发明名称 RETICLE AND PRODUCTION OF SEMICONDUCTOR DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To improve the accuracy in the measurement of superposition accuracy. SOLUTION: This reticle is provided with a chip region which is within a projection range of an exposure device and is formed with semiconductor circuit patterns and a plurality of marks for measurement for measuring the superposition accuracy in a scribe line region which is the region exclusive of the chip region. The marks for measurement are composed of plural main patterns 114 which are arranged apart a prescribed pitch 111 along the measurement direction (121) of the superposition accuracy and auxiliary patterns 113 and 115 which are made equal in the pitch 112 with the first pattern described above to the prescribed pitch 111 described above. The resist patterns corresponding only to the plural main patterns are formed and the formed resist patterns are subjected to the measurement of the superposition accuracy by the constitution described above.</p>
