A semiconductor device and method of making the same wherein the semiconductor device includes a pFET region including a SiGe channel having a Si-rich top surface within the gate portion, and an nFET region including a Si channel. The method includes subjecting both the pFET and nFET regions to a single high-temperature anneal process thereby avoiding the need for an additional spike anneal process at RMG module.

Described in detail herein are methods and systems to dynamically process machine-readable elements based on an alternate set of instructions associated with an appended portion of an identifier encoded in the machine-readable element.

Provided is an optical information reading device that can reduce an installation load on a user, and can accurately read a code provided to each of various workpieces. A polarized illumination light source includes light emitters that irradiate the workpiece with illumination light through a polarization filter. A non-polarized illumination light source includes light emitters that irradiate the workpiece with illumination light without through a polarization filter. An imaging element is provided with a polarization filter having a polarization direction different from a polarization direction of the polarization filter of the light emitters. Either of the polarized illumination light source and the non-polarized illumination light source is used in accordance with the workpiece.

A machine readable symbol reader can provide illumination form portions other than or in addition to the head of the reader, to enhance the ability to successfully read machine-readable symbols, for example symbols on curved surfaces and/or DPM symbols. A machine readable symbol reader include a first set of receiving optics in a head of the reader and a second set of receiving optics in a portion of the reader other than the head, to provide an alternative line of sight or field of view.

An optical information detecting apparatus is formed as an integrated, solid state monolithic structure. The monolithic structure includes a plurality of light sensors disposed on a substrate and electrically isolated from one another, a plurality of light emitting elements disposed on the substrate and electrically isolated from one another, the light sensors being optically isolated from the light emitting elements, and a circuit connected to the light emitting elements to generate light towards a target and connected to the light sensors to detect reflected light from the target, wherein a signal is generated in response to the detected light. The signal is indicative of an optical characteristic of the target.

Systems and methods for cancelling noise caused by the flicker of ambient lights are provided. Such noise cancelling systems and methods may be incorporated in a laser-based barcode scanning device. In one example, a barcode scanning device includes a light source, a first sensor, a second sensor, and a noise cancelling circuit. The light source is configured to emit a beam of light. The first sensor is configured to detect a first optical signal indicative of light reflecting off of a barcode. The reflected light may originate from the light source and from at least one ambient light source in the vicinity of the barcode scanning device. The second sensor is configured to detect a second optical signal indicative of light originating from the at least one ambient light source. The noise cancelling circuit is configured to obtain a noise-cancelled scanning signal from the first and second optical signals.
