In-line Nanoparticle Monitoring System
Offering an Effective and Reliable Solution for sub-20 nm Liquid-borne Particle Monitoring
Chipmakers have been moving full speed ahead toward 5 nm products and beyond. The capabilities of the current particle monitoring technologies lag far behind the industry need. Currently, the semiconductor industry mainly relies on the well developed light scattering technology to monitor nanoparticles in production lines. However, it is also known that this technology has encountered its physical limit in measurement, and has been suffering from difficulties in consistent detections of particles smaller than 40 nm, not to mention those smaller than 20 nm. The inability to monitor and control nanoparticles in the processing wet chemicals has inevitably lead to the formation of killer defects on the wafers and resulting in serious product delays and yield losses. Thus, there are strong demands for in-line sub-20 nm particle monitoring for processing yield enhancement.
Innovative nanotech is a high-tech start-up, spun-off of ITRI and invested by Chroma ATE, dedicated to develop technology to "see" clearly, accurately and efficiently the size and distribution of the nanoparticles in the sub-20 nm range. Our product, SuperSizer®, is designed to work 24/7 in the strict semiconductor production environment. SuperSizer® enables the users to "see", and thus to control the "killer particles" before they result in "killer defects". Therefore, SuperSizer® has become the unprecedented yield enhancer in the nm range.
Clearly, this new tool has made significant break through over the current light scattering technologies. SuperSizer® is the state-of-the-art in-line ultrafine particle sizing system capable of accurately and reliably distinguishing particle size ranging from 3 nm to 1,000 nm with a concentration up to 1013/cm3. We believe SuperSizer® can and will enhance the processing yields of semiconductor fabrications to a new level.

Examples of Applications
Example of Suggested Points of Use
In semiconductor industry, slurries and chemical solutions are delivered from chemical delivery system (CDS) to fabrication tools. From drums (or lorries) to the points of use (POU), solution-type materials will pass through numerous pipes, valves, pumps, and even the filters. These pathways may pollute the solution if any part broken. SuperSizer®, focusing on the sub-20 nm contaminations, can work 24/7 to monitor these issue points, including raw material drums, point of supply (POS), point of delivery (POD), point of entry (POE), point of use (POU), and so on. This useful tool helps to improve the control of the cleanliness of the solutions, and further the fabrication yield.
