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.
Abstract translation: MQW器件，IC芯片和方法可用于半导体光刻图形系统。 MQW器件包括具有传输元件和相关支持电路的像素阵列。 支持电路具有初始存储单元和最终存储单元。 最后的存储单元存储控制相关传输元件的透射率的透射率值。 这样，可以通过根据受控透射率的传输元件来执行用于图案化目标的光刻系统的目标物的曝光，而由存储体组中的预备存储器单元接收随后的透射率值。 因此，目标的曝光需要暂停较少的时间，以等待随后的透射率值来刷新MQW器件。 因此，整个半导体光刻图案化系统可以更快地操作并且因此具有更多的吞吐量。
