Abstract

PURPOSE:To improve the operational efficiency by exposing four field areas with a plurality of alignment marks formed in one area equal to one field at the center of the four fields. CONSTITUTION:Four fields areas a, b, c and d having square alignment marks 12 formed as illustrated, as basic unit, are arranged in large numbers on the wafer and the wafer is placed on the stage of the electron beam exposure equipment. After the alignment of the wafer by two marks formed at both side ends parallel to the facet of the wafer, the electron beam is positioned on the m area at the center of any zone in the four field areas. The electronic signal reflected from the square marks 12 with electronic beam is detected to find X and Y axes whereby alignment is performed by adjusting the errors. Thus, position detection can be done by one alignment in the four field areas thereby improving the operational efficiency of the exposure equipment.
