Claim 9:
10. A method for manufacturing a semiconductor device, comprising steps of:
providing a semiconductor substrate;
forming a plurality of chip regions and strip lines for separating the chip regions on the semiconductor substrate, wherein a plurality of active regions formed synchronously with the chip regions being provided in the strip lines, a plurality of active regions staggered and arranged in parallel, wherein an extending direction of the plurality of active regions has an included angle in the range of 60°-80° with a row direction;
and
forming a plurality of connecting structures located at ends of the active regions, by which a plurality of active regions on a same column are sequentially connected end to end, one of the plurality of active regions and corresponding connecting structures disposed at a head end and a tail end of the one of the plurality of active regions jointly constitute a “Z”-shaped test key in a column direction.
