Abstract
A method of manufacturing a semiconductor device includes forming a first metal pad in each of a plurality of first regions on a first substrate so that warpage is generated on the first substrate. The method further includes forming a second metal pad in each of a plurality of second regions on a second substrate via a predetermined pattern. The method further includes bonding, after forming the first metal pad and the second metal pad, the first substrate with the second substrate. Moreover, the method further includes: making a correction, at a time of forming the predetermined pattern in each of the plurality of second regions on the second substrate, to change a position of the predetermined pattern in each of the plurality of second regions in a direction of being closer to a center of the second substrate for a first direction and to change the position of the predetermined pattern in a direction of being farther from the center of the second substrate for a second direction.
