Re: DFM issue
DfM: Design for Manufacturing or Design for Manufacturability: methodology which, when applied to microelectronics, permits to improve the yield/robustness of integrated circuits, taking into account the constraints of manufacturing in the early design phases.
The DfM Guidelines are a set of recommendation for designers.
These guidelines are defined for a given process of a given technology and are highly influenced by the materials, equipment, settings.
As a consequence, the DfM guidelines are based on the engineering judgment of process experts (often using the parametric test results of layout process structures on advanced reticles).
These guidelines are also discussed and reviewed with design experts.
For the 65 nm guidelines for expl , experts from the following areas have participated:
• Back-End process
• Front-End process
• Yield enhancement
• eDRAM design
• Full Custom design
• IO design
• SoC design
• Std cells design
• SRAM/ROM design
