摘要： In a first aspect, a lithography apparatus may comprise a mask designed using optical proximity correction (OPC), a pulsed laser source, and an active bandwidth control system configured to increase the bandwidth of a subsequent pulse in response to a measured pulse bandwidth that is below a predetermined bandwidth range and increase a bandwidth of a subsequent pulse in response to a measured pulse bandwidth that is above the predetermined bandwidth range. In another aspect an active bandwidth control system may include an optic for altering a wavefront of a laser beam in a laser cavity of the laser source to selectively adjust an output laser bandwidth in response to the control signal. In yet another aspect, the bandwidth of a laser having a wavelength variation across an aperture may be actively controlled by an aperture blocking element that is moveable to adjust a size of the aperture.
摘要翻译：在第一方面，光刻设备可以包括使用光学邻近校正（OPC），脉冲激光源和有源带宽控制系统设计的掩模，该有源带宽控制系统被配置为响应于测量的脉冲带宽来增加后续脉冲的带宽，低于预定带宽范围，并且响应于高于预定带宽范围的测量脉冲带宽增加随后脉冲的带宽。在另一方面，有源带宽控制系统可以包括用于改变激光源的激光腔中的激光束的波前的光学器件，用于响应于控制信号选择性地调节输出激光器带宽。在另一方面，具有穿过孔的波长变化的激光器的带宽可以由可移动以调节孔径的孔径阻挡元件主动地控制。
