Process Engineer (Packaging & Assembly)

Fremont, CA
Technology Organization – Fabrication
As Process Engineer (Packaging & Assembly), you will be in charge of sustaining activities in backend packaging and assembly process toward building quantum integrated circuits. You will spend your time immersed in the hands-on fabrication of these devices. You will work in a fast-paced environment with a wide range of engineers and scientists in process, integration, design and quantum engineering.

Key Responsibilities

    • Take immediate ownership of assembly and packaging processes including, but not limited to, die attach, wire bonding, flip chip attach, underfill, solder ball attach, wafer singulation, wafer bonding, etc.
    • Create specification, packaging diagram and written work instructions.  Utilize die map, die inspection report and e-test results for product pick & place for assembly.
    • Establish process metrologies, key metrics, and parameters. Document and maintain monitors and statistical controls to run a predictable and capable process.
    • Define and specify requirements for assembly tooling, fixtures and equipment to support manufacturing operations and damage free die handling.
    • Guide technicians and operators in process and equipment troubleshooting. 
    • Support yield and efficiency improvement on die attach, wire bonding, or any other assembly process assigned by management.
    • Support assembly and packaging development activities working through the evolution details of next generation process/architecture/product/approach, collaborating with other frontend and backend modules.
    • Key member of the team to help establish Rigetti Fab as a leading quantum integrated circuit foundry.
    • Position may require the ability to obtain a DoD Secret clearance

Additional Responsibilities

    • Develop and sustain processes and deliver products that may involve both internal and external houses and service providers.
    • Maintain and monitor failure pareto from daily production activities and recommend product and process improvements to enhance yield and efficiency.
    • Organize failure data, draw correlations from process interactions and present results in a concise fashion.
    • Work with other fab team members, be responsible for tools, material, metrology, and process aspects of backend modules.
    • Prepare process requirement documents in defining and acquiring new equipment. Install and qualify new equipment and establish process.
    • Should have good planning with excellent written and verbal communication skills.

About You

    • Disciplined hands-on approach to development work and technical problem solving.
    • MS and/or Ph.D. in Science or Engineering field.
    • At least 7+ years of hands-on experience in wide range of semiconductor/MEMS assembly and packaging tools, such as wire bonders, die attach, epoxy dispense, flip-chip assembly, SMT, flux/solder (paste and solder balls), underfilling and cure, and relevant metrology tools. Hands-on experience in die-prep tools, such as wafer mount, wafer singulation, and die eject and handling. Familiar with temporary and permanent wafer bonding.
    • Good understanding of cross-functional packaging areas is definite plus. Familiarity in reviewing Si floor plan, package layout and architecture, thermal, mechanical, material, component & system level reliability, testing and failure analysis preferred.
    • Strong oral communication skills. Ability to work in cross-functional dynamic team.
    • Demonstrated ability to creatively and successfully manage competing priorities; must be able to identify opportunities to drive multiple efforts simultaneously.
    • Strong background in SPC and DOE methodologies, and data analysis.
    • Comfortable working in cleanroom fab adhering to HAZMAT and ESD practices.
    • High degree of comfort with flexible, agile small company environment. Flexibility in work hours and work days.
    • Comfortable with MS Office products, JMP, Solid Works, Google-docs
