Hello All I am looking for a recipie that will allow me to deposit PECVD nitride or oxide on high aspect ratio structures at low temperatures say around 250 degC. The main reason is to prevent a polyimide layer on the wafer from degasing when the oxidation / nitridation is done at higher temperatures like 350deg C. Please let me know if anyone can point me to such a recipie. Any help in this regard will be much appreciated Looking forward to your replies Sincerely Anupama Anupama V.
