摘要: Methods for depositing a material atop a substrate are provided herein. In some embodiments, a method of depositing a material atop a substrate may include exposing a substrate to a silicon containing gas and a reducing gas; increasing a flow rate of the silicon containing gas while decreasing a flow rate of the reducing gas to form a first layer; and depositing a second layer atop the first layer.

摘要: The present invention generally provides an apparatus and method for eliminating the “first wafer effect” for plasma enhanced chemical vapor deposition (PECVD). One embodiment of the present invention provides a method for preparing a chamber after the chamber being idle for a period of time. The method comprises a cleaning step followed by a season step and a heating step adapted to the length of the idle time.
