High aspect ratio via etching conditions for deep trench of silicon
WitrynaChip scale loading In figure 3a we present the influence of nested ring size (2.5, 5, 10 mm edge length) on the etched depth of a 32 µ m line. The etching time was 90 minutes. For the 2.5 mm rings etched depth is independent of local load percentage, but for 5 mm and 10 mm chips there is a local loading effect.
