Contamination Control Versatility

Simplify your operations and supply chain with a versatile contamination control strategy.


Integrated circuit manufacturing cycle time has never been more scrutinized. With an ongoing increase in fab utilization, the ability to save time is paramount to meet customer commitments. Process variations that were once absorbed into expected failure rates are now being examined more closely to find solutions to meet today’s yield goals. Contamination control is proven to have a positive impact on both your yield and equipment efficiency.

Liquid filters ensure chemical purity and maintain high wafer yields
. Filter reliability and efficiency are crucial considerations for your contamination control approach. Cleaner liquids equate to fewer defects caused by particles, gels, organics, and other materials, ensuring a reliable process. Filters, however, do not have an infinite lifetime and must be replaced at some frequency. Matching the right filter to your unit process, and choosing a filter that enables a long filter lifetime with a shorter flush-up time is the optimal solution to balance reliability and efficiency

Building upon the strong foundation of our Guardian® PS filters, Astera filters provide a versatile contamination control solution for aqueous chemistry unit processes. The novel Astera polyarylsulfone (PAS) membrane is designed for broad compatibility within dilute chemistries. The ability to utilize Astera filters across multiple applications simplifies your contamination control strategy by needing to hold fewer filters in stock.

Solid Precursors for 3D Architectures: Materials

Advanced 3D architectures for logic and memory devices increasingly rely on atomic layer deposition (ALD) to achieve high-quality, nanoscale conformal coatings. ALD deposits reactants and precursor molecules in alternating pulses to create the desired chemical makeup of the layers. Because of its ability to produce extremely thin films of uniform thickness and composition, ALD has supplanted physical vapor deposition (PVD) as the dominant deposition process for leading-edge technology nodes.

CMP Defect Control for Bulk Slurry Manufacturing

The purpose of a CMP process is simple – to planarize the top layer of oxide or metal with an abrasive slurry. Manufacturing the slurry to the exacting standards required by the end user is not easy. To effectively planarize the wafer surfaces, both large and small abrasive particles must be removed prior to being dispensed. Thus, the target is a narrow particle size distribution between 30 and 200 nm to prevent both microscratches and underlayer defects.
