  • Patent number: 7888252
    Abstract: A method of forming contacts for semiconductor devices, the method including depositing an inter-level dielectric (ILD) over a plurality of gate stacks, in which the divots within the inter-level dielectric layer are defined by the spaces between the gate stacks, filling the divots with an initial fill material, depositing a masking material on the dielectric over the gate stacks, and selectively etching the fill material to form contact vias. The fill material may be a self-assembly material such as a multi-block copolymer in which the blocks self organize vertically within the divots, so that a selective etch of the block material will remove the vertically organized blocks from the divot, but leave at least one block over the gate regions. In another embodiment, the fill material may be a metal, and the masking material may be a parylene based polymer.

  • Patent number: 7783998
    Abstract: A solution for prototyping electronic devices is proposed. The solution uses a carrier which allows mounting the desired components with different configurations. In order to achieve this result, for some of these components, such as discrete capacitors, the carrier includes more contacts than the corresponding terminals. In this way, each capacitor may be mounted in multiple positions (such as a working one based on the manufacturing standards, an advanced one with gaps between the components below the corresponding safety margins, and as control one with larger gaps). As a result, it is possible to assemble different prototypes by using a single type of carrier, thereby substantially reducing the cost of the process.

  • Patent number: 7767537
    Abstract: Trench capacitors having small and large sizes can be formed simultaneously using a combined lithography process in which openings in a photomask have the same dimensions and spacings. Larger capacitors are formed when the openings in the photomask are aligned with one crystal plane of the semiconductor substrate causing the resulting trenches in the semiconductor substrate to merge. Smaller capacitors are formed when the openings in the photomask are aligned with another crystal plane of the semiconductor substrate in which case each trench remains separate from other trenches.

  • Patent number: 7645700
    Abstract: A method and structure for a composite stud contact interface with a decreased contact resistance and improved reliability. A selective dry etch is used which comprises a fluorine containing gas. The contact resistance is reduced by partially dry-etching back the tungsten contact after or during the M1 RIE process. The recessed contact is then subsequently metalized during the M1 liner/plating process. The tungsten contact height is reduced after it has been fully formed.

Each time a subscription request for a notification service related to the received content description is received from an end user, keywords values and the delivery channels selected by the user are recorded. A notification rule associated with the end user based on the selected keyword values and the localization of the selected keyword values in the content is generated. Each time a piece of content related to the content description is received from the content provider, the received piece of content is adapted to comply with the generated rules. For each rule previously generated, the values contained in the adapted piece of content are checked against the values as defined in the rule for each localization.

  • Patent number: 7442611
    Abstract: A method is provided for fabricating a semiconductor device structure. In such method a p-type field effect transistor (PFET) and an n-type field effect transistor (NFET), each of the NFET and the PFET having a conduction channel disposed in a single-crystal semiconductor region of a substrate. A stressed film having a compressive stress at a first magnitude can be formed to overlie the PFET and the NFET. Desirably, a mask is formed to cover the PFET while exposing the NFET, after which, desirably, a portion of the stressed film overlying the NFET is subjected to ion implantation, while the mask protects another portion of the stressed film overlying the PFET from the ion implantation. The substrate can then be annealed, whereby, desirably, the compressive stress of the implanted portion of the stressed film is much reduced from the first magnitude by the annealing.

  • Patent number: 7437352
    Abstract: Information is typically obtained from a relational database using a query in structured query language (SQL). An extension to the SQL standard is described which permits plotting the results of a query. SQL keywords are provided for specifying a format for graphing selected data, and syntax for recognizing those keywords, thereby causing the data to be presented as a graph according to the specified format. This extension of SQL maintains the syntax and style of conventional SQL queries. This permits automated systems, such as database driven websites, to issue extended SQL queries directly to a relational database and have the results returned as formatted graphical content.
