Shape Or Contour Of Light Control Surface Altered Patents (Class 359/291)
  • Patent number: 10310355
    Abstract: A spatial light modulator having an active and a peripheral region, wherein coherent light impinges on both regions, but due to a higher spatial frequency of pixels within the peripheral region, and due to biasing the peripheral region pixels to maximize dispersion of reflected light therefrom, a majority of light reflected from the peripheral region is directed outside of a three-dimensional target window. A spatial frequency of the pixels in the active region is selected such that maximum dispersion of reflected light from the active region is incident within the three-dimensional target window. In this way, incident light that does not reflect from the active region need not be absorbed, or blocked, but instead can be reflected, but still fails to interfere with the target window.

  • Patent number: 9703208
    Abstract: MQW devices, IC chips and methods may be used in semiconductor lithography patterning systems. An MQW device includes an array of pixels that have transmission elements and associated support circuits. The support circuits have preliminary memory cells and final memory cells. The final memory cells store transmittance values that control transmittances of the associated transmission elements. This way, exposure of a target with a lithography system for purposes of patterning the target may be performed through the transmission elements according to the controlled transmittances, while subsequent transmittance values are being received by the preliminary memory cells from memory banks. The exposure of the target therefore needs to pause for less time, in order to wait for the MQW device to be refreshed with the subsequent transmittance values. Accordingly the whole semiconductor lithography patterning system may operate faster and thus have more throughput.

  • Patent number: 9541576
    Abstract: A system and method for electrochemical force microscopy are provided. The system and method are based on a multidimensional detection scheme that is sensitive to forces experienced by a biased electrode in a solution. The multidimensional approach allows separation of fast processes, such as double layer charging, and charge relaxation, and slow processes, such as diffusion and faradaic reactions, as well as capturing the bias dependence of the response. The time-resolved and bias measurements can also allow probing both linear (small bias range) and non-linear (large bias range) electrochemical regimes and potentially the de-convolution of charge dynamics and diffusion processes from steric effects and electrochemical reactivity.
