Internship, Process Engineer, Terafab (Winter/Spring 2027)

What to Expect

Consider before submitting an application:

This position is expected to start January 2027 and continue through Spring term (ending approximately May 2027) or continuing into Summer 2027 if available and there is an opportunity to do so. We ask for a minimum of 12 weeks, full-time (40 hours/week) and on-site, for most internships. Our internship program is for students who are actively enrolled in an academic program. Recent graduates seeking employment after graduation and not returning to school should apply for full-time positions, not internships.

International Students: If your work authorization is through CPT, please consult your school on your ability to work 40 hours per week before applying. You must be able to work 40 hours per week on-site. Many students will be limited to part-time during the academic year.

Terafab is building a vertically integrated semiconductor factory at an unprecedented scale. The facility brings logic, memory, packaging, test, and lithography mask production under one roof, optimized for rapid iteration and maximum compute density per square foot.

Process engineering is the discipline that turns Terafab technology into reality, atom by atom. This role owns ion implantation processes across three distinct chip families: edge-inference processors, space-hardened data center AI chips for orbital satellites, and high-bandwidth memory. The engineer will develop and optimize dopant implantation, profile control, and stress engineering while balancing junction performance, thermal budget compatibility, defectivity, and integration constraints across radically different product requirements.

What You'll Do

• Help develop and qualify high-current, medium-current, and low-energy ion implantation processes, including source/drain, substrate, channel, well, and halo implants for logic and memory devices
• Help optimize critical implant parameters: dopant species, energy, dose, tilt, rotation, beam current, and damage engineering to achieve precise junction profiles, sheet resistance, and leakage performance
• Help with ion implant processes
• Help qualify implant tools from installation to production readiness, including beam calibration, uniformity, angle control, wafer charging management, and chamber matching
• Help analyze implant process, dopant distribution, and device performance using first-principles, physics-based approaches to understand implantation mechanisms, amorphization, channeling, and transient enhanced diffusion (TED) interactions
• Help with root cause analysis for profile shifts, device param variation, and yield issues; establish inline metrology and control strategies; and drive systematic yield improvement
• Help drive development of next-generation implantation techniques, including plasma doping (PLAD) and advanced damage/activation strategies for sub-2nm nodes and specialized applications

What You'll Bring

• Currently pursuing a degree in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or related field
• Experience ion implanters
• Proficiency with implant metrology
• DOE skills and statistical analysis capability
• Excellent collaboration skills with the ability to work proactively across diffusion/anneal, thin films, integration, and equipment engineering teams
• Passion for ambitious, vertically integrated semiconductor programs and building high-performance compute technologies
