A wafer having an SOI configuration and active regions having different surface orientations for different channel type transistors. In one example, semiconductor structures having a first surface orientation are formed on a donor wafer. Semiconductor structures having a second surface orientation are formed on a second wafer. Receptor openings are formed on the second wafer. The semiconductor structures having the first surface orientation are located in the receptor openings and transferred to the second wafer. The resultant wafer has semiconductor regions having a first surface orientation for a first channel type of transistor and semiconductor regions having a second surface orientation for a second channel type transistor.

One embodiment forms a gate dielectric layer over a substrate and then selectively deposits a first metal layer over portions of the gate dielectric layer in which a first device type will be formed. A second metal layer, different from the first metal layer, is formed over exposed portions of the gate dielectric layer in which a second device type will be formed. Each of the first and second device types will have different work functions because each will include a different metal in direct contact with the gate dielectric. In one embodiment, the selective deposition of the first metal layer is performed by ALD and with the use of an inhibitor layer which is selectively formed over the gate dielectric layer such that the first metal layer may be selectively deposited on only those portions of the gate dielectric layer which are not covered by the inhibitor layer.

In some embodiments, techniques include identifying a plurality of tasks associated with an identifier corresponding to an electronic device. A task series is generated so as to include the plurality of tasks, where each task in the series is associated with a performance time. When it is determined that the task has not been completed by the performance time, the task series is updated.

There is disclosed a system and method for applying an amorphous NiP alloy coating on pipes and rods, particularly for use in the oil and gas industries to inhibit corrosion, In an embodiment, the method comprises applying an amorphous nickel phosphorus or NiP alloy coating to pipes and rods for use in oil and gas industries, comprising; preparing a Watt's type nickel phosphorus (NiP) plating bath solution utilizing a Watt's type nickel electrolyte containing hypophosphorous acid; maintaining the plating bath solution temperature at between 120° F. and 170° F. adjusted to regulate phosphorus content over 11%; regulating a pH level of the plating bath solution between 1.0 and 3.0 utilizing sulphuric acid; and controlling the cathode current density in the range of 10-100 amps/sq/ft. Significant cost savings may be realized by using an electroplated nickel-phosphorus alloy over regular carbon steel alloy components at sufficient thickness to be pore free replacing the use of more expensive components made of stainless steels or nickel base alloys.

A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source. In an alternative embodiment, the radiation from the region of space may be transmitted to the sample via a beam homogeniser, for example an optical waveguide in the form of an optical fibre, which may be used to reduce or remove speckle where laser diodes are employed as the radiation sources. The device may be used to determine the particle size distribution of particles in a sample by a method employing Bayesian inference.

A security feature for an identification document and method for making it provide layers of security, including, for example, tamper evidence, optically variable effects, and personalized information that links the security information to the document and its bearer. The feature is made by printing a first material representing first information on a core layer of the document. This first material at least partially overlaps the core layer. One example is Xerographic printing of information about the ID document applicant and the applicant's photo. The process also applies a second material representing second information adjacent to the first material. One example is ink jet printing of personal information with a UV curable ink in the form of a relief pattern on the core layer. Finally, the process applies a laminate layer over the core layer. The laminate layer covers the first and second materials. The first and second materials adhere differently to the laminate and core layers such that removal of the laminate layer from the core layer causes a separation of the first and second materials. The relief pattern is made to give the document a tactile feel as well as create optically variable effects.
摘要:
A color laser engraving method engraves a document including a surface layer and one or more sub-layers. The sub-layer includes different colors and orientations of ink. A laser provides openings in the surface layer—to expose color ink in the sub-layer—to create color images and/or text. The different orientations of the colored inks include, e.g., circular, linear and overlapped groupings of ink. A sub-layer preferably includes many repeated instances of the grouping. A digital watermark is embedded in a document via transfer of the digital watermark in an embedded image or text, or by pre-embedding the document via altering intensity of colored inks on the original document card stock. A digital watermark can be carried via modulation with a pseudo-random noise sequence.
