Abstract
The uniformity of silicon dioxide as a passivation layer deposited by PECVD using IPL 2000 E/D was studied. A four inch wafer was used for the deposition using the PECVD technique with two reactant gases, silane (SiH4) and nitrous oxide (N2O), with substrate temperature of 300 °C. Four samples were deposited at different times: 5, 10, 15 and 20 minutes. The deposited oxide thickness and its respective refractive index were measured using an ellipsometer and plotted against the deposition time. The deposition parameters were also observed and reported
