摘要:
Etching gases are disclosed for plasma etching channel holes, gate trenches, staircase contacts, capacitor holes, contact holes, etc., in Si-containing layers on a substrate and plasma etching methods of using the same. The etching gases are trans-1,1,1,4,4,4-hexafluoro-2-butene; cis-1,1,1,4,4,4-hexafluoro-2-butene; hexafluoroisobutene; hexafluorocyclobutane (trans-1,1,2,2,3,4); pentafluorocyclobutane (1,1,2,2,3-); tetrafluorocyclobutane (1,1,2,2-); or hexafluorocyclobutane (cis-1,1,2,2,3,4). The etching gases may provide improved selectivity between the Si-containing layers and mask material, less damage to channel region, a straight vertical profile, and reduced bowing in pattern high aspect ratio structures.
摘要:
Disclosed are compounds for plasma ashing photoresist layers on a substrate and methods of using the same. The plasma ashing compounds induce limited to no damage to the underlying layer, such as the low-k film layer.
摘要:
Disclosed are processes for the use of bis-ketoiminate copper precursors for the deposition of copper-containing films via Plasma Enhanced Atomic Layer Deposition (PEALD) or Plasma Enhanced Chemical Vapor Deposition (PECVD).
摘要:
The present invention relates to a process for the use of Titanium amidinate metal precursors for the deposition of Titanium-containing films via Plasma Enhanced Atomic Layer Deposition (PEALD) or Plasma Enhanced Chemical Vapor Deposition (PECVD).

摘要:
Compositions and methods for forming a metal-containing thin film on a substrate. A reactor and at least one substrate in the reactor are provided. A metal-containing bis-β-diketiminate precursor is introduced into the reactor. The reactor is maintained at a set temperature and pressure, and the precursor is contacted with the substrate to form a metal-containing film on the substrate.

摘要:
Disclosed are hafnium- and zirconium-containing precursors and methods of providing the same. The disclosed precursors include a ligand and at least one aliphatic group as substituent selected to have greater degrees of freedom than the usual substituents. The disclosed precursors may be used to deposit hafnium- or zirconium-containing layers using vapor deposition methods such as chemical vapor deposition or atomic layer deposition.
摘要:
The disclosure relates to a process for depositing a Manganese-containing film comprising the step of providing a metal guanidinate and/or metal amidinate precursor, suitable for plasma deposition at temperature equal or lower than 500 degrees C., to a plasma deposition process comprising a deposition temperature equal or lower than 500 degrees C.
