The silicon-oxide-containing layer is exposed to a nitrogen-containing plasma to introduce nitrogen into the layer. The nitrogen is subsequently thermally annealed within the layer to bond at least some of the nitrogen to silicon within the layer. The invention also encompasses a method of forming a transistor. A gate oxide layer is formed over a semiconductive substrate. The gate oxide layer comprises silicon dioxide. The gate oxide layer is exposed to a nitrogen-containing plasma to introduce nitrogen into the layer, and the layer is maintained at less than or equal to 400° C. during the exposing. Subsequently, the nitrogen within the layer is thermally annealed to bond at least a majority of the nitrogen to silicon. At least one conductive layer is formed over the gate oxide layer. Source/drain regions are formed within the semiconductive substrate, and are gatedly connected to one another by the at least one conductive layer. The invention also encompasses transistor structures.

摘要： Multiple pitch-multiplied spacers are used to form mask patterns having features with exceptionally small critical dimensions. One of each pair of spacers formed around a plurality of mandrels is removed and alternating layers, formed of two mutually selectively etchable materials, are deposited around the remaining spacers. Layers formed of one of the materials are then etched, leaving behind vertically-extending layers formed of the other of the materials, which form a mask pattern. Alternatively, instead of depositing alternating layers, amorphous carbon is deposited around the remaining spacers followed by a plurality of cycles of forming pairs of spacers on the amorphous carbon, removing one of the pairs of spacers and depositing an amorphous carbon layer. The cycles can be repeated to form the desired pattern. Because the critical dimensions of some features in the pattern can be set by controlling the width of the spaces between spacers, exceptionally small mask features can be formed.

摘要： A method suitable for use during fabrication of a semiconductor device such as a dynamic random access memory or a flash programmable read-only memory comprises etching through silicon nitride and pad oxide layers and into a semiconductor wafer to form a trench into the wafer. A shallow trench isolation (STI) layer is formed in the opening in the silicon nitride and in the trench in the wafer which will, under certain conditions, form with an undesirable void. The silicon nitride and pad oxide layers are removed, then an epitaxial silicon layer is formed on the silicon wafer between the STI. A gate/tunnel oxide layer is formed on the epitaxial silicon layer, then a word line is formed over the gate/tunnel oxide. The epitaxial silicon layer ensures that some minimum distance is maintained between the gate/tunnel oxide and the void in the STI. Wafer processing may then be continued to form a completed semiconductor device.
