Lumiode, Inc.

 

TFT Process Engineer

 

About Us: Lumiode is a fast growing, fabless semiconductor company commercializing a novel micro-LED platform delivering ultra-high brightness, low power, small form factor displays. As a leading developer of monolithic micro-LED displays, our integration of thin film transistors (TFTs) and micro-LEDs is well suited for AR/MR, head-up display (HUD) and other consumer, industrial and automotive display applications.

​

Position Description: We are looking for an experienced TFT process engineer. The ideal candidate will be skilled in LTPS and/or IGZO TFT process development and fabrication, ideally with experience in ramping technology from R&D to volume production. Candidates should also be able to translate process parameters into realistic simulation inputs and contribute to applicable process simulation and modeling. We are looking for a self-motivated team player who can work with all levels of our technical team. This is a great opportunity to make a big impact at a fast-growing startup. Responsibilities include:

  • Improve existing and design new process recipes for fabricating poly-Si TFTs from concept demonstration to manufacturing.

  • Utilize in-depth knowledge of the relationship between materials, process, and device physics to design and execute process experiments (DOEs) to optimize TFT performance.

  • Identify process improvements to increase TFT yield and reliability.

  • Prepare process development plans.

  • Test TFTs using hardware including but not limited to manual and semi-automatic probe stations, parameter analyzers, oscilloscopes, and impedance analyzers.

  • Identify and investigate TFT device failures.

  • Apply characterization techniques to study individual materials and interfaces in the TFT device.

  • Mine and analyze large datasets.

 

Key Requirements:

  • MS or PhD in Electrical Engineering, Physics, Materials Science, or other related fields with an emphasis on semiconductor process.

  • Five or more years industry experience in a field involving semiconductor materials and process, transistor processing, and transistor testing.

  • Knowledge of transistor device physics and the interaction between process and device performance.

  • Experience with process development, designing experiments, and failure analysis.

  • Strong background in semiconductor/cleanroom processing tools and modules including PECVD, wet and dry etching, and PVD of thin films.

  • Experience with material characterization and electrical characterization techniques including SEM, AFM, FIB, C-V, breakdown voltage, etc.

  • Experience testing and characterizing transistors using manual and semi-automated probe stations, probe manipulators, and probe cards.

  • Experience interfacing with test equipment and managing large data sets (i.e. Python, JMP)

  • Strong verbal and written communication skills

  • Detail-oriented

 

Bonus points:

  • Knowledge of laser processing of silicon

  • Experience in display industry

  • Experience with process transfer

  • Experience in device simulation

  • Experience with mask design and layout
