摘要:
An image processing method for boundary resolution enhancement is disclosed. Firstly, an image is transferred into an image layer. Noise of the image layer is removed by a bilateral filter and crisp edges are retained at the same time. Moreover, the image layer is interpolated by an interpolation filter for resolution enhancement. The image processing method of the present invention can lower the image blur degree substantially, enhance the image resolution and be widely implemented in all sorts of image/video processing hardware devices.

A light emitting device with magnetic field includes a light-emitting structure and a first magnetic-source layer. The light-emitting structure includes a first doped structural layer, a second doped structural layer, an active layer between the two doped structural layers, a first electrode, and a second electrode. The first magnetic-source layer is integrated with the light-emitting structure to produce a magnetic field in the light-emitting structure. The magnetic field transversely shifts a driving current of the light-emitting structure to redistribute in the light-emitting structure.

The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.

Removing photoresist from alignment marks on a semiconductor wafer using a wafer edge exposure process is disclosed. The alignment marks on the wafer are covered by photoresist used in conjunction with semiconductor processing of one or more layers deposited on the semiconductor wafer. One or more parts of the edge of the wafer are exposed to remove the photoresist from these parts and thus reveal alignment marks on the wafer. The exposure of the one or more parts of the wafer is accomplished without performing a photolithographic clear out process. Rather, a wafer edge exposure (WEE) process is inventively utilized. Once the WEE process is performed, subsequent layers may be deposited by aligning them using the revealed alignment marks.
摘要:
A partial reflective laser output device comprising a partial reflective unit mounted on a laser output device (such as a vertical cavity emitting laser), the partial reflective unit allowing the laser beam emitted from the laser output device to be partially reflected while the rest penetrating through. On one hand, this device decreases the intensity of output laser light so as to comply with the eye safety standard; the reflected light is absorbed by a photodiode (PD) to perform auto power control on the laser output device on the other. In addition, by adjusting the tilting angle of the partial reflective unit or making a curvature thereon, the reflected light can have no destructive interference with the output light and can even be focused onto the PD so that there would be no relative intensity noise problem and the size of the PD can be made smaller to lower the cost.
摘要:
A new method of metallization using a tungsten plug is described. Semiconductor device structures are provided in and on a semiconductor substrate. An insulating layer covers the semiconductor device structures wherein a contact opening is made through the insulating layer to the semiconductor substrate. A barrier layer is deposited conformally over the surface of the insulating layer and within the contact opening. A stress buffer layer is deposited overlying the barrier layer wherein the stress buffer layer prevents volcano defects. A tungsten plug is formed within the contact opening to complete the formation of the tungsten plug metallization without volcano defects in the fabrication of an integrated circuit device.
摘要:
Plasma reactors are used extensively in the manufacture of integrated circuits for the deposition and etching of thin films at low temperatures. Their range of operating temperatures and gas pressures make them highly susceptible to build-up of deposits on the inner surfaces of the reaction chamber which subsequently become dislodged by vibrations, stresses, and other aggravations and are dispersed within the system as particulates. The monitoring of particulate accumulation on wafers is conventionally done by subjecting a test wafer to a simulated operation within the tool under gas flow alone. Some types of plasma reactors incorporate oscillating gas dispersion housings in order to improve homogeneity of the gas mixture. The motion of these housings can induce significant particle displacement within the chamber. The correct monitoring procedure for these tools must therefore include the motion of the distribution housing in addition to the conventional procedures.
摘要:
A process for preventing the formation of precipitates on a substrate surface containing titanium after a contact layer (e.g., tungsten layer) etch back. The process involves removing the precursor chemicals of the precipitate. With the invention, the precursor are removed by baking the substrate at a temperature of approximately 120.degree. C. for approximately 80 seconds. Preferably, the baking process is performed in situ by a halogen lamp mounted on the exit loading dock of the etcher thereby not impacting the wafer throughput of the etcher.
