Liquid filtration primarily uses polymer membrane technologies as selective barriers that permit certain constituents in a fluid stream to pass through while retaining or rejecting others. A common misconception about membranes is that they are simply sieves that have one consistent pore in one barrier layer that retains all contaminants larger than the pore size. The selection of a membrane architecture is one critical factor in designing your unique contamination control solutions.

Nearly everything that goes into a fab – liquids, gases, and ambient air – has the potential to introduce contaminants that will impact performance. Each process area has a unique sensitivity to contaminants as well. It can be extremely difficult to remove targeted contaminants without disrupting the composition of semiconductor process materials.

A targeted removal model identifies each contamination threat, or threats, while maintaining the working balance of a material. When suppliers, equipment manufacturers, components makers, and fabs collaborate across the supply chain, they can create solutions that shorten yield ramps, limit maverick excursions, and improve device performance.

Not All Greenhouse Gases Are the Same
Biggest Benefits Come From Ranking Greenhouse Gas Reduction Impact

June 7, 2022

Semiconductor manufacturers face big challenges to reach their sustainability goals, and to reduce greenhouse gas emissions to the levels demanded both by legislation and by their customers. For scope 1 emissions capturing by-products and waste gases is extremely difficult, as process chemistry is highly diverse. Fab operators need to focus on the biggest contributors to climate change, and specifically on the common etch and clean gas,  NF3 , which is over 17,200 times more potent as a greenhouse gas than CO2. By using mass spectrometry to reduce the time spent on NF3-based clean cycles by up to 75%, operators can make big cuts in their NF3 emissions while also increasing throughput and reducing costs.

Fine particles (less than 5 micrometers in diameter) do not affect most industrial processes, but they can have a disastrous impact on semiconductor manufacturing. From the earliest days, manufacturing facilities have deployed air filtering and recirculation to remove particles from the cleanroom, but particles may still be generated inside process tools, where they can cause defects and yield loss. Quickly identifying when and where airborne particles originate can be challenging, but it is critical to success. Conventional methods for monitoring and diagnosing contamination problems take considerable time to return results, and, because of their intermittent nature, they may not see contamination episodes until the damage is detected by downstream inspections. In-line particle sensing (IPS) provides continuous, real-time monitoring, shortening response times and potentially limiting damage to work-in-progress.

However, several manufacturing processing hurdles need to be addressed to scale production to mass-market volume.

This white paper examines a new type of pressure-based mass flow controller (MFC) for semiconductor manufacturing that has been developed based on a combination of absolute and differential pressure transducers. The differential pressure sensor provides a direct measurement of pressure differential across a flow restricting device such as a laminar flow element. This eliminates a requirement to have matched discrete pressure sensors across a flow restrictor to calculate accurate pressure differential. Another design consideration is to locate the pressure sensors and flow restrictor upstream of the control valve to provide better immunity from downstream pressure fluctuations typically experienced in pulsed chemical vapor deposition applications, as well as achieve faster bleed down time of residual gases through the MFC. In addition, unlike conventional pressure-based MFCs, the differential pressure sensor-based MFCs can be operated at varying downstream pressure conditions- high vacuum and atmospheric pressures.
