Abstract:
Techniques are disclosed for methods and apparatuses for performing continuous-flow plasma enhanced atomic layer deposition (PEALD). Plasma gas, containing one or more component gases, is continuously flowed to a planar inductive coupled plasma source attached at an upper end of a cylindrical chamber. Plasma is separated from the ALD volume surrounding a wafer/substrate in the lower end of the chamber by a combination of a grounded metal plate and a ceramic plate. Each plate has a number of mutually aligned holes. The ceramic plate has holes with a diameter less than 2 Debye lengths and has a large aspect ratio. This prevents damaging plasma flux from entering the ALD volume into which a gaseous metal precursor is also pulsed. The self-limiting ALD reaction involving the heated substrate, the excited neutrals from the plasma gas, and the metal precursor produce an ultra-uniform, high quality film on the wafer. A batch configuration to simultaneously coat multiple wafers is also disclosed.
