Lead Scientist, Formulation

Entegris is currently seeking a Lead Scientist, Formulation to join our Formulated Solutions (FS) R&D group in the Technology & Innovation organization within our Materials Solutions (MS) Business. This position will be based in our facility. In this role, you will apply broad technical expertise and in-depth knowledge of CMP and pCMP mechanisms to solve complex customer and product-development challenges. You will lead critical project deliverables, define experimental strategies, and translate structure-performance relationships into differentiated products and process solutions.

Establish structure-property-performance relationships involving abrasive particles, oxidizers, inhibitors, complexing agents, polymers, surfactants, dispersants, and cleaning additives. Develop mechanistic understanding of material removal, selectivity, defectivity, corrosion, residue removal, particle removal, surface modification and formulation stability. Design and direct statistically robust experiments, including DOE and multivariate analysis, and integrate wafer, coupon, analytical, and formulation data to guide development decisions. Lead troubleshooting and root-cause analysis for complex slurry, cleaning, process, equipment, scale-up, and customer-performance issues.

Partner with Cleanroom Engineering teams to design and execute CMP and pCMP evaluations on relevant films, substrates, test wafers, and patterned wafers. Work with CSDs (Chief Solutions Designers) to put together technical packages for discussions with external customers during TRMs (Technical Review Meetings) Support raw-material selection, formulation robustness, scale-up, technology transfer, product qualification, and New Product Introduction. Drive intellectual property creation through filing of invention disclosures, patent filing support, detailed technical documentation, and protection of proprietary know-how via trade secrets.

Provide technical mentorship to scientists, engineers, and technicians and help establish best practices for experimental rigor, data quality, and laboratory execution. Build productive global networks and influence technical direction across teams without relying on direct authority. Maintain exemplary EHS, chemical-handling, quality, and documentation practices and actively strengthen a safety-first culture.

Travel up to 10%, including customer sites and global technology or manufacturing locations, based on business needs.

Ph.D. in Chemistry, Chemical Engineering, Materials Science, Polymer Science, Surface Science, or a related field with a minimum of 5+ years of relevant experience; OR a Master’s degree with a minimum of 7+ years of relevant experience; OR a Bachelor’s degree with a minimum of 9+ years of relevant experience; equivalent education and experience may be considered.

Demonstrated hands‑on experience in CMP slurry development, pCMP cleaning development, CMP process development, Wet Etch Formulations or closely related semiconductor surface‑processing technology. Thinking out of the box and being innovative to understand novel concepts in surface chemistry, colloid and interfacial science, particle behavior under polishing, chemical‑mechanical interactions, corrosion control, residue removal, and defect mechanisms;
All the while maintaining high standards of Safety & integrity. Working knowledge of Electrochemistry to identify influence of slurry / pCMP cleaning components in minimizing or eliminating corrosion on metal layers. Proficient with statistical analysis tools like JMP / Minitab to develop robust…
