This position requires strong process integration knowledge, hands‑on equipment experience, and the ability to analyze complex process interactions to drive performance improvements and technology development.

The successful candidate will play a key role in process development, equipment evaluation, technology transfer, and customer support activities within a fast-paced semiconductor R&D environment.

• Develop, optimize, and qualify new and existing semiconductor processes to meet customer and business objectives.
• Define process and equipment requirements for new technology development and product enhancements.
• Design, execute, and analyze experiments to evaluate process performance and identify improvement opportunities.
• Review and evaluate manufacturing and development techniques used in the fabrication and characterization of semiconductor devices.
• Coordinate process development activities with engineering, integration, and equipment teams to ensure compatibility between process requirements and hardware capabilities.
• Analyze experimental data and establish process windows, specifications, and control limits.
• Support the development and implementation of new equipment capabilities, automation strategies, and process technologies.
• Gather, assess, and communicate process development strategies to support future customer technology requirements.
• Provide technical leadership and support for process demonstrations and development activities at customer sites.
• Represent Kokusai in customer meetings to resolve equipment and process-related issues.
• Provide hands‑on troubleshooting and root cause analysis for process, hardware, and defectivity challenges.
• Review technical documentation and recommend improvements to operating procedures, specifications, and development plans.

• BS or MS in Materials Science, Physics, Chemistry, Chemical Engineering, Semiconductor Manufacturing, or a related technical discipline.

• Minimum 4 years of hands‑on experience with Kokusai semiconductor equipment platforms,
  or
• Minimum 6 years of hands‑on experience with 300 mm semiconductor process equipment from another OEM.
• At least 3 years of experience developing and optimizing one or more of the following technologies:
• LPCVD
• ALD / PEALD
• ALE / PEALE
• Thermal or plasma treatment processes
• Proven ability to independently lead technical discussions with customers and cross‑functional engineering teams.
• Demonstrated ability to manage process development activities with minimal supervision.

• Strong understanding of semiconductor process development, metrology, and defectivity analysis.
• Ability to create, modify, optimize, and troubleshoot advanced process recipes.
• Understanding of semiconductor material systems and their application to both process and hardware development, with an emphasis on CIP and new product opportunities.
• Experience analyzing data from commonly used metrology techniques for evaluating thin‑film physical, structural, and electrical properties.
• Ability to identify and troubleshoot process‑property relationships and hardware‑induced process variation.
• Experience investigating and resolving particle, contamination, and defectivity issues.
