Abstract:
1. A method for connecting substrates, comprising: preparing a first wiring substrate having a first substrate including a first surface, the first surface having a first region and a second region which are provided with a first metal wire, wherein an area ratio between the first region and the first metal wire in the first region is different from an area ratio between the second region and the first metal wire in the second region; electrically bonding a second metal wire on a second substrate to the first metal wire provided in the first region of the first wiring substrate; heating the first wiring substrate to bend the first wiring substrate between the first region and the second region; and electrically connecting a third wiring located in a first surface of a third substrate to the first metal wire provided in the second region of the first wiring substrate, thereby mounting the first wiring substrate on the third substrate in a manner that a portion or the entirety of the first surface of the first substrate is nonparallel to the first surface of the third substrate.
