  • Patent number: 8118982
    Abstract: A method and apparatus for physical vapor deposition of films on a substrate is provided. The apparatus comprises a series of connected sputtering chambers through which a substrate passes to undergo sequential deposition processes. The chambers have passages through which the substrates move, and through which process gases may leak. Target gas flows to each chamber are established by operating each chamber while adjacent chambers are idle, measuring the extent of gas communication between the chambers, and reducing the flows by an amount based on the extent of gas leakage.

  • Patent number: 8119525
    Abstract: Methods of controlling deposition of metal on field regions of a substrate in an electroplating process are provided. In one aspect, a dielectric layer is deposited under plasma on the field region of a patterned substrate, leaving a conductive surface exposed in the openings. Electroplating on the field region is reduced or eliminated, resulting in void-free features and minimal excess plating. In another aspect, a resistive layer, which may be a metal, is used in place of the dielectric. In a further aspect, the surface of the conductive field region is modified to change its chemical potential relative to the sidewalls and bottoms of the openings.

  • Patent number: 8115506
    Abstract: Methods and apparatus for determining whether a malfunctioning pixel in a large area substrate, such as a liquid crystal display (LCD) panel, is due to the pixel itself or to the driver circuit for that pixel and for localizing any driver circuit defects are provided. In an effort to localize the driver circuit defects, test pads coupled to the input and/or output of certain driver circuits may be fabricated on the substrate. The voltage or charge of these test pads may be detected using any suitable sensing device, such as an electron beam, an electro-optical sensor, or an electrode in close proximity to the surface of the pixels and/or drivers capacitively coupled to the pixel or driver. For some embodiments, the defective driver circuits may be repaired in the same area as the test area or may be transported via conveyor or robot to a separate repair station.

  • Patent number: 8111727
    Abstract: Semiconductor laser diodes, particularly broad area single emitter (BASE) laser diodes of high light output power, are commonly used in opto-electronics. Light output power and stability of such laser diodes are of crucial interest and any degradation during normal use is a significant disadvantage. The present invention concerns an improved design of such laser diodes, the improvement in particular significantly minimizing or avoiding degradation of such laser diodes at very high light output powers by controlling the current flow in the laser diode in a defined way. The minimization or avoidance of (front) end section degradation of such laser diodes significantly increases long-term stability compared to prior art designs. This is achieved by controlling the carrier injection into the laser diode in the vicinity of its facets in such a way that abrupt injection current peaks are avoided.
