AttoTude is at the forefront of revolutionizing data centers through advanced interconnect technology based on wired THz transceivers.  By adapting the fiber from photonics and advancing today's ASICs to THz, our innovative AttoEngine eliminates networking bottlenecks, enabling high-speed interconnects for AI data centers.

AttoTude is seeking a hands-on Fabrication Technician or early-career Associate Process Engineer to support the development and execution of micro- and nanofabrication processes for our core technology. This role is based in the Berkeley Nanolab and works closely with AttoTude engineers and researchers to fabricate, iterate, and characterize devices in a fast-moving R&D environment.

This position is well-suited for either:

• An experienced fabrication technician who enjoys executing and improving complex process flows, or
• A recent undergraduate graduate who wants a highly hands-on role that can grow into a process or device engineering position over time.

The ideal candidate is detail-oriented, safety-conscious, and excited to work on cutting-edge fabrication challenges in a shared-user cleanroom.

Key Responsibilities

• Execute micro- and nanofabrication process flows in the Berkeley Nanolab cleanroom
  • Operate fabrication equipment including:

• Photolithography tools (spin coaters, mask aligners, developers)
• Thin film deposition systems (evaporation, sputtering, PECVD)
• Dry and wet etching tools (RIE, DRIE, wet etch)
• Metrology and inspection tools (optical microscopy, profilometry, ellipsometry, SEM)
  • Support process development, optimization, and repeatability for AttoTude devices
  • Maintain detailed fabrication logs, travelers, and process documentation
  • Identify, troubleshoot, and communicate process or tool issues impacting device yield
  • Coordinate with Berkeley Nanolab staff on tool access, maintenance, and scheduling
  • Follow all Berkeley Nanolab safety, chemical handling, and cleanroom protocols
  • Contribute to continuous improvement of AttoTude fabrication workflows

For early-career candidates:

• Gradually take on increased ownership of process modules or device steps
• Participate in process integration discussions and experimental planning
• Learn to analyze yield, variability, and failure modes with guidance from senior engineers
