How Chemical Delivery Systems Are Designed to Meet Facility Requirements

Different semiconductor manufacturing facilities or other users of chemicals have varying needs and specifications. That is why suppliers of chemical delivery systems need to able to customize their equipment to satisfy the specific requirements at different facilities. Suppliers who also manufacture their equipment in-house are better at adapting their standard products to meet the specific requirements of their clients, compared to third-party manufacturers.



The operation of chemical delivery systems can be divided into storage, delivery, and disposal functions. These functions are influenced by chemical volumes, the number of different chemicals, and facility layout. Operations that require a larger volume of chemicals, storage, and delivery options are different from smaller operations. Other determinants that also impact the execution of the chemical delivery system include the facility's space and equipment layout. A supplier needs to evaluate all these relevant factors and requirements before designing and building the custom system.



For example, a large operation requiring very few chemicals will only need few and simple controls. A different operation, which involves spiking with some chemicals and mixes others, will require complex controls with high precision. Requirements for repeatability, accuracy and quality control all come into the specifications for the design and configuration of the system. The system provided to a facility needs to incorporate each of these specific requirements.



Operator safety and system reliability are a paramount concern. However, the actual safety features required for the installation may still depend on the kind of chemicals used. Non-hazardous chemicals may not need any special safety measures, while hazardous and inflammable chemicals may require explosion-proof designs that must be certified safe by both the NEC and the NFPA.



In addition, operational strategies must be included to prevent workers from being exposed frequently to chemicals. For this reason, a degree of automation is required to enhance safety and reduce operation error. Semi-automatic and fully automatic systems usually have corresponding safety interlocks and automatic shut-down for dangerous conditions. In every case, the specific operating characteristics of the chemical delivery system must be evaluated and a custom solution needs to be designed and installed.
