Field Process Engineer

About the Role

As a member of the Global Sales and Services business unit, the HVM (High Volume Manufacturing) Field Process Engineering team serves as the on-site technical bridge between customers, ASM Field Service, account leadership, and global product teams. This role supports ASM Synergis and Pulsar thermal ALD deposition systems at a customer fab in North Phoenix. The position involves working closely with the customer and internal teams to support process performance, equipment qualification, tool-to-tool matching, troubleshooting, and continuous improvement in a high-volume semiconductor manufacturing environment. This is an opportunity for an early-career engineer seeking hands-on experience with thermal ALD, thin-film deposition, semiconductor processing, and advanced semiconductor equipment.

Key Responsibilities

• Support ASM Synergis and Pulsar thermal ALD systems through installation, start-up, qualification, HVM ramp, and production-support activities.
• Monitor process performance, tool-to-tool matching, process stability, and customer specifications through structured data review and follow-up.
• Support troubleshooting and resolution of process and equipment-related issues in partnership with Field Service Engineers, customer engineers, and global technical teams.
• Assist with experiments and data analysis for process qualification, troubleshooting, continuous improvement, and process-window optimization.
• Collect and analyze process, metrology, tool-state, and chamber-performance data to support technical decision-making.
• Apply structured problem-solving techniques, DOE, SPC, baseline comparisons, and statistical analysis to understand process behavior.
• Support analysis of thin-film characteristics including thickness, uniformity, particles/defects, composition, and other relevant process outputs.
• Clearly communicate technical findings, actions, risks, and next steps to customers and internal stakeholders.
• Document issue timelines, experimental results, troubleshooting activities, action plans, and lessons learned.
• Support critical customer needs and escalations while maintaining strong discipline around safety, controlled changes, confidentiality, and customer/ASM intellectual property.

Requirements & Tech Stack

• Ability to analyze experimental and process data using tools such as JMP, Python, MATLAB, Excel, or similar analytical tools.
• Ability to work on-site in a customer semiconductor fab and cleanroom environment in North Phoenix.
• Flexibility to support extended hours or weekends when required for qualifications, escalations, or critical customer needs.
• Ability to travel as needed for training or technical support.

Qualifications

• Bachelor's or Master's degree in Chemical Engineering, Materials Science, Chemistry, Electrical Engineering, Mechanical Engineering, Physics, or a closely related technical discipline.
• Academic, research, internship, or industry exposure to thermal ALD, thin-film deposition, semiconductor processing, surface chemistry, reaction kinetics, vacuum systems, gases/pressure/flow, or related technologies.
• Strong technical fundamentals and ability to learn complex semiconductor processes and equipment.
• Strong English communication skills and the ability to communicate effectively with customers and cross-functional teams.
• Strong ownership, accountability, organization, and attention to detail.
• Ability to remain structured and communicate clearly while working through urgent or incomplete technical information.

What Sets You Apart

• Hands-on academic, internship, research, or industry experience with thermal ALD or thin-film deposition.
• Familiarity with ALD fundamentals, including precursor chemistry, surface reactions, temperature effects, film growth, uniformity, and process optimization.
• Experience with semiconductor equipment manufacturers, OEM suppliers, or semiconductor manufacturing environments.
• Experience with DOE, SPC, statistical analysis, metrology, or characterization of thin films.
• Previous cleanroom, fab, laboratory, or semiconductor equipment experience.
• Strong customer-facing mindset and ability to collaborate effectively across technical teams and cultures.
• Mandarin proficiency is a plus, but not required.
