Webinspection (ADI) and after-etch inspection (AEI) layer structures. For these structures, the critical measurement parameters include side wall angle (SWA) and critical dimension (CD). For production process control of these structures, a metrology tool must utilize a non-destructive measurement technique, and have high sensitivity, precision WebThis technique is particularly useful when applied at the after-develop inspection (ADI) step, as it allows manufacturers to rework their process without scrapping wafers. It is also expected that OCD technology will become an indispensible metrology technique in advanced technology nodes below 40 nm, where double-patterning and/or immersion ...
