DFS Slurry Blender and Distribution System with Transfer Unit

Posted by DFS on Sep 24, 2021 5:30:00 PM

Maximize Blend Accuracy and Production Uptime

This DFS system consists of a Slurry Blender and Distribution system, an external Transfer unit, and a Control Cabinet that controls all units. The Blender receives customer-supplied chemical from the Transfer unit or bulk feed system and facility UPW, performing a blend to tanks inside of the system. Each blend is weight-monitored and can be tracked with flow meters to ensure accuracy. The blends are validated by weight or optional conductivity and refractive index (RI) to qualify the batch before supplying to the facility fab. Distribution can be single loop, dual loop, or deadhead transfers, while blending can be completed using three user-selectable methods: batch, continuous batch, or continuous to the on-board distribution tank. Blends can be configured from the Recipe screen on the HMI, allowing blends to be adjusted to specified requirements.

Mobile Chemical Blending System Plus (Fusion™ MCBS+)

Posted by DFS on Jul 30, 2020 9:30:00 AM

DFS Fusion™ MCBS+

The DFS Fusion™ MCBS+ blends slurries or aqueous chemicals through our inline On-Demand™ blend technology or by weight and volume. All blending methods receive chemical from the customer-supplied chemical source, UPW, or on-board vessels.

Blends are prepared in either of the two 114L blend and dispense tanks, and each blend is verified through the blend specific on-board metrology set. The system maintains and supplies constant temperature and pressure control to the production area tools. Maglev pumps (one per tank) are used for the main chemical supply, and pneumatic pumps are used for blend recirculation and transfer from external vessels.

Fusion™ MCBS: A Closer Look

The DFS Fusion™ MCBS is a mobile chemical blending platform that can feed up to three production tools. The MCBS blends chemical by weight or by volume from externally connected source vessels, house ultrapure water (UPW), and optional house-supplied chemical.

Blends are verified through the on-board metrology in the blend tank and then transferred to the day tank maintaining constant temperature and pressure-controlled supply to the production areas. The MCBS uses a single centrifugal pump for the main chemical supply and pneumatic pumps for blend recirculation and transfer from the external vessels.

On-site Chemical Blending Increases Overall IC Process Yield, When Done Right.

Posted by Karl Urquhart on Jul 11, 2018 12:06:00 PM

Precise control of chemical composition through use of on-site chemical blending and mixing systems improves overall IC process yield. 

This is accomplished by providing more consistent quality of materials that come into contact with the wafer and its forming circuits. 

On-site blending results in tighter assay control, higher purity, and lower particles. On-site blenders also allow users to test materials suppliers for comparison to optimize ROI and control cost.

Mobile Chemical Blending Systems (MCBS) Help Overcome the Challenges of Next-Generation Chemicals

Posted by Karl Urquhart on Apr 12, 2018 2:10:49 PM

Uses and Benefits of Mobile Chemical Blending Systems (MCBS) 

A given factory's chemical formulations are pushed to: 1) improve affordability, while 2) requiring higher process performances in critical areas. One way to accomplish both goals is to target incoming chemical solutions that are high in concentrations and complexity.

Achieving the proper dilution and high performance in current and upcoming process nodes requires complex blends of organic and inorganic compounds in CMP slurry formulations. The combinations of all these factors result in products that have nuanced mixing and handling requirements.
