摘要: A method and apparatus for oxidizing materials used in semiconductor integrated circuits, for example, for oxidizing silicon to form a dielectric gate. An ozonator is capable of producing a stream of least 70% ozone. The ozone passes into an RTP chamber through a water-cooled injector projecting into the chamber. Other gases such as hydrogen to increase oxidation rate, diluent gas such as nitrogen or O2, enter the chamber through another inlet. The chamber is maintained at a low pressure below 20 Torr and the substrate is advantageously maintained at a temperature less than 800° C. Alternatively, the oxidation may be performed in an LPCVD chamber including a pedestal heater and a showerhead gas injector in opposition to the pedestal.

摘要: Methods of fabricating an oxide layer on a semiconductor substrate are provided herein. The oxide layer may be formed over an entire structure disposed on the substrate, or selectively formed on a non-metal containing layer with little or no oxidation of an exposed metal-containing layer. The methods disclosed herein may be performed in a variety of process chambers, including but not limited to decoupled plasma oxidation chambers, rapid and/or remote plasma oxidation chambers, and/or plasma immersion ion implantation chambers. In some embodiments, a method may include providing a substrate comprising a metal-containing layer and non-metal containing layer; and forming an oxide layer on an exposed surface of the non-metal containing layer by exposing the substrate to a plasma formed from a process gas comprising a hydrogen-containing gas, an oxygen-containing gas, and at least one of a supplemental oxygen-containing gas or a nitrogen-containing gas.

摘要: Methods and apparatus for selective one-step nitridation of semiconductor substrates is provided. Nitrogen is selectively incorporated in silicon regions of a semiconductor substrate having silicon regions and silicon oxide regions by use of a selective nitridation process. Nitrogen containing radicals may be directed toward the substrate by forming a nitrogen containing plasma and filtering or removing ions from the plasma, or a thermal nitridation process using selective precursors may be performed. A remote plasma generator may be coupled to a processing chamber, optionally including one or more ion filters, showerheads, and radical distributors, or an in situ plasma may be generated and one or more ion filters or shields disposed in the chamber between the plasma generation zone and the substrate support.
