A method of stacking semiconductor dies includes attaching a lower semiconductor die to a base substrate with an adhesive layer and attaching an upper semiconductor die to the lower semiconductor die with another adhesive layer. A thermo-compression bonding technique is applied to the upper semiconductor die to cure the adhesive layers and to bond the upper semiconductor die to the lower semiconductor die.

Methods of stacking semiconductor dies

Wafer level packages are provided. The wafer level package includes alignment marks disposed at a first surface of a protection wafer, a semiconductor die disposed on the first surface of the protection wafer to be spaced apart from the alignment marks, a first photosensitive dielectric layer covering the semiconductor die and having a flat top surface, and a second dielectric layer covering the flat top surface of the first photosensitive dielectric layer. Redistribution lines are disposed between the first photosensitive dielectric layer and the second dielectric layer and electrically connected to the semiconductor die through first opening portions penetrating the first photosensitive dielectric layer. Outer connectors are disposed on the second dielectric layer and electrically connected to the redistribution lines through second opening portions penetrating the second dielectric layer.
