Patent number: 7482267Abstract: A spin on glass SOG layer 30 is formed, then a PECVD barrier layer 40 over the SOG layer. Holes 50 in the SOG layer for vias are formed with a wine glass profile, so that in a peripheral region around the periphery of the holes, the barrier layer is thinner or absent, and ion implantation is performed substantially perpendicular to the layers, to reach the SOG layer through the barrier layer preferentially in the peripheral region. This enables the implantation to be concentrated on the peripheral region, without the need for implantation at a high angle and wafer rotation. This enables the manufacturing process to be simplified and hence costs reduced. By concentrating the implantation in the peripheral region where it can reduce moisture transfer to material in the holes, there is less risk of deplanarization due to the SOG shrinkage associated with ion implantation.Type: GrantFiled: April 21, 2006Date of Patent: January 27, 2009Assignee: AMI Semiconductor Belgium BVBAInventor: Peter Coppens

Patent number: 7468317Abstract: A method of forming a metal line, in which a nitride layer is used instead of a metal barrier layer, enabling a metal line structure with a relatively low resistance and therefore realizing a high integration of a device. In the method of forming the metal line of the semiconductor device, a first insulating layer and a second insulating layer with a different etch selectivity are sequentially formed on a semiconductor substrate. Predetermined regions of the first insulating layer and the second insulating layer are sequentially etched to form a contact hole. A metal barrier layer is formed on the entire surface including the contact hole. A first metal material is deposited on the entire surface to gap-fill the contact hole. The first metal material on the second insulating layer is stripped such that the first metal material remains only within the contact hole, thus forming a contact plug. A metal line is formed on a predetermined region of the second insulating layer including the contact plug.Type: GrantFiled: November 7, 2006Date of Patent: December 23, 2008Assignee: Hynix Semiconductor Inc.Inventors: Jik Ho Cho, Tae Kyung Kim

Patent number: 7387926Abstract: A method for manufacturing a CMOS image sensor is provided. The method includes forming a gate electrode on a semiconductor layer having defined regions of a photodiode region and a logic region, such that a gate oxide film is interposed between the semiconductor layer and the gate electrode; forming sidewall insulating films at both sides of the gate electrode, followed by forming a salicide-preventing film over an overall surface of the gate electrode and insulating films; removing the salicide-preventing film formed in the logic region; and removing a portion of the sidewall insulating films exposed by removing the salicide-preventing film, thereby exposing an upper side surface of the gate electrode.Type: GrantFiled: June 9, 2005Date of Patent: June 17, 2008Assignee: Dongbu Electronics Co., Ltd.Inventor: Chang Hun Han

Patent number: 7351643Abstract: Even though photolithography with a diameter of 0.20 ?m or less is employed, a contact hole having a tapered shape with a required width including a positioning tolerance can be formed in a narrower gap between the gate electrodes. A method forms a minute contact hole between gate electrodes of a semiconductor device, which has a silicon dioxide film disposed at an upper layer of the semiconductor device and a BPSG film disposed below the silicon dioxide film. The BPSG film has gate electrodes therein, and no silicon nitride film is disposed on top and side surfaces of the gate electrodes, and no silicon nitride film is disposed above the gate electrodes. The silicon dioxide film is etched by a mixed gas of CF4, O2 and Ar at a substrate temperature of at least 40° C. The BPSG film is etched by over-etching of the silicon dioxide film so that a W-like shape is formed in the BPSG film.Type: GrantFiled: March 9, 2006Date of Patent: April 1, 2008Assignee: Oki Electric Industry Co., Ltd.Inventor: Takeshi Nagao

Patent number: 7297620Abstract: In methods of forming an oxide layer and an oxynitride layer, a substrate is loaded into a reaction chamber having a first pressure and a first temperature. The oxide layer is formed on the substrate using a reaction gas while increasing a temperature of the reaction chamber from the first temperature to a second temperature under a second pressure. Additionally, the oxide layer is nitrified in the reaction chamber to form the oxynitride layer on the substrate. When the oxide layer and/or the oxynitride layer are formed on the substrate, minute patterns of a semiconductor device, for example a DRAM device, an SRAM device or an LOGIC device may be easily formed on the oxide layer or the oxynitride layer.Type: GrantFiled: May 6, 2004Date of Patent: November 20, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Young-Sub You, Hun-Hyeoung Leam, Seok-Woo Nam, Bong-Hyun Kim, Woong Lee, Sang-Hoon Lee

Patent number: 7223706Abstract: A method of forming a plasma enhanced deposited oxide film on a substrate includes introducing into a chamber containing the substrate silane gas and a dopant gas such as phosphine. The chamber is pressurized and energy is applied to create a plasma. The energy may be a dual frequency energy. The gas rates and pressure are selected to produce a plasma enhanced deposited oxide film on a substrate having a Si—O—Si bond peak absorbance in the IR spectrum of at least 1092 cm?1.Type: GrantFiled: September 30, 2004Date of Patent: May 29, 2007Assignee: Intersil Americas, Inc.Inventors: Katie H. Pentas, Mark D. Bordelon, Jack H. Linn

Patent number: RE40507Abstract: A method of forming a pre-metal dielectric film having good as deposited gapfill characteristics, as well as good mobile-ion gettering capability. The method involves first depositing a layer of high-ozone undoped silicon dioxide film having a high ozone/TEOS volume ratio. Then, a low-ozone doped BPSG film is deposited over the high-ozone undoped silicon dioxide layer. The film layers are heat treated to densify the film, and then the top layer is planarized using known planarization techniques to a thickness that allows for adequate mobile-ion gettering.Type: GrantFiled: June 25, 2003Date of Patent: September 16, 2008Assignee: Atmel CorporationInventors: Amit S. Kelkar, Michael D. Whiteman
