titled 'DEVICE FOR APPLYING MAGNETIC FIELD TO A FILTER FOR REDUCING METALLIC CONTAMINANTS
The patent application describes a filter used in microcircuit fabrication to remove metallic contaminants from a solvent.
- The filter housing includes a filter membrane to filter solvent with metallic contaminants.
- A magnet around the filter housing generates a magnetic field to attract metallic contaminants before they enter the filter membrane.
- The magnet is positioned to have a stronger magnetic field at the periphery of the filter housing compared to the central portion.
Potential Applications: - Microcircuit fabrication processes - Semiconductor manufacturing - Electronics industry
Problems Solved: - Removal of metallic contaminants from solvents used in microcircuit fabrication - Preventing metallic contaminants from reaching sensitive components
Benefits: - Improved quality of microcircuits - Enhanced reliability of electronic devices - Cost-effective solution for contaminant removal
Commercial Applications: - Filter systems for microcircuit fabrication facilities - Equipment for semiconductor manufacturing plants - Industrial filtration systems for electronics production
Questions about the technology: 1. How does the magnetic field attract metallic contaminants in the solvent? 2. What are the specific types of metallic contaminants that can be removed by this filter system?
Frequently Updated Research: - Ongoing studies on the efficiency of magnetic filtration in microcircuit fabrication processes.
Original Abstract Submitted
a filter is used for removing metallic contaminants in a solvent used in microcircuit fabrication. the filter includes a filter housing including a filter membrane for filtering solvent including metallic contaminants, and a magnet arranged about the filter housing and configured to generate a magnetic field to attract the metallic contaminants prior to the metallic contaminants entering the filter membrane. the magnet is arranged such that the magnetic field of the magnet is greater in a periphery of the filter housing compared to a central portion of the filter housing.
