Automatic Chemical Delivery Module (CDM) and Chemical Delivery System (CDS) for Precise Point of Use Blending and Dilution
The Automatic Chemical Delivery Module (CDM) and Chemical Delivery System (CDS) form a high-precision network essential for modern semiconductor and photovoltaic fabrication. While the CDS focuses on the safe, bulk transport of chemicals from storage to the production floor, the CDM acts as the intelligent “point-of-use” processor. Together, they ensure that sensitive chemicals are delivered with parts-per-trillion (ppt) purity.
The standout feature of the CDM is its ability to perform precise blending and dilution automatically. In processes like Chemical Mechanical Planarization (CMP) or wet etching, chemicals often require exact mixing ratios to be effective. By utilizing PLC automation and non-contact sensors, the CDM eliminates human error, providing real-time adjustments to flow rates and concentrations. This level of control is vital for maintaining consistent wafer quality and high production yields in sub-micron manufacturing.
Constructed from 316L electropolished stainless steel with a 5Ra surface finish, both systems prevent particle shedding and contamination. Safety is integrated through nitrogen blanketing and secondary containment, protecting the facility from hazardous leaks. By combining automated blending with high-purity transport, these systems provide a seamless, fail-safe solution for the most demanding chemical distribution environments.
