20140273291 | Wafer Strength by Control of Uniformity of Edge Bulk Micro Defects - A method is provided for qualifying a semiconductor wafer for subsequent processing, such as thermal processing. A plurality of locations are defined about a periphery of the semiconductor wafer, and one or more properties, such as oxygen concentration and a density of bulk micro defects present, are measured at each of the plurality of locations. A statistical profile associated with the periphery of the semiconductor wafer is determined based on the one or more properties measured at the plurality of locations. The semiconductor wafer is subsequently thermally treated when the statistical profile falls within a predetermined range. The semiconductor wafer is rejected from subsequent processing when the statistical profile deviates from the predetermined range. As such, wafers prone to distortion, warpage, and breakage are rejected from subsequent thermal processing. | 09-18-2014 |

20100258808 | THIN FILM TRANSISTOR AND MANUFACTURING METHOD THEREOF - A thin film transistor and a manufacturing method thereof are provided. A bottom gate, a gate insulating layer and an amorphous semiconductor layer are formed on a substrate. The amorphous semiconductor layer has an uneven upper surface. A laser annealing process is performed on the amorphous semiconductor layer through the uneven upper layer to transform the amorphous semiconductor layer into a polycrystalline semiconductor layer having a smaller-crystallizing-section and a greater-crystallizing-section. Another gate insulating layer, an upper gate and patterned photoresist layer are formed on the polycrystalline semiconductor layer. Patterns of the upper gate and the bottom gate are defined by the same photo-mask. A source/drain is formed in the polycrystalline semiconductor layer. An etching process with etching selectivity is performed on the upper gate and the patterned photoresist layer to make a length of the upper gate shorter than that of the bottom gate. | 10-14-2010 |

20150071323 | APPARATUS FOR IDENTIFYING MORPHOLOGY - An apparatus for identifying morphology comprises a substrate, a driving circuit, a readout circuit and an identifying circuit. The substrate comprises temperature sensors each comprising a sensing transistor. The driving circuit selects at least one of the transistors as a target sensing transistor, and outputs a driving signal to the target sensing transistor to heat the target sensing transistor in a heating period. The target sensing transistor senses a temperature change to generate a sensing signal in a sensing period after the heating period. The readout circuit reads the sensing signal, and the identifying circuit identifies the morphology according to the sensing signal. | 03-12-2015 |

20110020044 | PRINTING MEDIUM CLAMP MECHANISM OF BARCODE PRINTER - A printing medium clamp mechanism is provided for use in a barcode printer and includes a housing, at least one swivel arm, at least one resilient element, at least one medium roll clamps, and at least two movable arms. The housing comprises an inner casing arranged therein. The inner casing forms two through slots serving as tracks. The swivel arm is rotatably mounted to a bottom of the inner casing. The resilient element is connected between an end of the swivel arm and the inner casing to provide a biasing force for return rotation of the swivel arm. The medium roll clamps are respectively and movably received in the tracks. The two movable arms have first ends coupled to opposite ends of the swivel arm and opposite, second ends coupled to the medium roll clamps respectively, whereby the two medium roll clamps are coupled in a resilient manner to the swivel arms to be movable along the tracks of the inner casing for outward movement of separating from each other or inward movement of approaching each other and effecting clamping of a roll of printing medium. In this way, when the medium roll clamps are forced to outward move against the resilient biasing force, a roll of printing medium can be received and installed; and when the medium roll clamps are released, they are biased to return and clamp the roll of the printing medium. As such, a printing medium clamp mechanism featuring a resilient returning and clamping force for clamping a roll of printing medium is provided. | 01-27-2011 |
20110020045 | PRINTING MEDIUM ROLL CLAMPING SUPPORT OF BARCODE PRINTER - A printing medium roll clamping support is provided for use in a barcode printer and includes at least two bases, each having a top forming at least one connection section and at least two positioning sections, and at least two changeover devices, each having opposite surfaces respectively forming a first positioning ring and a second positioning ring. The bases are respectively and movably fit in tracks defined in a housing of the barcode printer to allow the bases to be selectively moved inward for clamping a roll of printing medium or moved outward for releasing the roll of printing medium. Each changeover device has a bottom forming a pivot joint section and at least two positioning elements. The pivot joint section corresponds to and is rotatably coupled to the connection section of the corresponding base so as to allow for selective rotation of the changeover device by 180 degrees to switch between the first positioning ring and the second positioning ring for clamping rolls of printing medium of different diameters. With the positioning elements fit into the positioning sections, the changeover device is securely retained on the top of the corresponding base. | 01-27-2011 |
