    摘要: A maskless lithography system that writes patterns on an object. The system can include an illumination system, the object, spatial light modulators (SLMs), and a controller. The SLMs can pattern light from the illumination system before the object receives the light. The SLMs can include a leading set and a trailing set of the SLMs. The SLMs in the leading and trailing sets change based on a scanning direction of the object. The controller can transmit control signals to the SLMs based on at least one of light pulse period information, physical layout information about the SLMs, and scanning speed of the object. The system can also correct for dose non-uniformity using various methods.

    摘要: An array of individually controllable elements is comprised of elements, each formed of a stack of layers of dielectric material. At least one layer is an electro-optical material. The at least one layer's refractive index for radiation that is plane polarized in a given direction can be changed by application of a voltage in order to change the reflection/transmission characteristic of the boundary between this layer and the adjacent layer.

    摘要: A system and method are used for pulse to pulse dose control in an illumination system, used, for example, in a lithography or a maskless lithography machine. The system and method can be used to decrease effective laser pulse-to-pulse variability in lithographic lasers, allowing adequate dose control using a minimum number of pulses (e.g. as little as one pulse).
