Methods for depositing semiconductor films

A method for forming a film on a substrate in a semiconductor process chamber includes forming a first layer on the substrate using a plasma enhanced process and a gas compound of a chloride-based gas, a hydrogen gas, and an inert gas. The process chamber is then purged and the first layer is therma...

Beschreibung
Zusammenfassung:	A method for forming a film on a substrate in a semiconductor process chamber includes forming a first layer on the substrate using a plasma enhanced process and a gas compound of a chloride-based gas, a hydrogen gas, and an inert gas. The process chamber is then purged and the first layer is thermally soaked with a hydrogen-based precursor gas. The process chamber is then purged again and the process may be repeated with or without the plasma enhanced process until a certain film thickness is achieved on the substrate.
