Patent number: 8980382Abstract: Methods of forming silicon oxide layers are described. The methods include the steps of concurrently combining both a radical precursor and a radical-oxygen precursor with a carbon-free silicon-containing precursor. One of the radical precursor and the silicon-containing precursor contain nitrogen. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate.

Patent number: 6673722Abstract: An improved chemical vapor deposition or etching is shown in which cyclotron resonance and photo or plasma CVD cooperate to deposit a layer with high performance at a high deposition speed. The high deposition speed is attributed to the cyclotron resonance while the high performance is attributed to the CVDs.Type: GrantFiled: May 9, 1997Date of Patent: January 6, 2004Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Shunpei Yamazaki

Patent number: 6653245Abstract: A method for liquid phase deposition, including the steps of providing at least two raw materials from at least two supply devices of a saturation reaction system into a mixture trough and stirring until saturation occurs, filtering out unnecessary solid-state particles, and providing saturated and filtered liquid into an over-saturation reaction trough of a steady-flow over-saturation loop reaction system and stopping the saturated and filtered liquid when the over-saturation reaction trough is filled and the saturated and filtered liquid over-flows into a liquid level control trough to a pre-determined level. The method also includes the steps of providing a substrate in the over-saturation reaction trough, providing reactants from at least two supply devices into the over-saturation reaction trough, and depositing a thin film onto the substrate when the saturated liquid becomes over-saturated.Type: GrantFiled: June 6, 2001Date of Patent: November 25, 2003Assignee: Industrial Technology Research InstituteInventors: Muh-Wang Liang, Pang-Min Chiang, Chen Max, Jen-Rong Huang, Ching-Fa Yeh

Patent number: 6616985Abstract: An apparatus and method for injecting gas within a plasma reactor and tailoring the distribution of an active species generated by the remote plasma source over the substrate or wafer. The distribution may be uniform, wafer-edge concentrated, or wafer-center concentrated. A contoured plate or profiler modifies the distribution. The profiler is an axially symmetric plate, having a narrow top end and a wider bottom end, shaped to redistribute the gas flow incident upon it. The method for tailoring the distribution of the active species over the substrate includes predetermining the profiler diameter and adjusting the profiler height over the substrate.Type: GrantFiled: July 2, 2001Date of Patent: September 9, 2003Assignee: Novellus Systems, Inc.Inventors: Ronald Allan Powell, Gabriel I.

Patent number: 6616986Abstract: The present invention provides for sequential chemical vapor deposition by employing a reactor operated at low pressure, a pump to remove excess reactants, and a line to introduce gas into the reactor through a valve. A first reactant forms a monolayer on the part to be coated, while the second reactant passes through a radical generator which partially decomposes or activates the second reactant into a gaseous radical before it impinges on the monolayer. This second reactant does not necessarily form a monolayer but is available to react with the monolayer. A pump removes the excess second reactant and reaction products completing the process cycle. The process cycle can be repeated to grow the desired thickness of film.Type: GrantFiled: October 9, 2001Date of Patent: September 9, 2003Assignee: ASM America Inc.Inventor: Arthur Sherman

Patent number: 6607790Abstract: The present invention relates to a plasma-enhanced chemical vapor deposition (PECVD) method of depositing a thin layer of a material, such as silicon dioxide, on the surface of a body, such as a semiconductor substrate. The method includes forming in a deposition chamber a plasma by means of two electrical power sources of different frequencies. A reaction gas is admitted into the deposition chamber and subjected to the plasma. The reaction gas is a mixture of tetraethylorthosilicate and a halogen gas, such as a gas of fluorine, chlorine or bromine. The reaction gas is reacted by the plasma to cause the material of the gas to deposit on the body which is within the chamber. This results in a deposited layer having a smoothly tapered surface even when the surface of the body possesses valleys and mesas, and thus prevents the formation of voids.Type: GrantFiled: July 7, 1997Date of Patent: August 19, 2003Assignee: Applied Materials, Inc.Inventor: Katsuyuki Musaka

Patent number: 6436487Abstract: In a film deposition process wherein a plasma generation chamber is divided from a deposition chamber, radicals are extracted from the plasma generation chamber to the deposition chamber and caused to react with a process gas to form a silicon oxide film. The deposition apparatus has a host controller for dictating a pattern of control of the process gas flow to an MFC provided in a feed part for feeding the process gas into the deposition chamber. The host controller gives the MFC instructions for executing control to, in a first half side time constituting not more than half of the whole film deposition time, first make zero or limit and then gradually increase the process gas flow. The process gas flow in the first half side time can also be limited so that the thickness of film deposited in the first half side time is not greater than 10% of the overall thickness of the silicon oxide film. A silicon-hydrogen compound (SinH2n+2 (n=1, 2, 3, . . . )) is used as the process gas.Type: GrantFiled: July 6, 2000Date of Patent: August 20, 2002Assignees: Anelva Corporation, NEC CorporationInventors: Manabu Ikemoto, Katsuhisa Yuda
