    摘要: An x-ray irradiation apparatus and x-ray exposure apparatus provide improved x-ray generation. The x-ray irradiation apparatus includes a target material feed-out device to provide a target material in a feed-out direction to a specified target position and a laser to provide laser light to the specified target position to cause the target material to emit x-rays. In some configurations, an x-ray generation position control device may be used to determine and control a position of x-ray generation, a rotary mechanism may be operatively connected to the target material feed-out device to axially rotate the target material feed-out device about the feed-out direction, and/or a target feed-out control device may be used to detect and control the position of the target material feed-out device.

    摘要: A gas curtain device is employed to deflect debris that is generated by an extreme ultraviolet and soft x-ray radiation discharge source such as an electric discharge plasma source. The gas curtain device projects a stream of gas over the path of the radiation to deflect debris particles into a direction that is different from that of the path of the radiation. The gas curtain can be employed to prevent debris accumulation on the optics used in photolithography.

    摘要: A solid target (11) is formed with a cavity (12). The inner wall of the solid target at the cavity is ablated by ablation pulsed laser beams (13). The solid target is left standing until a highly densified portion (15) of a vaporized substance (14) is formed in the space within the cavity (14), and the highly densified portion (15) is then irradiated with heating pulsed laser beams (17), thereby forming high-temperature plasma (18) for generating radiation rays (19). As a result, good-quality radiation rays accompanied by a minimal amount of debris can be generated.
