Abstract:
1. A method comprising: arranging a first bonding layer of a predetermined thickness on at least a first functional region and a second functional region provided on a release layer including a first and a second release layers, which include respective materials whose decompositions or decreases in bonding strength occur when subjected to different processes, on a first substrate, and a region, to which the first functional region is to be transferred, on a second substrate; bonding the first functional region to the second substrate through the first bonding layer; subjecting the first release layer to a first process to separate the first substrate from the first functional region at the first release layer; arranging a second bonding layer of a predetermined thickness on at least one of the second functional region on the first substrate, and a region, to which the second functional region is to be transferred, on the second substrate or a region, to which the second functional region is to be transferred, on a third substrate; bonding the second functional region to the second or the third substrate through the second bonding layer; and subjecting the second release layer to a second process to separate the first substrate from the second functional region at the second release layer.
