Results Test by Artem Shikin @ Fotonik
Etch rate of PECVD BPSG 39.4nm/min (22-01-2016)
Selectivity to resist [:1] Not known
Wafer uniformity (100mm) Not known
Profile [o] Not known
Wafer uniformity map (click on the image to view a larger image) Not known
SEM profile images NONE
Comment Tested on a plane BPSG layer. The etch rate is much lower for an etch time of e.g. 5s
