MICRO: Manufacturing Effectiveness
on a 35-nm gate-level structure, and (b) a 22-nm line-end extension in the x direction in a 65-nm MI trench. For unpatterned-wafer inspection, ISMI has developed standard wafers with future-generation film and polystyrene latex (PSL) spheres as small as 20 nm. PSL spheres are used to simulate

MICRO: Green Manufacturing
with either a dHF/rinse or DIO3/rinse followed by spin drying in nitrogen. A one-minute, three-cycle process can remove 87% of Al2O3 particles, 97% of Si3N4 particles, and 99.5% of polystyrene latex particles. In contrast to methods that apply dHF and DIO3 simultaneously, repetitive SCROD cleaning does

Measuring Residual Stress In Transparent Plastics
shrinkage, uneven cooling, or nonuniform flow. Stress evaluation can be quantified using a compensator. Photo: Strainoptic Technologies. In some polymers, the process-induced orientation enhances mechanical properties. For example, biaxial orientation of PET or polystyrene film ensures improved strength
