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.
•
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
