Abstract
Die () and/or undiced wafers and/or multichip modules (MCMs) are attached on top of an interposer () or some other structure (e.g. another integrated circuit) and are covered by an encapsulant (). Then the interposer is thinned from below. Before encapsulation, a layer () more rigid than the encapsulant is formed on the interposer around the die to reduce or eliminate interposer dishing between the die when the interposer is thinned by a mechanical process (e.g. CMP). Other features are also provided.
