Abstract: Methods and apparatus for forming a thin film transistor (TFT) having a metal oxide layer. The method may include forming an amorphous metal oxide layer and treating the metal oxide layer with a silicon containing gas or plasma including Si4+ ions. The silicon treatment of the metal oxide layer helps fill the oxygen vacancies in the metal oxide channel layer, leading to a more stable TFT and preventing a negative threshold voltage in the TFT.

Abstract: One illustrative method disclosed herein includes forming a plurality of spaced-apart trenches in a semiconducting substrate to thereby define a fin structure for the device, forming a local isolation region within each of the trenches, forming a sacrificial gate structure on the fin structure, wherein the sacrificial gate structure comprises at least a sacrificial gate electrode, and forming a layer of insulating material above the fin structure and within the trench above the local isolation region. In this example, the method further includes performing at least one etching process to remove the sacrificial gate structure to thereby define a gate cavity, after removing the sacrificial gate structure, performing at least one etching process to form a recess in the local isolation region, and forming a replacement gate structure that is positioned in the recess in the local isolation region and in the gate cavity.

Abstract: A method for forming different active thicknesses on the same silicon layer includes masking the silicon layer and exposing selected regions of the silicon layer. The thickness of the silicon layer at the exposed regions is changed, either by adding silicon or subtracting silicon from the layer at the exposed regions. Once the mask is removed, the silicon layer has regions of different active thicknesses, respectively suitable for use in different types of devices, such as diodes and transistors.

Abstract: A semiconductor product has different active thicknesses of silicon on a single semiconductor substrate. The thickness of the silicon layer is changed either by selectively adding silicon or subtracting silicon from an original layer of silicon. The different active thicknesses are suitable for use in different types of devices, such as diodes and transistors.

Abstract: By providing a hard mask layer stack including at least three different layers for patterning a gate electrode structure, constraints demanded by sophisticated lithography, as well as cap layer integrity, in a subsequent selective epitaxial growth process may be accomplished, thereby providing the potential for further device scaling of transistor devices requiring raised drain and source regions.

Abstract: Gate electrodes with selectively tuned channel thicknesses are formed by selective epitaxial growth. Embodiments include forming shallow trench isolation regions in an SOI substrate, selectively removing the nitride stop layer and pad oxide layer in an exposed particular active region, and implementing selective epitaxial growth to increase the thickness of the semiconductor layer in the particular active region. Subsequently, the remaining nitride stop and pad oxide layers in other active regions are removed, gate dielectric layers formed, as by thermal oxidation, and the transistors completed.
