What is Photoresist Filter?

A photoresist filter normally consists of several components, like filter media, housing, support, drainage, core, cage and end caps. And the common materials are usually PP, PES, PTFE, HDPE and more.

Made of various high performance polymers, Filson photoresist filters are specially designed to filter dots of photoresist, developers, etchant, etc. in photolithography process.

Owing to a lot of excellent properties, Filson photoresist filters are also widely used in a wide range of industries, such as electronic industry, semiconductor industry, pharmaceutical industry and so on.

Photoresist Filter Types by Filter Medias

Pleated Metal Photoresist Filter

Filson pleated metal photoresist filters are made of high quality stainless steel, like 304 and 316L. With dense metal mesh welded in pleated structure, they show large filtration area and low differential pressure, greatly enhancing filtration efficiency.

Sintered Metal Photoresist Filter

Featuring stainless steel powder sintered at high-temperature, Filson sintered metal photoresist filters provide high porosity and high contaminant loading capacity. Due to advanced welding technology, they ensure cleanliness and low particle shedding.

Nylon Photoresist Filter

Using naturally hydrophilic nylon membrane as filter media, Filson photoresist filters have spontaneous wettability and high flow rates. Therefore, they are ideal for bulk filtration of solvents, TMAH-based developers, photoresist and other nylon-compatible chemicals.

PP Photoresist Filter

Made of porous and multi-layer PP filter media, Filson PP photoresist filters show high dirt holding capacity and long service life. Based on these characteristics, they are suitable for filtration of suspended particles, colloids, high viscosity fluids and so on.

PES Photoresist Filter

Utilizing an asymmetric and hydrophilic PES membrane, Filson PES photoresist filters are designed for final filtration of photoresist production and filtration of lots of aqueous chemical solutions. They are also competent to provide high throughput, great particle retention, etc.

PTFE Photoresist Filter

Filson PTFE photoresist filters feature an all fluoro-polymer construction with pleated filter media, thus ensuring cleanliness and compatibility during filtration. Because of the excellent chemical resistance of PFTE, this kind of filter is ideal for filtration of aggressive process fluids.
