  • Patent number: 8008725
    Abstract: A field transistor for electrostatic discharge (ESD) protection and method for making such a transistor is described. The field transistor includes a gate conductive layer pattern formed on a field oxide layer. Since the gate conductive layer pattern is formed on the field oxide layer, a thin gate insulating layer having a high possibility of insulation breakdown is not used. To form an inversion layer for providing a current path between source and drain regions, a field oxide layer is interposed to form low concentration source and drain regions overlapped by the gate conductive layer pattern.

  • Patent number: 8004034
    Abstract: Embodiments relate to a single poly type EEPROM and a method for manufacturing an EEPROM. According to embodiments, a single poly type EEPROM may include unit cells. A unit cell may include a floating gate at a side of a control node formed on and/or over a semiconductor substrate having an activation region and a device isolation area, not overlapping a device isolation region but overlapping only a top of the activation region. A select gate may be formed on and/or over a top of the activation region. According to embodiments, a ratio of a capacitance of a control node side to a capacitance of a bit line side may increase, which may improve a coupling ratio. According to embodiments, a junction capacitance may be maximized by not doping the floating gate with an impurity, which may allow for a reduction in chip size by securing design margins.

  • Patent number: 7999377
    Abstract: The process begins with separate device wafers having complimentary chips. Thin metal capture pads, having a preferred thickness of about 10 microns so that substantial pressure may be applied during processing without damaging capture pads, are deposited on both device wafers, which are then tested and mapped for good chip sites. A handle wafer is attached to one device wafer, which can then be thinned to improve via etching and filling. Capture pads are removed and replaced after thinning. The device wafer with handle wafer is diced, and good chips with attached portions of the diced handle wafer are positioned and bonded to the good chip sites of the other device wafer, and the handle wafer portions are removed. The device wafer having known good 3-D chips then undergoes final processing.

  • Patent number: 7994604
    Abstract: One embodiment of the present invention provides a system that facilitates reducing the power needed for proximity communication. This system includes an integrated circuit with an array of transmission pads that transmit a signal using proximity communication. A layer of fill metal is located in proximity to this array of transmission pads, wherein the layer of fill metal is “floating” (e.g., not connected to any signal). Leaving this layer of fill metal floating reduces the parasitic capacitance for the array of transmission pads, which can reduce the amount of power needed to transmit the signal.
