    摘要: A method of etching silicon oxide from a narrow trench and a wide trench (or open area) is described which allows the etch in the wide trench to progress further than the etch in the narrow trench. The method includes two dry etch cycles. The first dry etch cycle involves a low intensity or abbreviated sublimation step which leaves solid residue in the narrow trench. The remaining solid residue inhibits etch progress in the narrow trench during the second dry etch cycle allowing the etch in the wide trench to overtake the etch in the narrow trench.

    摘要: Aspects of the disclosure pertain to methods of depositing conformal silicon oxide multi-layers on patterned substrates. The conformal silicon oxide multi-layers are each formed by depositing multiple sub-layers. Sub-layers are deposited by flowing BIS(DIETHYLAMINO)SILANE (BDEAS) and an oxygen-containing precursor into a processing chamber such that a relatively uniform dielectric growth rate is achieved across the patterned substrate surface. A plasma treatment may follow formation of sub-layers to further improve conformality and to decrease the wet etch rate of the conformal silicon oxide multi-layer film. The deposition of conformal silicon oxide multi-layers grown according to embodiments have a reduced dependence on pattern density while still being suitable for non-sacrificial applications.

    摘要: A method for forming a multi-layer silicon oxide film on a substrate includes performing a deposition cycle that comprises depositing a silicon oxide layer using a thermal chemical vapor deposition (CVD) process and depositing a silicon oxide layer using a plasma enhanced chemical vapor deposition (PECVD) process. The deposition cycle is repeated a specified number of times to form the multi-layer silicon oxide film comprising a plurality of silicon oxide layers formed using the thermal CVD process and a plurality of silicon oxide layers formed using the PECVD process. Each silicon oxide layer formed using the thermal CVD process is adjacent to at least one silicon oxide layer formed using the PECVD process.

    摘要: Aspects of the disclosure pertain to methods of depositing conformal silicon oxide layers on patterned substrates. In embodiments, dielectric layers are deposited by flowing a silicon-containing precursor and ozone into a processing chamber such that a relatively uniform dielectric growth rate is achieved across the patterned substrate surface having heterogeneous materials and/or a heterogeneous pattern density distribution. The deposition of dielectric layers grown according to embodiments may have a reduced dependence on underlying material and pattern density while still being suitable for non-sacrificial applications. Reduction in dependence on pattern density is achieved by terminating deposition near the end of an incubation period. Multiple deposition cycles may be conducted in series since the beneficial nature of the incubation period may repeat after a pause in deposition.
