Engineer, Wet Etch Formulation

Job Title:

Job Description:

The Role:

• Entegris is seeking an Engineer I to support wet chemical formulation and process development for advanced semiconductor applications at the Korea Technology Center in Ansan.

• This entry-level role works within a global project team to execute laboratory experiments, analyze data, and support the development and integration of new wet etch and cleaning solutions that address customer process needs.

• The Engineer I will learn and apply established engineering and scientific methods under the guidance of experienced engineers and scientists, while building effective working relationships with colleagues in Korea and global technology centers.

In this role you will:

• Execute wet chemical formulation preparation, screening, and optimization experiments by following established procedures and project plans.

• Support semiconductor wet process evaluations, including coupon or wafer preparation, chemical treatment, basic process testing, and sample handling.

• Collect, organize, and analyze experimental data using standard tools; summarize results and identify observations that require further review.

• Maintain accurate laboratory notebooks, test records, chemical inventories, and technical documentation in accordance with quality and EHS requirements.
• Operate and maintain assigned laboratory equipment after completing required training, and promptly report equipment or process abnormalities.
• Collaborate with formulation scientists, application engineers, analytical teams, manufacturing, product management, and customer-facing teams to support project execution.

• Prepare clear technical summaries and presentations for project reviews; communicate progress, results, and issues to the project team.

• Support project milestones, sample preparation, technology transfer, and New Product Introduction activities as assigned.

• Contribute ideas for improving experimental efficiency, data quality, laboratory workflows, and product performance.

• Maintain a safe working environment and comply with all company safety, chemical-handling, and environmental procedures.

• Travel up to 10%, including visits to other technology centers, suppliers, or customer sites as business needs require.

• Support formulation scale-up and sampling activities, including preparation, labeling, documentation, and coordination of samples for internal evaluation and customer testing.

Traits we believe make a strong candidate:

• Bachelor’s degree in Chemical Engineering, Chemistry, Materials Science, mechanical Engineering or a closely related technical field.

• Entry-level candidate or recent graduate; prior industrial experience is not required. Relevant internship, undergraduate research, or laboratory project experience is preferred.

• Basic understanding of chemical engineering principles, wet chemistry, reaction kinetics, mass transfer, materials compatibility, or semiconductor processing.

• Hands-on laboratory experience with chemical solution preparation, experimental execution, safe chemical handling, and data recording.

• Ability to follow standard practices and procedures, analyze readily available data, and make recommendations based on defined guidelines and precedent.

• Strong attention to detail, problem-solving ability, learning agility, and accountability for assigned work.

• Ability to communicate and work effectively with immediate supervisors, project leaders, and cross-functional team members.

• Working-level English skills for technical documentation and communication with global teams.

• Basic proficiency in Microsoft Excel, PowerPoint, and Word; familiarity with statistical analysis or data-visualization tools is a plus.

• Ability and willingness to work a shift-based schedule as required to support laboratory operations, scale-up, and sampling activities.

Your success will be measured by:

• Safe and compliant execution: Consistently follows EHS, chemical-handling, laboratory, and documentation requirements.

• Technical execution and data quality: Completes assigned experiments accurately, on schedule, and with reliable, traceable data.

• Learning and problem solving: Builds wet chemical and semiconductor process knowledge and applies feedback to improve experimental work.

• Teamwork and communication: Collaborates effectively, communicates progress and issues clearly, and supports shared project goals.

• Accountability: Takes ownership of assigned tasks, follows through on commitments, and escalates risks or uncertainties promptly.

• Continuous improvement and creativity: Contributes practical ideas that improve product performance, test methods, or laboratory efficiency.
