Prototype Turnaround Time (TAT)

• Designs that require a complete mask set (Cell- Based) will always require more time to manufacture than designs which use a basic set of diffusion masks and only require customization at the metal layers (Array-Based).

• This difference in time could be anywhere from one week to 4 weeks depending on how fast the silicon vendor can get masks from the mask shop and depending on how long the FAB cycle is for a given process.
