Title: Silicon nitride composite hdp/cvd process
Inventor: CHENG LIE-YEA
IPC: H01L21/318
Filed: 2000-02-07
Abstract: PROBLEM TO BE SOLVED: To enhance the performance of a silicon oxide film being deposited using HDP-CVD by providing a barrier layer under a silicon oxide layer thereby preventing hydrogen from being diffused into the structure. SOLUTION: A barrier layer 42 including a first dielectric film 46 and a silicon nitride film 44 is deposited on a substrate 12. A silicon oxide layer 26 is then deposited on the barrier layer 42 by HDP-CVD. When TEOS 46 or the barrier layer 42 of the silicon nitride is provided, excess hydrogen generated in the silicon oxide layer 26 by the HDP-CVD can be prevented from being diffused from the oxide layer into the gate through a metal layer M1. Since the silicon nitride film 44 prevent diffusion of hydrogen from the HDP-CVD oxide layer to the gate, integrity of gate oxidation becomes sensitive and the multiplex load resistance of an IC can be sustained at a high desired level. Consequently, the performance of a silicon oxide film being deposited using HDP-CVD can be enhanced.
