1. Edge placement error measurement in lithography process with die to database algorithm

The control of edge placement error (EPE) is playing key role in the patterning of advanced technology node. In past instance, EPE between upper layer and under layer was measured by e-beam metrology system. In case of photoresist pattern, it is difficult to observe under layer pattern and difficult to measure EPE. This study provides the measurement method of EPE on photoresist layer resulting from variation of scanner tool condition by using Die to Database technology with large image size which include huge number of patterns.

2. E-beam inspection of single exposure EUV direct print of M2 layer of N10 node test vehicle
