CONTINUOUS FLOW DEPOSITION SYSTEM
First Claim
1. an atomic layer deposition system comprising:
- a) a deposition chamber;
b) a first reaction chamber that is positioned in the deposition chamber and that contains a first reactant species, a monolayer of the first reactant species being deposited on a substrate passing through the first reaction chamber;
c) a second reaction chamber that is positioned in the deposition chamber, the second reaction chamber containing a second reactant species, a monolayer of the second reactant species being deposited on a substrate passing through the second reaction chamber; and
d) a transport mechanism that transports a substrate in a path through the first reaction chamber and through the second reaction chamber at a constant transport rate, thereby depositing a film on the substrate by atomic layer deposition, wherein a shape of at least one of the first and the second reaction chambers is chosen to achieve a constant exposure of the substrate to a respective one of the first and the second reactant species when the transport mechanism transports the substrate in the path through the respective one of the first and the second reaction chamber at the constant transport rate.

Abstract
An atomic layer deposition system is described that includes a deposition chamber. A first and second reaction chamber are positioned in the deposition chamber and contain a first and a second reactant species, respectively. A monolayer of the first reactant species is deposited on a substrate passing through the first reaction chamber. A monolayer of the second reactant species is deposited on a substrate passing through the second reaction chamber. A transport mechanism transports a substrate in a path through the first reaction chamber and through the second reaction chamber, thereby depositing a film on the substrate by atomic layer deposition. The shape of the first and the second reaction chambers are chosen to achieve a constant exposure of the substrate to reactant species when the transport mechanism transports the substrate in the path through the respective reaction chambers at the constant transport rate.
