Abstract

A method for manufacturing a semiconductor device is provided. The method includes forming a plurality of light-emitting elements on a first substrate and forming a first pattern array on a second substrate. The method also includes transferring the plurality of light-emitting elements from the first substrate to the second substrate. The method further includes forming the first pattern array on a third substrate. In addition, the method includes transferring the plurality of light-emitting elements from the second substrate to the third substrate. The method also includes forming a second pattern array on a fourth substrate. The method further includes transferring the plurality of light-emitting elements from the third substrate to the fourth substrate. The pitch between the plurality of light-emitting elements on the first substrate is different than the pitch of the first pattern array.
