MS® PTFE Filtration for Microelectronics Description

MS® PTFE membrane with the ability to repel water-based fluids (hydrophobic),can be used in many fields ,especially in microelectronics and semiconductor.This membrane can protect the devices from the external contaminant,such as water vapor, volatile organics, acid gases and so on.

Contamination Control for Micro-Electronics and Semiconductor

There are many forms of contamination in the environment that can reduce the reliability of microelectronics and semiconductor. Control strategies are summarized below. 

Contaminant Effect Control Strategies
Particles ●Signal degradation ●High efficiency Membrane
●Short Circuit
Oils ●Signal degradation ●Oleophobic Membrane
●Short Circuit
Liquid Water ●Corrosion ●Hydrophobic Membrane
●Short Circuit
