OverviewA compact, ultra-clean point-of-use (POU) filtration system designed to remove particles from Ultra Pure Water (UPW) supplying critical wet/clean tools in semiconductor fabrication.
Detailed descriptionSemiconductor manufacturing requirements have outpaced conventional particle metrology and final filtration used in UPW systems. Conventional final filters have pore sizes close to, or larger than, the critical sizes that generate so-called "killer" defects. As device geometries approach 10 nm and smaller, controlling particles at the point of use is essential.
Components and non-steady-state conditions across a UPW distribution loop—piping, valves and transient events—can generate or release particles that contaminate tools. The VANOX® POU‑F System mitigates this risk by applying validated materials and point-of-use particle-removal technology to minimize particle transfer to critical tools.
Leveraging over a decade of Vanox deployments in immersion lithography, the POU‑F adapts that particle-control technology for broader fab use. The system integrates with Evoqua's Microelectronics Technology Suite to provide real-time monitoring and data-driven operation.
