Plan Details
Based on its independently developed ePTFE (expanded polytetrafluoroethylene) microporous membrane technology, Voir Semiconductor offers a comprehensive, high-purity, high-precision microfiltration solution for the semiconductor manufacturing sector. Adopting a “self-developed materials + full-chain production” model, this solution addresses the stringent requirements for controlling nanoscale particulates and ionic contamination in critical processes such as wet etching, CMP, and cleaning, providing a range of ultra-clean, chemically compatible filtration products and components to help improve chip yield and performance.
| Core Technology
Voir’s microfiltration solution is built on its proprietary ePTFE microporous membrane technology and boasts several core advantages:
· Excellent material properties ePTFE material exhibits inherent chemical inertness, excellent thermal stability, and high mechanical strength, enabling it to withstand high temperatures and highly corrosive chemical environments, thereby ensuring the stability and safety of the filtration process.
· Gradient Pore Structure It employs a three-dimensional stacking and gradient pore-size structure, enabling staged deep filtration. While maintaining a high retention rate, it also delivers a higher flow rate, resulting in greater dirt-holding capacity and an extended service life.
· Fully in-house developed across the entire value chain : Voir boasts a complete technological chain, spanning ePTFE microporous material technology to filter cartridge folding, integrated assembly, and cleaning processes. It has established a dedicated semiconductor filtration membrane production line and independently develops its own hydrophilic/hydrophobic filtration membranes, thus avoiding supply-chain challenges.
· High cleanliness assurance : The stringent cleaning process ensures that the perfluorinated filter exhibits extremely low ion leaching, while hydrophilic or hydrophobic filtration media can be customized to suit various application scenarios based on customer requirements.
