摘要:
A method for controlling surface morphology of a transparent conductive oxide film (TCO) is provided. A substrate is provided as a basis for forming a solar cell. Onto the substrate, a seed layer is deposited. Then, the method includes depositing the transparent conductive oxide film (TCO) above the seed layer. The seed layer is adapted to control the surface morphology of the transparent conductive oxide film. The surface of the transparent conductive oxide film is etched in order to provide a front contact of the solar cell.

A method and apparatus for performing ALD deposition of hafnium oxide on a substrate is provided. The apparatus includes a process chamber, a precursor delivery subsystem, an oxidizer delivery subsystem, a purge gas subsystem, a solvent flush subsystem, and optional solvent recovery and purification subsystems. The method includes pulsing precursor compounds into the process chamber in sequence. While one precursor is pulsed, purge gas is provided through the other precursor line. After pulsing, precursor lines are purged, and the chamber is evacuated and purged. A solvent flush step is employed to remove precursor deposits that build up in piping over time.
