Boise, ID (US). This is an on-site position, and we are not open to remote candidates at this time.

Responsibilities

• Own and optimize photomask cleans and resist strip processes in a cleanroom manufacturing environment.
• Monitor process performance, analyze SPC trends, and implement corrective actions to maintain process stability.
• Perform process characterization, troubleshooting, and root-cause analysis to improve yield, defectivity, and reliability.
• Support qualification of new tools, materials, recipes, and process changes.
• Develop and maintain process documentation, SOPs, control plans, and work instructions.
• Partner with equipment engineers to improve tool uptime, process capability, PM strategy, and excursion response.
• Collaborate with integration, inspection, metrology, pellicle, and manufacturing teams on cross-functional yield and quality issues.
• Support technology transfers, scale-up activity, and new product/process introductions.
• Ensure compliance with EHS, chemical handling, and cleanroom protocols.
• Drive root cause analysis and resolution of etch-related issues, reducing defects, variability, and production interruptions.
• Develop, optimize, and qualify etch processes using data-driven methodologies (DOE, SPC), ensuring stability and repeatability in production.
• Train and support technicians and junior engineers as needed.

Qualifications:

Knowledge, Skills & Abilities:

• Hands-on experience with lithography process development and troubleshooting in a cleanroom or manufacturing environment.

• Strong documentation, communication, and cross-functional collaboration skills.
• Ability to work effectively in a cleanroom and support production-driven schedules.
• Familiarity with Cleanroom operations.
• Familiarity with pellicle, inspection/repair, metrology, and other adjacent mask shop modules.

Experience:

• 3+ years of hands-on experience in semiconductor manufacturing, photolithography, photomask engineering.
• 3+ years of experience in semiconductor, photomask, or advanced microfabrication manufacturing, with direct experience in photolithography or patterning processes.
• Experience with tool qualification, process change control, and MES/fab automation systems.
• Experience supporting defect reduction and yield improvement in high-mix or high-volume manufacturing.
• Familiarity with Cleanroom operations.
• Familiarity with pellicle, inspection/repair, metrology, and other adjacent mask shop modules.

Education:

• Bachelor’s degree in Electrical Engineering, Materials Science, Physics, Chemical Engineering, or related field.
• A combination of relevant education and experience related to etch will be considered.

Travel: Less than 5%.
