  • Patent number: 10488762
    Abstract: Embodiments of the present disclosure provide improved photolithography systems and methods using a solid state emitter array. The solid state emitter array comprises solid state emitter devices arranged in rows and columns, wherein each solid state emitter device comprises two or more subpixels. Each solid state emitter device comprises one program gate which may transmit a voltage to a state storage node. The state storage node is in electrical communication with a drive gate. The drive gate is in communication with two or more solid state emitter subpixels. The arrangement of a plurality of subpixels in communication with a single drive gate allows more than one pulse to be delivered to the drive gate, resulting in illumination of more than one subpixel at each drive gate. The redundancy results in improved data efficiency.

  • Patent number: 10474041
    Abstract: The present disclosure generally relates to lithography devices comprising an autofocus system. The autofocus system is configured to individually focus and adjust a plurality of digital micromirror devices. The autofocus system comprises a single light beam and a diffractive optical element configured to split the single light beam into two or more split beams. The two or more split beams are directed to a beam splitter. The two or more split beams are then reflected off the surface of a substrate to at least one position sensor. The position sensor is configured to measure the position of each of the two or more split beams. At least one digital micromirror device is then individually adjusted based on the measured position to adjust the focus of the at least one digital micromirror device with respect to surface height and tilt variations of the substrate.

  • Publication number: 20190332020
    Abstract: Systems and methods discussed herein relate to patterning substrates during lithography and microlithography to form features to a set or sets of critical dimensions using dose. The dose maps are generated based upon images captured during manufacturing to account for process variation in a plurality of operations employed to pattern the substrates. The dose maps are used along with imaging programs to tune the voltages applied to various regions of a substrate in order to produce features to a set or sets of critical dimensions and compensate for upstream or downstream operations that may otherwise result in incorrect critical dimension formation.

  • Publication number: 20190332017
    Abstract: Embodiments of the present disclosure provide improved photolithography systems and methods using a solid state emitter device. The solid state emitter device includes an array of solid state emitters arranged in a plurality of horizontal rows and vertical columns. The variable intensity of each group of solid state emitters, for example an entire row or column of solid state emitters, is controllable for improved field brightness uniformity and stitching. Controlling the variable intensity includes, for example, varying the signal, such as voltage, that is applied to each of the rows of solid state emitters to attenuate the brightness from the middle of the array to the edges of the array to accommodate for overlapping exposures during photolithography processing.

  • Patent number: 10012910
    Abstract: Multi-beam pattern generators employing processors to vary delivered dose of writing beams according to photoresist thicknesses, and associated methods are disclosed. A pattern generator may write a pattern upon a substrate having a photoresist which is sensitive to the writing beams. The pattern may be written in respective writing cycles when the writing beams write at least a portion of the pattern at writing pixel locations. A beam actuator of the pattern generator may independently direct the writing beams to the writing pixels to deliver respective pixel doses during each writing cycle. Pixel doses delivered may be adjusted according to a thickness of the photoresist at various writing pixel locations according to one or more approaches, using one or more of: actuator dwell times, emitted pulse duration, emitted pulse frequency, and emitted pulse intensity. In this manner, additional dimensional control is provided for substrates having variable photoresist thicknesses.
