Chip-AMAG7 HARhole, 1.0 µm depth, SiO2 on Si, C60P120 anchor target
Chip-AMAG7 HARhole, 1.0 µm depth, SiO2 on Si, C60P120 anchor target
AMAG7 hole/trench module etched into 1.0 µm deep SiO2 to achieve etched HAR hole and trench features, with holes terminating on Si substrate. The anchor target is C60P120, but larger hole sizes also pattern successfully, along with larger trenches.
