2002 Changes • Litho Metrology • Change basis of CD Precision to Litho process variance on printed gate. Precision is even more difficult to achieve • Add better discussion of why red (new color) • LER is now off-line • Interconnect • Better define copper void and low k pore measurement needs in Interconnect Metrology Tech Requirements Table • Push red out based on testing of methods
