    • A method of forming by projection an integrated circuit pattern on a first semiconductor wafer, wherein a plurality of reference marks are projected onto a second semiconductor wafer by the irradiation of radiant rays from a projector apparatus used to form the integrated circuit pattern onto the first semiconductor wafer. The positions of the reference marks projected onto the second semiconductor wafer are measured, thereby measuring the projection distortion peculiar to the projector apparatus. As the next step, a projection mask used to form the integrated circuit pattern is produced with the use of the measured projection distortions which has a distortion opposite that of the projector so as to offset its projection distortion. The mark is mounted in the projector apparatus, and the radiant rays are irradiated onto the mask thus projecting the integrated circuit pattern onto the first semiconductor wafer.
    • 一种通过将集成电路图案投影在第一半导体晶片上而形成的方法,其中多个参考标记通过从用于形成集成电路图案的投影仪设备的辐射线照射到第一半导体晶片上而投影到第二半导体晶片上 晶圆。 测量投射到第二半导体晶片上的参考标记的位置,从而测量投影仪设备特有的投影失真。 作为下一步骤,通过使用具有与投影仪相反的失真的测量的投影失真来产生用于形成集成电路图案的投影掩模,以抵消其投影失真。 标记安装在投影仪设备中,并且将辐射线照射到掩模上,从而将集成电路图案投影到第一半导体晶片上。
