Abstract

A high-density plasma hydrogenation method is provided. Generally, the method comprises: forming a silicon (Si)/oxide stack layer; plasma oxidizing the Si/oxide stack at a temperature of less than 400.degree. C., using a high density plasma source, such as an inductively coupled plasma (ICP) source; introducing an atmosphere including H2 at a system pressure up to 500 milliTorr; hydrogenating the stack at a temperature of less than 400 degrees C., using the high density plasma source; and forming an electrode overlying the oxide. The electrode may be formed either before or after the hydrogenation. The Si/oxide stack may be formed in a number of ways. In one aspect, a Si layer is formed, and the silicon layer is plasma oxidized at a temperature of less than 400 degrees C., using an ICP source. The oxide formation, additional oxidation, and hydrogenation steps can be conducted in-situ in a common chamber.
