Material Characterization Scientist

Job Title:

Material Characterization Scientist

Job Description:

Entegris is currently seeking a Polymer Characterization Scientist , CMP Pad to join our Materials Solutions Division R&D team. This position will be based at our Aurora (Greater Chicago Area) facility.

In this role, you will develop and advance fundamental understanding of the mechanical and rheological behavior of polymer systems used in CMP pad materials. You will lead the development of metrology capabilities and analytical frameworks that enable deep insight into structure–property relationships, supporting improved product design, consistency, and performance.

What You’ll Do Metrology & Method Development: Develop, optimize, and standardize mechanical testing methods (e.g., DMA, stress–strain, creep, oscillatory rheology) for CMP pad materials across development and manufacturing environments

Establish rheological characterization protocols (e.g., cure kinetics, viscoelastic behavior, frequency/temperature sweeps) to understand polymer network formation and processing sensitivity

Define and implement measurement best practices, calibration methods, and inter-lab correlation to ensure data consistency and reproducibility

Establish Structure– P roperty– P erformance Relationship: Correlate mechanical and rheological properties to CMP performance metrics

Build property-performance models to enable material design targets and process control windows

Support root-cause investigations for yield, consistency, and customer performance issues using quantitative metrology data

Data & M odeling : Working with scientist s and engineers in product design and production to d esign and execute DOE-based studies to isolate key variables affecting mechanical properties

Develop data analysis workflows and predictive models ; Establish databases and visualization tools to enable data-driven decision making across teams

Cross-functional and E xternal C ollaboration : Partner with formulation scientists, process engineers, and application teams to translate metrology insights into actionable products and process improvements guidance

Work with manufacturing teams to transfer lab-scale metrology into production-relevant measurements

Collaborate with instrument vendors and external partners to evaluate and deploy new characterization capabilities

Communication & T echnical L eadership Document and communicate findings through technical reports, standards, and presentations to internal and external stakeholders

Contribute to metrology strategy and roadmap, identifying gaps and future capability needs

Mentor team members on best practices in mechanical testing, rheology, and data interpretation

What We Seek PhD in Polymer Science, Materials Scienc e or related field required

3 + years of post-graduate industry experience in polymer structural characterization, mechanical testing and rheology ; Successful develop ed test methods, measurement systems, or analytical approaches

Hands-on experience with characterization techniques such as thermal-mechanical testing , rhe ometer , tensile and fatigue testing , and compression and flexural testing with demonstrated ability to design and troubleshoot experiments

Strong understanding of polymer mechanical and viscoelastic behavior, including structure–property relationships and the impact of network formation, crosslinking, and formulation on material performance

Practical experience in Design of Experiments (DOE), data analysis, and problem solving

Experience with thermoset, thermoplastic, elastomeric, or filled polymer systems is preferred

Knowledge of CMP or semiconductor processes is a plus, but not required

Self-motivated, collaborative, and able to operate effectively in a cross-functional, fast-paced environment

Strong communication skills with the ability to translate technical findings into practical recommendations
