    摘要: A method for forming different active thicknesses on the same silicon layer includes masking the silicon layer and exposing selected regions of the silicon layer. The thickness of the silicon layer at the exposed regions is changed, either by adding silicon or subtracting silicon from the layer at the exposed regions. Once the mask is removed, the silicon layer has regions of different active thicknesses, respectively suitable for use in different types of devices, such as diodes and transistors.

    摘要: A method that includes forming a gate of a semiconductor device on a substrate and forming a recess for an embedded silicon-straining material in source and drain regions for the gate. In this method, a proximity value, which is defined as a distance between the gate and a closest edge of the recess, is controlled by controlling formation of an oxide layer provided beneath the gate. The method can also include feedforward control of process steps in the formation of the recess based upon values measured during the formation of the recess. The method can also apply feedback control to adjust a subsequent recess formation process performed on a subsequent semiconductor device based on the comparison between a measured proximity value and a target proximity value to decrease a difference between a proximity value of the subsequent semiconductor device and the target proximity value.

    摘要: An opaque matrix that defines transparent apertures may be formed on a lenticular lens by applying an infrared radiation sensitive material to the flat surface of the lenticular lens, projecting infrared radiation through the lenticular lens onto the infrared radiation sensitive material to create exposed and unexposed areas of the infrared radiation sensitive material, and removing the exposed areas of the infrared radiation sensitive material from the flat surface of the lenticular lens. The infrared radiation sensitive material includes an infrared absorbing dye and a colorant. The infrared radiation sensitive material may also include a binder. A barrier layer may be disposed between the flat surface of the lenticular lens and the infrared radiation sensitive material. The barrier layer may include a binder, an infrared absorbing dye, and a crosslinking agent. The resulting lenticular lens may be used in a rear projection television screen or monitor.

    摘要: A method and system to locate and detect voids in films that are involved in critical dimension (CD) structures and non-critical dimension structures in semiconductor devices are presented. One or more test structures (resolution devices) are formed on a semiconductor wafer. A scanning electron microscope is operated in voltage contrast mode to obtain a digital representation of the test structure. The voltage contrast image of the test structure is then analyzed with a system which automates the location, identification, and categorization of voids in the test structure. Additionally, the method is more sensitive to electrical marginalities caused by voids than other wafer electrical testing methods. The method is suitable inline monitoring during a manufacturing process by utilizing the automation of void identification, location, and categorization as a process monitoring parameter.

    摘要: Various embodiments of a test circuit and methods of fabricating and using the same are provided. In one aspect, a test circuit includes a semiconductor substrate and a mask thereon that has an opening to enable impurity doping of selected portions of the test circuit. A plurality of circuit devices are provided on the substrate that have respective active regions positioned at staggered known distances from the mask opening. Each of the plurality of circuit devices has a gate electrode that extends to the opening and has a first impurity region of a first conductivity type and a second impurity region of a second and opposite conductivity type. Where the predicted on-state output current of a given circuit device exceeds an actual output current of the given circuit device, there is indication of an overlap between the first and second impurity regions of the gate electrode of the given device.

    摘要: The present invention relates to an electrochemical process for synthesizing carboxylic acids by reduction of gaseous oxides of carbon in which a gas transfer electrode is used as the cathode.The gas transfer electrodes are preferably used as hydrophobic gas transfer electrodes. In carrying out the process it is particularly preferred to use porous, hydrophobic gas transfer electrodes made from an electrocatalyst e.g. carbon, bound in a polymer such as polyethylene or polytetrafluoroethylene (PTFE). In the case of some reactions another electro-catalyst may be added to the carbon/polymer mixture.The process is particularly suited to producing acids such as formic acid and oxalic acid.
