Air Products and Chemicals, Inc.ulk Chemical Delivery (BCD) System is stainless steel and compatible with electronic chemicals used in chemical vapor deposition processes (CVD).

Using a direct digital control interface to communicate with a wide variety of process tools, the system features stainless steel piping and large flow capacity suitable for the requirements of high-purity, high-volume fab-wide chemical supply. An ultrasonic empty sensor allows 99.99% of the bulk chemical to be used, while a microprocessor-based controller monitors the removal of all chemical from the container connections.

The system's cabinet design reduced exhaust requirements by 75% and maximizes the use of floorspace in the fab by incorporating a small footprint and minimal clearance requirements.
