I ran six passes through STS PECVD, Dual frequency nitride is still NOT
working correctly.
We are up for Low Frequency oxides and High Frequency nitride. In the
pass I've ran recipes before where everything seem to work and than
STS PECVD started having errors so again this may still be intermittent
problems. Stay with the system while processing.
Low Frequency oxide deposition rate was 393A / min. with the index of
refraction 1.47. NORMAL!!!!!
High Frequency Nitride deposition rate was 99A / min with the index of
refraction 2.06, NORMAL!!!!
The MFC for nitrogen is sitting next to the Argon toggle. Please do NOT
touch this MFC, it is very sensitive.
Regards,
Jeannie
