Challenges seen for seamless DFM, says expert

What is a semiconductor?
A class of materials, for instance silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber). It displays relatively high resistance in pure state and much lower resistance when it contains small amounts of certain impurities.

What is design for manufacturability (DFM)?
The design methodology called "design for manufacturability" (DFM) includes a set of techniques used to modify the design of semiconductors in order to make them more manufacturable by improving their functional yield, parametric yield, reliability etc.
