The oxide layer is formed at a temperature of less than 400° C. using an inductively coupled plasma source. In some aspects of the method, the oxide layer is more than 20 nanometers (nm) thick and has a refractive index between 1.45 and 1.47. In some aspects of the method, the oxide layer is formed by plasma oxidizing the silicon layer, producing plasma oxide at a rate of up to approximately 4.4 nm per minute (after one minute). In some aspects of the method, a high-density plasma enhanced chemical vapor deposition (HD-PECVD) process is used to form the oxide layer.

    摘要: A method is provided for additionally oxidizing a thin-film oxide. The method includes: providing a substrate; depositing an MyOx (M oxide) layer overlying the substrate, where M is a solid element having an oxidation state in a range of +2 to +5; treating the MyOx layer to a high density plasma (HDP) source; and, forming an MyOk layer in response to the HDP source, where k>x. In one aspect, the method further includes decreasing the concentration of oxide charge in response to forming the MyOk layer. In another aspect, the MyOx layer is deposited with an impurity N, and the method further includes creating volatile N oxides in response to forming the MyOk layer. For example, the impurity N may be carbon and the method creates a volatile carbon oxide.

    摘要: A high-density plasma method is provided for forming a SiOXNY thin-film. The method provides a substrate and introduces a silicon (Si) precursor. A thin-film is deposited overlying the substrate, using a high density (HD) plasma-enhanced chemical vapor deposition (PECVD) process. As a result, a SiOXNY thin-film is formed, where (X+Y 0). The SiOXNY thin-film can be stoichiometric or non-stoichiometric. The SiOXNY thin-film can be graded, meaning the values of X and Y vary with the thickness of the SiOXNY thin-film. Further, the process enables the in-situ deposition of a SiOXNY thin-film multilayer structure, where the different layers may be stoichiometric, non-stoichiometric, graded, and combinations of the above-mentioned types of SiOXNY thin-films.

    摘要: A method is provided for forming a silicon nitride (SiNx) film. The method comprises: providing a Si substrate or Si film layer; optionally maintaining a substrate temperature of about 400 degrees C., or less; performing a high-density (HD) nitrogen plasma process where a top electrode is connected to an inductively coupled HD plasma source; and, forming a grown layer of SiNx overlying the substrate. More specifically, the HD nitrogen plasma process includes using an inductively coupled plasma (ICP) source to supply power to a top electrode, independent of the power and frequency of the power that is supplied to the bottom electrode, in an atmosphere with a nitrogen source gas. The SiNx layer can be grown at an initial growth rate of at least about 20 Å in about the first minute.

    摘要: A piston-cylinder actuator includes a unique mount for an absolute-position sensor. The mount is made from a bearing material provides a flexible connection between the sensor mount and the cylinder housing. This flexible connection allows the piston rod to deflect naturally, under its own weight or under other laterally-directed forces, while maintaining the distance and perpendicularity between the sensor and the rod surface, within acceptable limits. The sensor mount is made from a bearing material that will allow it to float directly on the rod surface without scuffing or otherwise damaging the rod surface, particularly the markings or other indicia on that surface. Due to the flexible connection between the sensor mount and the cylinder housing, the proper distance between the sensor and the rod surface can be maintained at all times.
