Patent Images
1. A CVD method for forming a silicon nitride film on a target substrate, the method comprising:
- heating the substrate accommodated in a process container, at a process temperature; and
supplying a process gas including hexaethylamino-disilane gas and ammonia gas onto the substrate heated at the process temperature, thereby depositing a silicon nitride film on the substrate.

Abstract
A CVD method is to form a silicon nitride film on a target substrate (W). The method includes heating the substrate (W) accommodated in a process container (8), at a process temperature, and supplying a process gas including hexaethylamino-disilane gas and ammonia gas onto the substrate (W) heated at the process temperature, thereby depositing a silicon nitride film on the substrate (W).

6. A CVD method for forming a silicon nitride film on a target substrate, the method comprising:
-
heating the substrate accommodated in a process container, at a process temperature; and
alternately supplying a first process gas including hexaethylaminodisilane gas and a second process gas including ammonia gas in cycles onto the substrate heated at the process temperature, thereby depositing a silicon nitride film on the substrate, wherein supplying the second process gas comprises turning the second process gas into plasma for excitation. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
