About Stephen J. Buffat

As a Quality Manager, Staff Research Scientist, and Principal Process Development Engineer, I bring unique skills and experience in Semiconductor IC and Nanotechnology. Significant achievements in quality control, process characterization and development, applications, project, and R&D engineering, as well as management, mark my 30+-year career. I am skilled in all facets of quality control systems, ISO 9001, strategic planning, new business development, and project management in a global environment. My adeptness at external customer relationship building, supplier, and internal management for technology transfer and quality development is a testament to my strong interpersonal skills. Extensive experience coordinating and conducting operational and external site audits with material and equipment suppliers for process control and yield improvement and enhancement. I excel in defining, executing, and analyzing process design of experiments for process characterization, optimization, qualification, process and yield enhancement, and problem-solving. I have extensive experience in advanced coating development, coating chips to 300mm wafers with various advanced materials, including photoresists, polyimides, antireflective materials, adhesives, and carbon nanotube solutions, inks, and other nanomaterials. I am a published author of patents and peer-reviewed papers.

Experience

1. Quality Assurance Engineer

   Trillium Flow Technologies

   Oct 2024 — Present · Ipswich, MA, US

   I perform and oversee activities concerned with developing, applying, and maintaining quality standards for processing materials into finished products. When manufacturing or customer concerns arise, I analyze the problem and recommend corrective actions and solutions for continuous improvement. I review customer purchase orders, specifications, and engineering design documentation to determine customer requirements. I review and approve purchase orders and manufacturing orders. I participate in Material Review Boards, develop and initiate methods and procedures for inspection, testing, and evaluation. Additionally, I provide commercial-grade dedication, review, and acceptance of supplier quality procedures and certified material test reports to ensure compliance with ASME/CMS/ISO requirements.
