Method for manufacturing semiconductor device

Abstract

In a method for manufacturing a semiconductor device, a first structure is formed on a first substrate. A first bonded body is formed by bonding a supporting substrate to a first principal surface, on which the first structure is formed, of the first substrate. The supporting substrate is higher in rigidity than the first substrate. The first substrate is removed from the first bonded body. A second structure is formed on a second substrate. A third structure is formed on a third substrate. A second bonded body is formed by bonding a second principal surface, on which the second structure is formed, of the second substrate to a third principal surface, on which the third structure is formed, of the third substrate. The third substrate is removed from the second bonded body. A third bonded body is formed by bonding a fourth principal surface, which is exposed after the first substrate is removed, of the first bonded body to a fifth principal surface, which is exposed after the third substrate is removed, of the second bonded body. The supporting substrate is removed from the third bonded body.
