VCSEL Industrialization & Sourcing M/F



Job description


ST is one of the worldwide leaders in Imaging sensor and time of flight products for mobile & automotive application. Camera sensor and photonics products are made by the Imaging division (IMG) of ST. Some components inside Photonics products are co-designed with different external suppliers and then assembled by ST to produce the final product for the customer. One key outsourced component is the illuminator such as VCSELs (Vertical-Cavity Surface-Emitting Laser), EEL (Edge-Emitting Laser) & LED (Light-emitting diode)


Illumination sourcing is followed by the IMG technical sourcing team located across 3 sites; Taiwan, Grenoble, Santa Clara. The team is working closely with different suppliers engaged in the design and manufacturing of the optical illumination.


The engineer for this job position will be based in our Taiwan/Hsinchu office

The candidate will be leading different suppliers during the development phase of new components & manage quality/capacity crisis. The candidate will have the responsible for one, a few or a family of Optics & optoelectronics components such as VCSEL, EEL, LED & Photodiode & will manage:


Component definition with module design team & system architect
Execution of component prototyping with the supplier
Responsible for writing and consolidating inputs into the component procurement specification.
Qualification of component (characterization & reliability…)
Qualification of manufacturing line (process flow, FMEA, process buy-off…)
High-volume production bring-up & review of yield & performances
Coordination between ST project team, ST assembly plants and suppliers
Coordination between supplier & ST teams for failure-analysis

The candidate must have strong semiconductor process knowledge. Good understanding of optic physics, III-V process are a plus.


The candidate will also support advanced sourcing activity by surveying the illumination ecosystem technology roadmap.

The candidate might also extend expertise to other optical components (filters, lenses, diffusers…) as necessary.


The job holder will have to travel often in Asia (Suppliers and ST sites) and, occasionally, to Europe & USA



Key Skills and Experience
Semiconductor process knowledge

Strong Communication Skills

Ability to work with multi-functional team


Excellent verbal and written skills


Energetic team player who is eager to learn




Additional Skills and Experience
Experience with optical component incl. manyfacturing Front End and Back-End process. VCSEL & Laser diode device is preferred

Good understanding of optic physics,

2-3 years experience in semiconductor manufacturing with knowledge of manufacturing processes, industrial equipment, and concepts such as Design for Manufacturing/Assembly

Strong compound semiconductor process knowledge + fab and back end processes are a plus.

Analytic and data analysis skills via Excel, JMP, Matlab or equivalent


Preferred degrees include: Electrical Engineering, Materials Science or Physics , or similar field.
