摘要:
An ultra low k dielectric film, including a silicon film containing porosity deriving from a porogen, as formed from a precursor silane and a porogen, wherein the precursor silane has a water content below 10 ppm, based on total weight of the precursor silane, and/or the porogen has a water content below 10 ppm, based on total weight of the porogen. In one implementation, the precursor silane is diethoxymethylsilane, and the porogen is bicyclo[2.2.1]-hepta-2,5-diene having a trace water content below 10 ppm, based on total weight of said bicyclo[2.2.1]-hepta-2,5-diene. These super-dry reagents are unexpectedly polymerization-resistant during their delivery and deposition in the formation of ultra low k films, and are advantageously employed to produce ultra low k films of superior character.
摘要:
Antimony, germanium and tellurium precursors useful for CVD/ALD of corresponding metal-containing thin films are described, along with compositions including such precursors, methods of making such precursors, and films and microelectronic device products manufactured using such precursors, as well as corresponding manufacturing methods. The precursors of the invention are useful for forming germanium-antimony-tellurium (GST) films and microelectronic device products, such as phase change memory devices, including such films.
摘要:
Precursors for use in depositing tellurium-containing films on substrates such as wafers or other microelectronic device substrates, as well as associated processes of making and using such precursors, and source packages of such precursors. The precursors are useful for deposition of chalcogenide thin films in the manufacture of nonvolatile Phase Change Memory (PCM), by deposition techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD).

摘要:
A system and method for forming a phase change memory material on a substrate, in which the substrate is contacted with precursors for a phase change memory chalcogenide alloy under conditions producing deposition of the chalcogenide alloy on the substrate, at temperature below 350° C., with the contacting being carried out via chemical vapor deposition or atomic layer deposition. Various tellurium, germanium and germanium-tellurium precursors are described, which are useful for forming GST phase change memory films on substrates.
