Patent ID: 8889483

Claim:
A method comprising: preparing a first substrate including a first surface and one or more bump groups, each bump group on the first substrate formed of a different array of bumps arrayed with a respective pitch, each bump group having a number of bumps along a same first direction being larger than a number of bumps along a same second direction perpendicular to the first direction, a distance by which the bump groups are spaced apart from each other is larger than the pitch between the bumps forming the bump groups, the one or more bump groups comprising a first bump group formed on the first surface, the first bump group comprises a plurality of first bumps arranged in an array with a certain pitch, a sum of the first bumps in a first line along the first direction is larger than that of the first bumps in a second line along the second direction and differing from the first line; and supplying an insulating resin to the first substrate so that the insulating resin flows from an edge of the first substrate along the second line, wherein the one or more bump groups includes a third bump group, the third bump group comprises a plurality of third bumps arranged in an array with another certain pitch that is larger than the certain pitch, the sum of the third bumps in a fifth line is smaller than that of the third bumps in a sixth line, the fifth line being substantially parallel to the first line, the sixth line being substantially parallel to the second line, and a distance between the first bump group and the third bump group is larger than the certain pitch.
