    摘要: A light patterning system comprises an illumination system that supplies a beam of radiation having a certain wavelength (λ). An array of reflective pixels patterns the beam, wherein the array includes pixels having at least a first tilting mirror that is logically coupled to a second tilting mirror. In an embodiment, the first and second tilting mirrors are (i) substantially adjacent to each other; and (ii) offset in height from each other by a first mirror displacement. A projection system is included that projects the patterned beam onto a target. In alternate embodiment, the array of reflective pixels includes pixels having first through fourth tilting mirrors that are logically coupled to each other. The first through fourth tilting mirrors are (i) respectively offset in height from a reference plane by first through fourth mirror displacements, and (ii) are respectively arranged clockwise in a substantially square pattern.

    摘要: A method and system are used to modify pattern data obtained in relation to a pattern on a static patterning device. It is suggested that, in an example when a maskless lithography tool is used, continuous OPC-enhanced features used for maskless lithography rasterization should include a variation in local amplitude and phase transmittance that matches modulation capabilities of a patterning device being used. The modified pattern data is used by a dynamic patterning device to pattern impinging light, which is then projected onto an object. The system and method comprise using a pattern data generating device, a modification device, a dynamic pattern generator, and a projection system. The pattern data generating device generates pattern data corresponding to a pattern on a static patterning device. The modification device receives the pattern data and modifies the pattern data using characteristics of a type of the dynamic pattern generator being used. The dynamic pattern generator receives the modified patterned data and uses the modified pattern data to pattern the beam of radiation. The projection system projects the patterned beam onto the object.

    摘要: A system and method to manufacturing a device provide a substrate and perform at least one exposure step. Each exposure step projects a patterned beam of radiation, which was patterned using an individually controllable elements, onto a target portion of the substrate. The projected patterned beam includes a plurality of pixels. Each exposure step also: (a) ordinarily controls the elements, such that each pixel delivers a radiation dose no greater than a predetermined normal maximum dose to the target portion in the exposure step; and (b) exceptionally controls the elements, such that at least one selected pixel delivers an increased radiation dose, greater than the normal maximum dose. The increased dose may be delivered to compensate for the effect of a defective element at a known position in the array on a pixel adjacent a selected pixel. Alternatively, it may compensate for underexposure of the target portion at the location of a selected pixel resulting from exposure of that location to a pixel affected by a known defective element in another exposure step. The invention uses doses up to the predetermined normal maximum for normal printing, but reserves at least one increased dose for compensation purposes. Accordingly, even when a dead black pixel falls in the middle of a group of surrounding white pixels it can be compensated for by increasing the radiation dose delivered by one or more of those neighboring white pixels, above the normal fully white value.
