  • Patent number: 7768041
    Abstract: A field effect transistor (“FET”) is provided which includes an active semiconductor region including a channel region, a first source-drain region and a second source-drain region. A major surface of the active semiconductor region is divided into a mutually exclusive first portion and a second portion. A first liner applies a first stress to the first portion of the major surface, and a second liner applies a second stress to the second portion of the major surface. The first and second stresses are each selected from high tensile stress, high compressive stress and neutral stress, with the first stress being different from the second stress. The liners can help to differentiate a first operating current conducted by the first portion of the FET under one operating condition and a second operating current that is conducted by the second portion of the FET under a different operating condition.

  • Patent number: 7723741
    Abstract: Methods of packaging microelectronic imagers and packaged microelectronic imagers. An embodiment of such a method can include providing an imager workpiece having a plurality of imager dies arranged in a die pattern and providing a cover substrate through which a desired radiation can propagate. The imager dies include image sensors and integrated circuitry coupled to the image sensors. The method further includes providing a spacer having a web that includes an adhesive and has openings arranged to be aligned with the image sensors. For example, the web can be a film having an adhesive coating, or the web itself can be a layer of adhesive. The method continues by assembling the imager workpiece with the cover substrate such that (a) the spacer is between the imager workpiece and the cover substrate, and (b) the openings are aligned with the image sensors. The attached web is not cured after the imager workpiece and the cover substrate have both been adhered to the web.

  • Patent number: 7605411
    Abstract: An HCCD includes a channel 21 that transfers electric charges in an X direction, a channel 25 that transfers the electric charges in a Z1 direction, a channel 23 that transfers the electric charges in a Z2 direction, and a channel 22 that connects the channels 23, 25 to the channel 21. The following relation is satisfied in impurity concentration of the channels: channel 21 channel 22 channel 23, 25. A fixed DC voltage is applied to branch electrodes 12a, 12b above the channel 22. The channel 22 has protrusion portions 19 that protrude inward from an outer circumference, which connects T1 and T2, and an outer circumference, which connects T3 and T4. The protrusion portions 19 causes charges below the transfer electrode 11b to move near the center of the channel 22 in a Y direction. Thereby, the travel distance of the charges in the channel 22 is reduced.

    Abstract: Provided are a doping mask and methods of manufacturing a charge transfer image device and a microelectronic device using the same. The method includes forming a photoresist film on an entire surface of a substrate or sub-substrate having a peripheral circuit region and a pixel region, removing the photoresist film on an upper surface of the substrate intended for the peripheral circuit region and patterning the photoresist film on an upper surface of the substrate intended for the pixel region to form a photoresist pattern having an array of openings with a predetermined pitch, implanting ions at the same concentration level into the entire surface of the substrate using the photoresist pattern as a doping mask, and diffusing the implanted ions by annealing. The pitch is determined so that ions implanted through each opening diffuse toward those implanted through an adjacent one to form wells.

  • Patent number: 7460852
    Abstract: An RF switch circuit and method for switching RF signals that may be fabricated using common integrated circuit materials such as silicon, particularly using insulating substrate technologies. The RF switch includes switching and shunting transistor groupings to alternatively couple RF input signals to a common RF node, each controlled by a switching control voltage (SW) or its inverse (SW_), which are approximately symmetrical about ground. The transistor groupings each comprise one or more insulating gate FET transistors connected together in a “stacked” series channel configuration, which increases the breakdown voltage across the series connected transistors and improves RF switch compression. A fully integrated RF switch is described including control logic and a negative voltage generator with the RF switch elements. In one embodiment, the fully integrated RF switch includes an oscillator, a charge pump, CMOS logic circuitry, level-shifting and voltage divider circuits, and an RF buffer circuit.
