Lead Scientist, CMP/pCMP

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.
