  • Patent number: 11259415
    Abstract: In conventional fluid discharge devices, a discharge head used should be increased in size according to increase in size of a workpiece such as silicon wafer. However, if the discharge head increases in length, a deformation amount of a mask used for discharging the fluid on the workpiece increases, thereby the discharging amount varies. Discharging the fluid in a reciprocating manner is performed using a fluid discharging device including a head unit having a width shorter than a length of the workpiece. A suction port having opening portions each having a slit shape are disposed on the both sides of the discharge nozzle in a vicinity of the discharge nozzle.

  • Patent number: 11234334
    Abstract: A printer deposits material onto a substrate as part of a manufacturing process for an electronic product; at least one transported component experiences error, which affects the deposition. This error is mitigated using transducers that equalize position of the component, e.g., to provide an “ideal” conveyance path, thereby permitting precise droplet placement notwithstanding the error. In one embodiment, an optical guide (e.g., using a laser) is used to define a desired path; sensors mounted to the component dynamically detect deviation from this path, with this deviation then being used to drive the transducers to immediately counteract the deviation. This error correction scheme can be applied to correct for more than type of transport error, for example, to correct for error in a substrate transport path, a printhead transport path and/or split-axis transport non-orthogonality.

  • Patent number: 11217358
    Abstract: Optically transparent, highly conductive conductor materials are provided, which in certain variations may also be flexible. Methods of making transparent conductive conductors, such as electrodes, are also provided. Such a method may include creating a groove pattern on a substrate that defines a two-dimensional array. Then an electrically conductive material may be selectively applied within the groove pattern of the substrate so as to create a transparent conductor (e.g., a transparent conductive electrode (TCE)). The transparent conductor has a sheet resistance of ?about 5 Ohms/Square and a transmissivity of ?about 50% for a predetermined range of target wavelengths of electromagnetic energy. Such methods may form linear micromesh conductive arrays and tortuous micromesh conductive arrays that can be used in a variety of optoelectronic applications, including as optically transparent, flexible and mechanically reconfigurable zeroth-order resonant (ZOR) antennas.
