  • Patent number: 12675044
    Abstract: The invention provides certain mixed Sn (II) amide/alkoxide precursor compounds. These compounds are useful in precursor compositions in the vapor deposition of tin-containing films such as tin oxide films onto a surface of a microelectronic device. These precursor compounds are useful in, for example, extreme ultraviolet light (EUV) lithography techniques used in microelectronic device manufacturing when paired with certain counter-reactants in a vapor deposition process. In this process, the resulting organotin polymeric surface is thus EUV-patternable insofar as when exposed to a patterned beam of EUV light, exposed portions are subjected to further reaction, thus creating regions which are chemically and physically different; this difference enables further processing and lithography of exposed regions and/or non-exposed regions and lithography in pursuit of the ultimate fabricated microelectronic device.

  • Patent number: 12674097
    Abstract: The invention provides compositions useful in the etching of polysilicon in the presence of silicon oxide and silicon nitride. The compositions comprise choline hydroxide, an oxidizing agent such as periodic acid, and optionally a surfactant, and are useful in the etching of polysilicon in general, and in particular in both the operation of polysilicon trim as well as polysilicon exhume. The utilization of an added oxidizing agent was found to reduce selectivity of silicon etching based on the silicon crystal orientation, which was found to reduce roughness and the presence of residual silicon residues, such as silicon (111) residues after the etching step.

  • Patent number: 12668502
    Abstract: The invention provides a process for preparing molybdenum and tungsten oxyhalide compounds which are useful in the deposition of molybdenum and tungsten containing films on various surfaces of microelectronic devices. In the process of the invention, a molybdenum or tungsten trioxide is heated in either a solid state medium or in a melt-phase reaction comprising a eutectic blend comprising alkaline and/or alkaline earth metal salts. The molybdenum or tungsten oxyhalides thus formed may be isolated as a vapor and crystallized to provide highly pure precursor compounds such as MoO2Cl2.

  • Patent number: 12672491
    Abstract: The use of selective deposition of silicon nitride can eliminate conventional patterning steps by allowing silicon nitride to be deposited only in selected and desired areas. Using a silicon iodide precursor alternately with a thermal nitrogen source in an ALD or pulsed CVD mode, silicon nitride can be deposited preferentially on a surface such as silicon nitride, silicon dioxide, germanium oxide, SiCO, SiOF, silicon carbide, silicon oxynitride, and low k substrates, while exhibiting very little deposition on exposed surfaces such as titanium nitride, tantalum nitride, aluminum nitride, hafnium oxide, zirconium oxide, aluminum oxide, titanium oxide, tantalum oxide, niobium oxide, lanthanum oxide, yttrium oxide, magnesium oxide, calcium oxide, and strontium oxide.
