    摘要: Embodiments include a method comprising depositing a hard mask layer over a first layer, the hard mask layer including; lower hard mask layer, hard mask stop layer, and upper hard mask. The hard mask layer and the first layer are patterned and a spacer deposited on the patterned sidewall. The upper hard mask layer and top portion of the spacer are removed by selective etching with respect to the hard mask stop layer, the remaining spacer material extending to a first predetermined position on the sidewall. The hard mask stop layer is removed by selective etching with respect to the lower hard mask layer and spacer. The first hard mask layer and top portion of the spacer are removed by selectively etching the lower hard mask layer and the spacer with respect to the first layer, the remaining spacer material extending to a second predetermined position on the sidewall.

    摘要: A method including providing fins etched from a semiconductor substrate and covered by an oxide layer and a nitride layer, the oxide layer being located between the fins and the nitride layer, removing a portion of the fins to form an opening, forming a dielectric spacer on a sidewall of the opening, and filling the opening with a fill material, wherein a top surface of the fill material is substantially flush with a top surface of the nitride layer. The method may further include forming a deep trench capacitor in-line with one of the fins, removing the nitride layer to form a gap between the fins and the fill material, wherein the fill material has re-entrant geometry extending over the gap, and removing the re-entrant geometry and causing the gap between the fins and the fill material to widen.

    摘要: SOI structures with silicon layers less than 20 nm thick are used to form ETSOI semiconductor devices. ETSOI devices are manufactured using a thin tungsten backgate encapsulated by thin nitride layers to prevent metal oxidation, the tungsten backgate being characterized by its low resistivity. The structure includes at least one FET having a gate stack formed by a high-K metal gate and a tungsten region superimposed thereon, the footprint of the gate stack utilizing the thin SOI layer as a channel. The SOI structure thus formed controls the Vt variation from the thin SOI thickness and dopants therein. The ETSOI high-K metal backgate fully depleted device in conjunction with the thin BOX provides an excellent short channel control and lowers the drain induced bias and sub-threshold swings. The structure supports the evidence of the stability of the wafer having a tungsten film during thermal processing, during STI and contact formation.
