US Patent 7670646 Methods for atomic-layer deposition

Atomic-Layer deposition systems and methods provide a variety of electronic products. In an embodiment, a method uses an atomic-layer deposition system that includes an outer chamber, a substrate holder, and a gas-distribution fixture that engages or cooperates with the substrate holder to form an inner chamber within the outer chamber. The inner chamber has a smaller volume than the outer chamber, which leads to less time to fill and purge during cycle times for deposition of materials.
