    摘要: A showerhead used for dispensing gas over a wafer in chemical vapor deposition (CVD), especially for CVD of metals. The patterns of holes is tailored to compensate for thermal and other effects, in particular by increasing the density of holes toward the periphery of the wafer in three or more zones. Such a variable pattern is particularly useful for liquid precursors that are atomized in a carrier gas, in which case a second perforated plate in back of the showerhead face can be eliminated, thereby reducing the flow impedance and the required pressure of the liquid-entrained gas, which tends to deposit out at higher pressures. The reduce flow impedance is particularly useful for CVD of copper.

    摘要: A showerhead used for dispensing gas over a wafer in chemical vapor deposition (CVD), especially for CVD of copper in a thermal process using a precursor such as HFAC-Cu-TMVS. The patterns of holes is tailored to compensate for thermal and other effects, in particular by increasing the density of holes toward the periphery of the wafer in three or more zones. Such a variable pattern is particularly useful for liquid precursors that are atomized in a carrier gas, in which case a second perforated plate in back of the showerhead face can be eliminated, thereby reducing the flow impedance and the required pressure of the liquid-entrained gas, which tends to deposit out at higher pressures. The reduced flow impedance is particularly useful for CVD of copper.

    摘要: Short POI titles are generated by removing unnecessary administrative area prefixes from existing POI titles and replacing necessary administrative area prefixes with shorter aliases. Administrative area prefixes are identified and analyzed to determine whether they are necessary. The analysis includes determining (1) whether the remainders with the prefixes excluded include a common suffix as a prefix, and (2) whether the remainders are unique in an applicable metropolis area. If a remainder does not include as a prefix a common suffix and is unique in the applicable metropolis area, the corresponding prefix is determined unnecessary and removed from the existing POI title to generate a short POI title. Otherwise, the corresponding prefix is determined necessary and replaced with a shorter alias to generate a short POI title.

    摘要: Embodiments of the invention provide apparatuses and methods for atomic layer deposition (ALD), such as plasma-enhanced ALD (PE-ALD). In some embodiments, a PE-ALD chamber is provided which includes a chamber lid assembly coupled with a chamber body having a substrate support therein. In one embodiment, the chamber lid assembly has an inlet manifold assembly containing an annular channel encompassing a centralized channel, wherein the centralized channel extends through the inlet manifold assembly, and the inlet manifold assembly further contains injection holes extending from the annular channel, through a sidewall of the centralized channel, and to the centralized channel. The chamber lid assembly further contains a showerhead assembly disposed below the inlet manifold assembly, a water box disposed between the inlet manifold assembly and the showerhead assembly, and a remote plasma system (RPS) disposed above and coupled with the inlet manifold assembly, and in fluid communication with the centralized channel.
