Dustproof MEMS membranes bring many crucial advantages enabling better performance and reliability of MEMS components. The main advantages include high protection against dust and moisture ingress. These membranes have ePTFE material in their valuable structure that serves as a barrier that hits the fine particles up and allows sound waves to traverse through with some attenuation. Such a feature is important to keep the acoustic performance of microphones, particularly in dusty and wet environments.

It can also help to make your devices last longer. Dustproof MEMS membranes protect sensitive parts from dust/moisture, reducing wear and tear to extend the operational life of the microphones. Such durability is especially advantageous in situations where devices are exposed to an extreme environment like outdoors, or for functionality in industrial applications.

In addition, such dustproof MEMS membranes can be perfectly incorporated into the fabrication of MEMS devices. These membranes will also work for high-speed assembly processes without loss of the protection features. The integration of the transistor design with other components in an IC reduces the manufacturing complexity and confirms that it can meet performance specs.
