Patent number: 7557008Abstract: A method forms a nonvolatile memory device using a semiconductor substrate. A charge storage layer is formed overlying the semiconductor substrate and a layer of gate material is formed overlying the charge storage layer to form a control gate electrode. A protective layer overlies the layer of gate material. Dopants are implanted into the semiconductor substrate and are self-aligned to the control gate electrode on at least one side of the control gate electrode to form a source and a drain in the semiconductor substrate on opposing sides of the control gate electrode. The protective layer prevents the dopants from penetrating into the control gate electrode. The protective layer that overlies the layer of gate material is removed. Electrical contact is made to the control gate electrode, the source and the drain. In one form a select gate is also provided in the memory device.Type: GrantFiled: January 23, 2007Date of Patent: July 7, 2009Assignee: Freescale Semiconductor, Inc.Inventors: Rajesh Rao, Ramachandran Muralidhar

Publication number: 20080134237Abstract: A TV-set is equipped with HDMI and USB connections that allow it to display and run audio-video content from a variety of conventional consumer devices. The TV-set is further equipped to provide a secure HDMI-USB interface that will allow the transfer of licensed high definition content and Internet subscriber services. Such secure HDMI-USB interface also enables a selection of proprietary application modules to be attached. Downloadable user interface templates, much like XML style sheets, are rendered to a user interface displayed on the screen. These are associated with corresponding thumbnails and URI's that allow a user to surf through lists and catalogs of materials, and then to play them in the appropriate formats and provide the machine with a customized controller. A remote commander is simplified, yet expanded to control all the attached devices through interactions with the user interface.Type: ApplicationFiled: August 16, 2007Publication date: June 5, 2008Applicants: SONY CORPORATION, SONY ELECTRONICS, INC.Inventors: Edgar Tu, David Boyden, Takashi Hironaka, Thomas Dawson, George Williams, Ludovic Douillet, Rajesh Rao, Peter Rae Shintani, Djung Nguyen, Milton Frazier, Ian Charles Matthews, Behram Mario Dacosta, Robert Hardacker, Nicholas James Colsey, Mark Hanson, Jason R.

Publication number: 20070202708Abstract: An insulating layer formed by deposition is annealed in the presence of radical oxygen to reduce bond defects. A substrate is provided. An oxide layer is deposited overlying the substrate. The oxide layer has a plurality of bond defects. The oxide layer is annealed in the presence of radical oxygen to modify a substantial portion of the plurality of bond defects by using oxygen atoms. The anneal, in one form, is an in-situ steam generation (ISSG) anneal. In one form, the insulating layer overlies a layer of charge storage material, such as nanoclusters, that form a gate structure of a semiconductor storage device. The ISSG anneal repairs bond defects by oxidizing defective silicon bonds in the oxide layer when the oxide layer is silicon dioxide.Type: ApplicationFiled: February 28, 2006Publication date: August 30, 2007Inventors: Tien Luo, Rajesh Rao

Publication number: 20070082495Abstract: A semiconductor device includes a plurality of pillars formed from a conductive material. The pillars are formed by using a plurality of nanocrystals as a hardmask for patterning the conductive material. A thickness of the conductive material determines the height of the pillars. Likewise, a width of the pillar is determined by the diameter of a nanocrystal. In one embodiment, the pillars are formed from polysilicon and function as the charge storage region of a non-volatile memory cell having good charge retention and low voltage operation. In another embodiment, the pillars are formed from a metal and function as a plate electrode for a metal-insulator-metal (MIM) capacitor having an increased capacitance without increasing the surface area of an integrated circuit.Type: ApplicationFiled: October 6, 2005Publication date: April 12, 2007Inventors: Leo Mathew, Rajesh Rao, Ramachandran Muralidhar

Publication number: 20070077743Abstract: A FinFET includes a plurality of semiconductor fins. Over a semiconductor layer, patterned features (e.g. of minimum photolithographic size and spacing) are formed. In one example of fin formation, a first set of sidewall spacers are formed adjacent to the sides of these patterned features. A second set of sidewall spacers of a different material are formed adjacent to the sides of the first set of sidewall spacers. The first set of sidewall spacers are removed leaving the second set of sidewall spacers spaced from the patterned features. Both the second set of sidewall spacers and the patterned features are used as a mask to an etch that leaves semiconductor fins patterned as per the second set of sidewall spacers and the patterned features. These resulting semiconductor fins, which have sub-lithographic spacings, are then used for channels of a FinFET transistor.Type: ApplicationFiled: September 30, 2005Publication date: April 5, 2007Inventors: Rajesh Rao, Leo Mathew

Publication number: 20060211206Abstract: A process for forming an electronic device can be performed, such that as little as one gate electric layer may be formed within each region of the electronic device. In one embodiment, the electronic device can include an NVM array and other regions that have different gate dielectric layers. By protecting the field isolation regions within the NVM array and other regions while gate dielectric layer are formed, the field isolation regions may be exposed to as little as one oxide etch between the time any of the gate dielectric layers are formed the time such gate dielectric layers are covered by gate electrode layers. The process helps to reduce field isolation erosion and reduce problems associated therewith.Type: ApplicationFiled: March 18, 2005Publication date: September 21, 2006Applicant: Freescale Semiconductor, Inc.Inventors: Rajesh Rao, Ramachandran Muralidhar

Publication number: 20060194438Abstract: A plurality of memory cell devices is formed by using an intermediate dual polysilicon-nitride control electrode stack overlying nanoclusters. The stack includes a first-formed polysilicon-nitride layer and a second-formed polysilicon-containing layer. The second-formed polysilicon-containing layer is removed from areas containing the plurality of memory cells. In one form the second-formed polysilicon-containing layer also contains a nitride portion which is also removed, thereby leaving the first-formed polysilicon-nitride layer for the memory cell devices. In another form the second-formed ploysilicon-containing layer does not contain nitride and a nitride portion of the first-formed polysilicon-nitride layer is also removed. In the latter form a subsequent nitride layer is formed over the remaining polysilicon layer. In both forms a top portion of the device is protected from oxidation, thereby preserving size and quality of underlying nanoclusters.Type: ApplicationFiled: June 25, 2004Publication date: August 31, 2006Inventors: Rajesh Rao, Ramachandran Muralidhar, Robert Steimle, Gowrishankar Chindalore
