Silicon nitride etch with STS recommended silicon nitride recipe
- Profiles of etched lines. DUV resist mask and about 320nm Si3N4 on Silicon. The barc layer was etch in 1min15sek with the AOE barcetch recipe, done Marts 2016 by bghe
Silicon nitride etch with the standard silicon oxide etch
- Etch of LPCVD nitride with DUV KRF resist as mask. The mask is still on. Made by BGHE February 2015
