Sensor technology protects semiconductor industry from VOC exposure
10 January 2022
SEMICONDUCTORS ARE crucial pieces of technology that make Industry 4.0 possible. They require precise and careful fabrication, and the potential for exposure to VOCs (volatile organic compounds) during the process calls for the highest standard of sensors and monitoring – something ION Science can deliver.
Throughout the fabrication process, many different types of VOCs and gases are used in the creation of miniature integrated circuits on silicon wafers. It is critical that, during fabrication, the wafers are only exposed to the precise and desired amounts of VOC. Any unaccounted-for VOC, even at incredibly low levels, has the potential to interfere with the creation of the wafer and ruin the circuit. With demand for semiconductors at an all-time high, the risk of losing a batch of product due to improper monitoring is not something producers can afford to chance.
Employing the highest level of sensor monitoring in the semiconductor manufacturing facilities (known as fabs) is the best way to ensure product uniformity and to reduce the risk of defects from VOCs. Sensor monitoring in fabs has the added benefit of protecting workers, those who are working directly with the semiconductors and wafers, and local communities by monitoring and controlling off site emissions.
Worker risk is highest in cleanrooms, where a variety of chemicals are used throughout the stages of creating the wafers. Potential VOCs that workers could be exposed to include ethylene glycol, trichloroethylene and xylene, whilst as a result of certain processes, there is a risk of benzene and formaldehyde exposure. As all of these pose serious health risks, even in low concentrations, monitoring for VOCs and protecting the health of workers takes a high priority in the fabs.
Experienced in VOC monitoring and PID technology, ION Science have supported many semiconductor facilities in establishing appropriate monitoring technologies. ION Science’s leading range of MiniPID2 sensors , are renowned through the industry as the PID sensor of choice for monitoring and instrumentation. With a range of personal, portable and fixed instruments suitable for use in fabs, ION Science products can protect everything from individual workers through to whole sites and units.
For personal protection, the Cub range is designed for workers. Worn within the breathing zone for fast and accurate detection of VOCs, the Cub range weighs just 111g, making it lightweight and comfortable to wear while working. To keep sites safe, the Falco fixed detector provides superior sitewide monitoring, and is able to withstand harsh conditions and temperatures without condensing. All ION Science instruments utilise the leading PID sensor technology to guarantee the highest level of detection in all circumstances.
ION Science continues to support the semiconductor industry with a range of high-quality sensors and instrumentation that protect against VOC exposure. In a new and exclusive guide, ION Science discusses the role of VOCs in semiconductor fabrication, and how to better understand the processes and ways of protecting sites and workers.
