R&D Process Engineer - Metrology

Overview

R&D Metrology Process Engineer - Semiconductor and Advanced Packaging

Overview:

The High Frequency Technology Center (HFTC) is seeking an R&D Metrology Process Engineer to develop measurement capabilities for 200 mm silicon interposer and advanced heterogeneous integration technologies. Our films and structures must perform at the leading edge of high-frequency electronics, making materials and dimensional metrology central to how the technology is developed. This is a hands-on fab role at Keysight Headquarters in Santa Rosa, CA.

Rather than specializing in a single tool set, you will build expertise across the full metrology stack: optical film modeling, CD-SEM, overlay, X-ray fluorescence, profilometry, electrical measurement, and virtual metrology, while helping select the fab's next generation of measurement capability. We welcome candidates with depth in one technique who want to extend that expertise across many. Strong measurement fundamentals are essential; prior expertise across every tool is not expected.  As the fab's dedicated metrology engineer, you will shape the metrology roadmap as the technology advances.

Responsibilities

• Own measurement recipe and method development across the fab's metrology platforms, including ellipsometry, reflectometry, CD-SEM, overlay, profilometry, X-ray fluorescence, and four-point probing.
• Develop and validate measurement methods and models for film properties, interfaces, critical dimensions, surface roughness, and topography that govern high-frequency electrical performance. Applications include multilayer optical modeling and CD-SEM measurements that require approaches beyond standard recipes.
• Develop virtual metrology models that use tool, process, and upstream measurement data to predict wafer results, reduce physical sampling, and extend coverage where direct measurement is impractical.
• Evaluate new measurement approaches and lead equipment selection, acquisition, and qualification with equipment teams and suppliers, including applications that existing capabilities cannot adequately address.
• Partner with design engineers to define and incorporate metrology structures into designs to enable reliable measurements.
• Establish measurement capability using reference standards, complementary techniques, GR&R, SPC, and DOE, and distinguish actual process variation from measurement artifacts, model limitations, calibration issues, and equipment behavior.
• Define sampling strategies that balance engineering information, measurement capability, throughput, and capacity.
• Document recipes, qualification criteria, and procedures so developed methods can be used reliably by others.
• Improve recipes that are not performing reliably, and provide occasional support when a critical lot cannot be measured correctly.

Qualifications

• B.S., M.S., or Ph.D. in Physics, Materials Science, Electrical Engineering, Chemical Engineering, Chemistry, or a related discipline. Relevant experience and demonstrated technical depth will be considered alongside education.
• 2+ years of hands-on experience developing or sustaining semiconductor processes or metrology in a cleanroom or fab. Recent graduates with extensive cleanroom and experimental backgrounds will also be considered, and experienced candidates will be considered for more senior levels.
• Strong understanding of the physical principles underlying at least one measurement technique, including how the measured signal relates to the reported result and what determines its accuracy, precision, sensitivity, and limitations.
• Demonstrated ability to develop or substantially modify measurement methods, models, or recipes, and to design experiments and investigate unexpected results.
• Ability to learn unfamiliar measurement techniques and build technical ownership across multiple platforms.
• Ability to communicate technical conclusions and limitations clearly and collaborate across engineering disciplines.

Preferred Qualifications:

• Advanced degree with substantial experimental work in measurement science, optics, thin films, or materials characterization.
• Experience with ellipsometry/reflectometry modeling, CD-SEM recipe development and signal interpretation, or characterization of surface roughness and buried interfaces.
• Experience developing virtual metrology, automated process control, or machine-learning models from process and equipment data.
• Experience with thin-film materials characterization relevant to RF or high-frequency electrical performance.
• Experience establishing reference standards, tool qualifications, or long-term stability monitoring, and transferring methods from development into production.
• Experience with JMP or equivalent; programming or scripting for data analysis and automation is a plus.

Candidates must be local or willing to relocate to Santa Rosa, CA
