Abstract:
A CVD apparatus comprising:a first reaction chamber;a first substrate holder for supporting a first single substrate in said first reaction chamber;a first gas introducing means for introducing a first process gas into said first reaction chamber;a first CVD means for performing a chemical vapor deposition on said first substrate in said first reaction chamber;a second reaction chamber connected to said first reaction chamber through a gate valve;a second substrate holder for supporting a second single substrate in said second reaction chamber;a second gas introducing means for introducing a second process gas into said second reaction chamber;ECR means including a microwave source and a magnetic field inducing means to excite said second process gas;an A.C. power source to further energize said second process gas excited by said ECR means,wherein said first and second single substrates are disposed in the first and second reaction chambers so that a flow of the respective process gases is substantially perpendicular to the first and second single substrates and said gate valve is perpendicularly disposed with respect to a major surface of said first and second single substrates as supported in the respective reaction chambers.
