Filtering process elements is essential in the chemical industry because it helps maintain product sterility and quality by preventing particle and microbiological contamination. The product solutions from Brother Filtration assist safeguard the procedure against pollutants while prolonging product life and lowering operational costs.

The semiconductor industry has stringent requirements for highly specialized, high purity chemicals, gases and materials in the device manufacturing process.

In order to meet customer requirements for particle limits in microelectronic devices, electronic chemicals must be delivered to device manufacturers in very small amounts and tiny particles.

Electronics chemicals and materials

The microelectronics industry is particularly dependent on highly specialized, high-purity chemicals, gases and materials for device manufacturing. Electronic chemicals must be delivered to device manufacturers in very small quantities and tiny particles.

Filters are used to remove particles in a multi-stage filtration process, beginning with pre-filtration of raw materials and continuing through to final filtration in the final packaging step to meet customers’ stringent particle specifications.


Wet etching and cleaning

The wafer cleaning process removes particles that cause defects, as well as contamination from organic matter and metal ions. Photoresist removal requires the use of very aggressive, high-temperature acidic chemicals or strong organic solvent mixtures. Special acidic mixtures are used to precisely control the thickness of the dielectric layer to meet stringent specifications.

These very different processes require special attention to chemical and temperature compatibility, flow rates, and the ability to remove erosion and the high particle load that can result from the gel removal process when selecting the appropriate filter.

Chemical Distribution

Chemical and grind delivery systems are an efficient and safe way to deliver high volumes of chemicals and solvents to process equipment in a clean room.

These systems are fitted with cartridge filters of PFA, PP or even stainless steel for particle removal from drums or barrels to protect the chemical lines and the process being supplied.
