    摘要: A programmable storage element for redundancy-programing includes a programmable antifuse circuit, which includes a plurality of first resistors and a switching circuit for coupling the first resistors in series in response to a plurality of first control signals and for coupling the first resistors in parallel in response to a plurality of second control signals to permit programing of the first resistors, and a sensing circuit for determining whether or not the first resistors have been programmed. The state of the first resistors is determined by comparing a first voltage drop across the first resistors with a second voltage drop across a second resistor. Each of the first resistors is an unsilicided polysilicon conductor which has an irreversible resistance decrease when a predetermined threshold current is applied for a minimum period of time.

    摘要: The disclosure describes an integrated circuit with multiple semiconductor fins having different widths and variable spacing on the same substrate. The method of forming the circuit incorporates a sidewall image transfer process using different types of mandrels. Fin thickness and fin-to-fin spacing are controlled by an oxidation process used to form oxide sidewalls on the mandrels, and more particularly, by the processing time and the use of intrinsic, oxidation-enhancing and/or oxidation-inhibiting mandrels. Fin thickness is also controlled by using sidewalls spacers combined with or instead of the oxide sidewalls. Specifically, images of the oxide sidewalls alone, images of sidewall spacers alone, and/or combined images of sidewall spacers and oxide sidewalls are transferred into a semiconductor layer to form the fins. The fins with different thicknesses and variable spacing can be used to form a single multiple-fin FETs.

    摘要: Methods for fabricating a device structure for use as a memory cell in a non-volatile random access memory. The method includes forming first and second semiconductor bodies on the insulating layer that have a separated, juxtaposed relationship, doping the first semiconductor body to form a source and a drain, and partially removing the second semiconductor body to define a floating gate electrode adjacent to the channel of the first semiconductor body. The method further includes forming a first dielectric layer between the channel of the first semiconductor body and the floating gate electrode, forming a second dielectric layer on a top surface of the floating gate electrode, and forming a control gate electrode on the second dielectric layer that cooperates with the floating gate electrode to control carrier flow in the channel in the first semiconductor body.

    摘要: In one embodiment, a second metal line embedded in a second dielectric layer overlies a first metal line embedded in a first dielectric layer. A portion of the second dielectric layer overlying the first metal line is recessed employing a photoresist and the second metal line as an etch mask. A doped semiconductor spacer is formed within the recess to provide a resistive link between the first metal line and the second metal line. In another embodiment, a first metal line and a second metal line are embedded in a dielectric layer. An area of the dielectric layer laterally abutting the first and second metal lines is recessed employing a photoresist and the first and second metal lines as an etch mask. A doped semiconductor spacer is formed on sidewalls of the first and second metal lines, providing a resistive link between the first and second metal lines.

    摘要: A voltage divider for integrated circuits that does not include the use of resistors. In one embodiment, voltage node VDD is connected with two n-type transistors, NFET1 and NFET2, which are connected in series. NFET 1 includes a source (12), a drain (14), a gate electrode (16) having a gate area A1 (not shown), and a p-substrate (18). NFET2 includes a source (20), a drain (22), a gate electrode (24) having a gate area A2 (not shown), and a p-substrate (26). Source (12) and drain (14) of NFET1 are coupled with gate electrode (24) of NFET2. The voltage difference between NFET1 and NFET2 has a linear function with VDD. As a result, voltage VDD may be divided between NFET1 and NFET2 by properly choosing the ratio between each of the respective transistor gate electrode areas, (A1) and (A2).

    摘要: An inverse-T transistor is formed by a method that decouples the halo implant, the deep S/D implant and the extension implant, so that the threshold voltage can be set by adjusting the halo implant without being affected by changes to the extension implant that are intended to alter the series resistance of the device. Formation of the inverse-T structure can be made by a damascene method in which a temporary layer deposited over the layer that will form the cross bar of the T has an aperture formed in it to hold the gate electrode, the aperture being lined with vertical sidewalls that provide space for the ledges that form the T. Another method of gate electrode formation starts with a layer of poly, forms a block for the gate electrode, covers the horizontal surfaces outside the gate with an etch-resistant material and etches horizontally to remove material above the cross bars on the T, the cross bars being protected by the etch resistant material.
