Job description
From Volantis Semiconductor, Inc.’s job post, as they wrote it.
Location: Hybrid - SF
Employment: Full-time
Develop and qualify Volantis’s testing procedures for custom lasers and scale for mass production.
You will own development and implementation of testing and reliability procedures for our first- and second-generation custom laser designs, and their integration with the wafer-scale interposer.
Responsibilities
* Partnering with the laser design team to define test plans, specifications and pass/fail criteria for new individually addressable VCSEL array designs.
Read the full description
* Characterizing prototype devices (LIV, spectral, far-field/beam profile, polarization, thermal and high-speed modulation) and delivering timely analysis that feeds back into design iterations.
* Managing test data, including databases, wafer maps, yield analysis and SPC, to track device performance and process variation in conjunction with the designers.
* Designing, building and maintaining wafer- and die-level prober systems, test fixtures and automated test software.
* Owning qualification and ramp-up of VCSEL array product testing systems, scaling from R&D characterization to high-volume production test.
* Working with the laser design, packaging and wafer-scale interposer teams to prove out reliability of the VCSEL itself and the overall system.
Requirements
* Deep hands-on experience with semiconductor laser (preferably VCSEL) testing, characterization, validation, reliability and qualification.
* Experience designing prober systems, test fixtures and related software automation
* Proficiency with optical and electrical test equipment such as SMUs, optical spectrum analyzers, power meters, VNAs, and beam profilers
* Ability to work independently as well as in cross-functional teams including quality and packaging
Nice to have
* Experience qualifying and using contract manufacturers for large volume production test of VCSELs
* Experience testing high-density VCSEL arrays, both top and bottom side emitting.
* High speed direct modulation laser diode test experience
* Understanding of sources of process variation and statistical process control for yield improvement
* Laser reliability qualification (e.g., Telcordia GR-468) and/or laser packaging experience
