Design for Manufacture (DFM) Trends
With each reduction in IC feature size, additional manufacturing issues arise. These include increased complexity, higher clock frequencies, power dissipation, component density, and reliability.
The effects of the manufacturing process on the design need to be understood. Chip designers, lithography, mask-making, processing, and test engineers need better two-way communication.
More manufacturing-aware tools are coming onto the market. These tools take into account manufacturing tolerances, voltage sensitivity, and technology constraints. Considering manufacturing early in the design process can significantly improve the eventual semiconductor chip yield.
Significant DFM trends include:
