    Abstract: An integrated circuit is provided including a narrow gate stack having a width less than or equal to 65 nm, including a silicide region comprising Pt segregated in a region of the silicide away from the top surface of the silicide and towards an lower portion defined by a pulldown height of spacers on the sidewalls of the gate conductor. In a preferred embodiment, the spacers are pulled down prior to formation of the silicide. The silicide is first formed by a formation anneal, at a temperature in the range 250° C. to 450° C. Subsequently, a segregation anneal at a temperature in the range 450° C. to 550° C. The distribution of the Pt along the vertical length of the silicide layer has a peak Pt concentration within the segregated region, and the segregated Pt region has a width at half the peak Pt concentration that is less than 50% of the distance between the top surface of the silicide layer and the pulldown spacer height.

  • Patent number: 8008181
    Abstract: Misfit dislocations are redirected from the buffer/Si interface and propagated to the Si substrate due to the formation of bubbles in the substrate. The buffer layer growth process is generally a thermal process that also accomplishes annealing of the Si substrate so that bubbles of the implanted ion species are formed in the Si at an appropriate distance from the buffer/Si interface so that the bubbles will not migrate to the Si surface during annealing, but are close enough to the interface so that a strain field around the bubbles will be sensed by dislocations at the buffer/Si interface and dislocations are attracted by the strain field caused by the bubbles and move into the Si substrate instead of into the buffer epi-layer. Fabrication of improved integrated devices based on GaN and Si, such as continuous wave (CW) lasers and light emitting diodes, at reduced cost is thereby enabled.

  • Publication number: 20110175103
    Abstract: A semiconductor device has a satisfactory ohmic contact on a p-type principal surface tilting from a c-plane. The principal surface 13a of a p-type semiconductor region 13 extends along a plane tilting from a c-axis (axis <0001>) of hexagonal group-III nitride. A metal layer 15 is deposited on the principal surface 13a of the p-type semiconductor region 13. The metal layer 15 and the p-type semiconductor region 13 are separated by an interface 17 such that the metal layer functions as a non-alloy electrode. Since the hexagonal group-III nitride contains gallium as a group-III element, the principal surface 13a comprising the hexagonal group-III nitride is more susceptible to oxidation compared to the c-plane of the hexagonal group-III nitride. The interface 17 avoids an increase in amount of oxide after the formation of the metal layer 15 for the electrode.

Strain is defined as follows: a given layer has a bulk lattice constant abulk corresponding to a lattice constant of a free standing material of a same composition as that layer and an in-plane lattice constant ain-plane corresponding to a lattice constant of that layer as grown in the structure. The amount of strain in a layer is |(ain-plane?abulk)|/abulk. In some embodiments, the strain in the light emitting layer is less than 1%.

The group-III nitride-based light emitting diode includes a substrate, an n-type nitride-based cladding layer formed on the substrate, a nitride-based active layer formed on the n-type nitride-based cladding layer, a p-type nitride-based cladding layer formed on the nitride-based active layer, and a p-type multi-layered ohmic contact layer formed on the p-type nitride-based cladding layer and including thermally decomposed nitride. The thermally decomposed nitride is obtained by combining nitrogen (N) with at least one metal component selected from the group consisting of nickel (Ni), copper (Cu), zinc (Zn), indium (In) and tin (Sn). An ohmic contact characteristic is enhanced at the interfacial surface of the p-type nitride-based cladding layer of the group-III nitride-based light emitting device, thereby improving the current-voltage characteristics.

  • Publication number: 20110061731
    Abstract: Fabrication of a solar cell using a printed contact mask. The contact mask may include dots formed by inkjet printing. The dots may be formed in openings between dielectric layers (e.g., polyimide). Intersections of overlapping dots may form gaps that define contact regions. The spacing of the gaps may be dictated by the alignment of nozzles that dispense the dots. Using the dots as a contact mask, an underlying dielectric layer may be etched to form the contact regions through the underlying dielectric layer. Metal contact fingers may be formed over the wafer to form electrical connections to corresponding diffusion regions through the contact regions.

  • Publication number: 20110049540
    Abstract: One embodiment of the present invention provides a method for fabricating light-emitting diodes (LEDs). The method includes fabricating an InGaAlN-based multilayer LED structure on a conductive substrate. The method further includes etching grooves of a predetermined pattern through the active region of the multilayer LED structure. The grooves separate a light-emitting region from non-light-emitting regions. In addition, the method includes depositing electrode material on the light-emitting and non-light-emitting regions, thereby creating an electrode. Furthermore, the method includes depositing a passivation layer covering the light-emitting and non-light-emitting regions. Moreover, the method includes removing the passivation layer on the electrode to allow the non-light-emitting regions which are covered with the electrode material and the passivation layer to be higher than the light-emitting region and the electrode, thereby protecting the light-emitting region from contact with test equipment.
