    摘要: Disclosed is a method of forming a thermal oxide film on a silicon single crystal wafer, which includes throwing the silicon single wafer into a heat treatment furnace; elevating temperature of the heat treatment furnace up to a temperature T1 where a thermal oxide film is formed to form a thermal oxide film having a thickness d1; subsequently lowering the temperature of the heat treatment furnace down to a temperature lower than the temperature T1; and thereafter elevating the temperature of the heat treatment furnace up to a temperature T2 higher than the temperature T1 to additionally form a thermal oxide film having a thickness d2 thicker than the thickness d1. Thus, there is provided a thermal oxide film formation method to suppress occurrence of slip dislocation and/or crack of the silicon single wafer during formation of the thermal oxide film.

    摘要: A method of forming a silicon oxide layer is described. The method first deposits a silicon-nitrogen-and-hydrogen-containing (polysilazane) film by radical-component chemical vapor deposition (CVD). The silicon-nitrogen-and-hydrogen-containing film is formed by combining a radical precursor (excited in a remote plasma) with an unexcited carbon-free silicon precursor. A capping layer is formed over the silicon-nitrogen-and-hydrogen-containing film to avoid time-evolution of underlying film properties prior to conversion into silicon oxide. The capping layer is formed by combining a radical oxygen precursor (excited in a remote plasma) with an unexcited silicon-and-carbon-containing-precursor. The films are converted to silicon oxide by exposure to oxygen-containing environments. The two films may be deposited within the same substrate processing chamber and may be deposited without breaking vacuum.

    摘要: The present invention belongs to the technical field of semiconductor materials and specifically relates to a method for cleaning & passivizing gallium arsenide (GaAs) surface autologous oxide and depositing an Al2O3 dielectric. This method includes: use a new-type of sulfur passivant to react with the autologous oxide on the GaAs surface to clean it and generate a passive sulfide film to separate the GaAs from the outside environment, thus preventing the GaAs from oxidizing again; further cleaning the residuals such as autologous oxides and sulfides on the GaAs surface through the pretreatment reaction of the reaction source trimethyl aluminum (TMA) of the Al2O3 ALD with the GaAs surface, and then deposit high-quality Al2O3 dielectric through ALD as the gate dielectric which fully separates the GaAs from the outside environment. The present invention features a simple process and good effects, and can provide preconditions for manufacturing the GaAs devices.

    摘要: Aspects of the disclosure pertain to methods of depositing dielectric layers on patterned substrates. In embodiments, dielectric layers are deposited by flowing BIS(DIETHYLAMINO)SILANE (BDEAS), ozone and molecular oxygen into a processing chamber such that a relatively uniform dielectric growth rate is achieved across the patterned substrate surface. The deposition of dielectric layers grown according to embodiments may have a reduced dependence on pattern density while still being suitable for non-sacrificial applications.
