| 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 |
