Abstract
A laminate is provided comprising a support, a resin layer, a metal layer, an insulating layer, and a redistribution layer. The resin layer comprises a photo-decomposable resin having light-shielding properties and has a transmittance of up to 20% with respect to light of wavelength 355 nm. The laminate is easy to fabricate and has thermal process resistance, the support is easily separated, and a semiconductor package is efficiently produced.
