LED manufacturing cost simulation tool

System Plus Consulting has developed a powerful cost simulation tool to evaluate the cost of any LED device: From single chip to complex structures

LED CoSim+ is a process-based costing tool used to evaluate the manufacturing cost per wafer using your own inputs or using the pre-defined parameters included in the tool. It is possible to enter any LED process flow or component. LED CoSim+ includes a comprehensive database:

  • Fab unit database
  • Equipment database
  • Consumables database
  • Wafer database
  • Process Flow database

Due to their particular manufacturing process (GaNepitaxy, specific packaging…), the cost of LED devices can be difficult to estimate. Components such as regular LED, High Brightness LED or Ultra High Brightness LED involve very different process steps. LED CoSim+ is a powerful cost simulation tool designed for the LED community featuring:

  • Highly flexible anduser-friendly hierarchical view where each process step can be moved, modified or deleted
  • Multiple process flows:
    • Hierarchical description for multiple dies from different technologies or processes.
    • Simulating cost according to different conditions (region, cleanroom , process, etc.)
  • Two calculation modes: for dedicated fabs and non-dedicated fabs
  • Integrated equipment, wafer & material databases
  • An unlimited number of process steps or process flows to store in libraries
  • Up to five simultaneous scenarios allowing the user to run sensitivity analysis and compare results like yield improvement, manufacturing location impact on cost, etc.
  • Multiple subcontracting operations: costs of usually externalized operations can be precisely evaluated by setting their individual regional and commercial parameters.

An optional Power process library and components library are available for some LED devices:

  • The LED components Library includes front-end and back-end processes for some devices from Cree, Nichia, Citizen, Lumileds, Osram, Seoul Semiconductors, Sharp, Visera…
  • The LED processes Library LED includes front-end processes only from Cree, Nichia, Lumileds, Osram, Seoul Semiconductors, Sharp, Visera, Semileds…
