About this role
Job Title:
Lead Scientist, CMP/pCMP
Job Description:
The Role:
• Entegris is seeking a Lead Scientist with deep chemical mechanical planarization (CMP) and post-CMP cleaning (pCMP) experience to lead the development of advanced slurry and cleaning solutions for semiconductor applications.
• 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 technical workstreams, define experimental strategies, and translate structure-performance relationships into differentiated products and process solutions.
• The Lead Scientist will work across global R&D, Applications, Analytical, Manufacturing, Quality, Product Management, Marketing, and customer-facing teams. This position is an experienced technical leadership role and does not require direct people-management responsibility.
In this role you will:
• Technical Innovation & Product Development • Lead the formulation and process development of CMP slurries and pCMP cleaning chemistries for advanced semiconductor applications. • Define technical strategy, test plans, decision criteria, and development pathways for complex projects with significant technical ambiguity. • 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 contamination, surface condition, 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.
• Product Commercialization & Customer Success • Partner with Applications teams to design and execute CMP and pCMP evaluations on relevant films, substrates, test wafers, and patterned wafers. • Translate customer requirements and device/process trends into product specifications, technical milestones, and differentiated value propositions. • Lead technical reviews and communicate conclusions, risks, and recommendations to senior R&D leaders, cross-functional stakeholders, and customers. • Support raw-material selection, formulation robustness, scale-up, technology transfer, product qualification, and New Product Introduction. • Drive intellectual property creation through invention disclosures, patent support, technical documentation, and protection of proprietary know-how.
• Technical Leadership & Operational Excellence • 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 30%, including customer sites and global technology or manufacturing locations, based on business needs.
Traits we believe make a strong candidate:
• Ph.D. in Chemistry, Chemical Engineering, Materials Science, Polymer Science, Surface Science, or a related field with a minimum of 3 years of relevant experience; OR a Master’s degree with a minimum of 6 years of relevant experience; OR a Bachelor’s degree with a minimum of 8 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, or closely related semiconductor surface-processing technology.
• Deep understanding of CMP and pCMP fundamentals, including surface chemistry, colloid and interface science, particle behavior, chemical-mechanical interactions, corrosion control, residue removal, and defect mechanisms.
• Proven ability to independently solve complex, multi-variable technical problems and to determine appropriate methods, experiments, and decision criteria.
• Strong record of designing and analyzing statistically rigorous experiments and converting complex datasets into clear technical conclusions and next steps.
• Experience connecting formulation composition and process conditions to removal rate, selectivity, defects, surface quality, cleaning efficiency, and product robustness.
• Experience with semiconductor materials such as metals, dielectrics, barrier or liner films, and advanced interconnect materials is preferred.
• Experience supporting customer engagements, product qualification, scale-up, technology transfer, or commercialization is strongly preferred.
• Demonstrated technical leadership, influence, mentoring capability, and effective collaboration across global and cross-functional organizations.
• Excellent written and verbal communication skills, including the ability to present technically complex information in English to global teams and customers.
• Strong commitment to laboratory safety, data integrity, intellectual property protection, and disciplined technical documentation.
Your success will be measured by:
• Technical leadership: Establishes credible technical direction and resolves high-impact CMP and pCMP challenges through sound scientific judgment.
• Innovation and differentiation: Creates protectable formulations, mechanisms, methods, or product concepts that deliver meaningful customer value.
• Project impact: Delivers critical technical milestones, manages uncertainty and risk, and enables timely project decisions.
• Customer relevance: Connects customer process requirements to practical, robust, and differentiated material solutions.
• Collaboration and influence: Builds effective global partnerships and aligns cross-functional teams around evidence-based recommendations.
• Talent development: Raises team capability through mentoring, technical reviews, knowledge sharing, and rigorous experimental standards.
• Safety and quality: Demonstrates visible leadership in EHS, data integrity, documentation, and product-development discipline.
