Abstract: Provided are a thermal interface material layer and a package-on-package device including the same. The package-on-package device may include a thermal interface material layer interposed between lower and upper semiconductor packages and configured to have a specific physical property. Accordingly, it is possible to prevent a crack from occurring in a lower semiconductor chip, when a solder ball joint process is performed to mount the upper semiconductor package on the lower semiconductor package.
