Lumiode, Inc.


Job Req: TFT Device Modeling 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 fully integrated micro-LED displays, Lumiode’s solutions are well suited for AR/VR (Augmented Reality/Virtual Reality), HUD (Head-Up Display) and projection applications.

Position Description: We are looking for an experienced display TFT device and array modeling engineer. The ideal candidate will be skilled in performing TFT TCAD simulation, display circuit design/optimization, SPICE model extraction and simulation. Candidates should be able to translate process parameters into realistic simulation inputs and also contribute to circuit design for the driving and measurement of arrayed micro-LEDs. We are looking for a self-motivated team player who can work with all levels of our technical team. Responsibilities include:

  • Use TCAD based software for modeling TFT transistor and LED

  • Manage TCAD models and calibrate with test data

  • Predict device performance from proposed changes coordinated with the Process team and provide recommendations

  • Develop SPICE models through test data extraction

  • Perform 3-dimensional RC extractions at both the pixel and display level

  • Perform DC and AC simulations and timing analysis for circuits at both the pixel and display level

Key Requirements:

  • M.S. in Electrical Engineering with at least 5 years work experience in device simulation

  • Strong background in solid-state device physics and analog circuit design

  • Experience in using semiconductor TCAD 2D, 3D modeling and layout tools such as Silvaco (preferred) or Synopsis, Mentor Graphics, Cadence or Tanner, SPICE

  • Ability to perform computer modelling and simulation using SPICE

  • Experience in measuring and characterizing IV and CV of TFT devices

  • Understanding of typical TFT and panel fab processes

  • Experience with TFT and solid state device array related design and modeling

  • Bonus points for experience with power circuits, measurement circuits, and display row and column driver IC designs
