Abstract
The extent of a bow of a semiconductor device is suppressed in a case where the fillet width of an underfill resin is asymmetrical. The center positionof a chipis caused to deviate from the center positionof a wiring substratein a direction (the direction of the arrow B) reverse to the deviation direction (the direction of the arrow A) of the center positionof an underfill resinfrom the center positionof the chip. The center positionof a resin for encapsulationis caused to deviate from the center positionof the wiring substratein the same direction (the direction of the arrow A) as the deviation direction (the direction of the arrow A) of the center positionof the underfill resinfrom the center positionof the chip
