Chemical and Slurry Engineer

Role Overview:

The Chemical & Slurry Engineer will be responsible for design, operation, and reliability of process chemical and slurry delivery systems that support wafer fabrication. This includes bulk and specialty chemicals, CMP slurry blending/distribution, storage, and supply systems. The engineer will ensure continuous uptime, compliance with EH&S standards, and provide technical support for fab expansions and new tool installations.

Core Responsibilities:

Chemical & Slurry System Operations

• Operate and maintain bulk/specialty chemical delivery systems, slurry distribution units, mixing/blending stations, storage tanks, pumps, and valves.
• Ensure uninterrupted supply of acids, bases, solvents, and CMP slurries to wafer processing tools.
• Monitor system parameters (flow, pressure, purity, pH, particle stability) to maintain chemical and slurry quality.
• Implement preventive and predictive maintenance programs to ensure high uptime.

Engineering & Project Support

• Support installation, commissioning, and qualification of new chemical and slurry systems for fab expansion.
• Develop engineering documentation (P&IDs, equipment specifications, SOPs, MOC).
• Collaborate with tool hook-up teams to integrate process equipment with slurry and chemical supply systems.

Safety & Compliance

• Ensure compliance with SEMI, NFPA, FM Global, and local EHS regulations.
• Conduct risk assessments, HAZOP studies, and chemical hazard analyses.
• Implement safe handling, spill containment, and waste disposal practices for hazardous chemicals and slurries.

Reliability & Continuous Improvement

• Troubleshoot system issues related to contamination, flow restrictions, or slurry stability.
• Optimize slurry blending, filtration, and delivery processes to reduce cost and improve performance.
• Monitor KPIs (purity, uptime, chemical usage) and drive continuous improvement.

Collaboration & Leadership

• Partner with process engineering, EHS, and vendors to ensure system readiness.
• Provide technical training and guidance to technicians and operators.

Qualifications:

• Bachelor’s degree in Chemical Engineering, Materials Science, or related discipline.
• 3–10 years’ experience in chemical/slurry systems within semiconductor fab, chemical facility, or CMP operations.
• Strong knowledge of slurry blending, filtration, stability control, and chemical distribution systems.
• Hands-on experience with SCADA/DCS systems and process monitoring tools.
• Strong troubleshooting and analytical skills with root cause analysis experience.

Preferred:

• Experience in CMP (Chemical Mechanical Planarization) slurry systems.
• Familiarity with SEMI standards, ISO, and Process Safety Management (PSM).
• Vendor and contractor management for slurry/chemical system projects.
