Substrate assembly and assembly package

Abstract

A substrate assembly is disclosed, comprising a carrier board defining a planar direction and a plurality of substrates adjacently arranged thereon. Each substrate has opposite first and second surfaces, with a temporary adhesive layer bonding the second surface to the carrier board. A functional material fills the gaps between adjacent substrates. The carrier board's area is no less than the total area of the substrates. Crucially, in a direction perpendicular to the planar direction, the height difference between the first surfaces or the second surfaces of adjacent substrates is controlled to be no greater than
