  • Patent number: 7772643
    Abstract: A method of fabricating a semiconductor device having a metal gate pattern is provided in which capping layers are used to control the relative oxidation rates of portions of the metal gate pattern during a oxidation process. The capping layer may be a multilayer structure and may be etched to form insulating spacers on the sidewalls of the metal gate pattern. The capping layer(s) allow the use of a selective oxidation process, which may be a wet oxidation process utilizing partial pressures of both H2O and H2 in an H2-rich atmosphere, to oxidize portions of the substrate and metal gate pattern while suppressing the oxidation of metal layers that may be included in the metal gate pattern. This allows etch damage to the silicon substrate and edges of the metal gate pattern to be reduced while substantially maintaining the original thickness of the gate insulating layer and the conductivity of the metal layer(s).

  • Patent number: 7768097
    Abstract: An integrated circuit package includes an inductance loop formed from a connection of lead wires and one or more input/output (I/O) package pins. In one embodiment, the inductance loop is formed from first and second wires which connect a first bonding pad on the integrated circuit chip to a first I/O pin of the package and a third and fourth wires which connect a second bonding pad on the chip to a second I/O pin of the package. To complete the inductor loop, the first and second I/O pins are connected by a third conductor between the pins. The third conductor may include one or more bonding wires and the I/O pins are preferably ones which are adjacent one another. However, the loop may be formed from non-adjacent connections of I/O pins based, for example, on loop-length requirements, space considerations, and/or other design or functional factors. In another embodiment, connection between the first and second I/O pins is established by making the I/O pins have a unitary construction.
