Abstract
In one embodiment, an integrated circuit packaging structure includes a first metal adhesion layer formed under a lid and a second metal adhesion layer formed over a substrate. The lid includes a free surface that may move a small amount without cracking. The second metal adhesion layer is configured such that its outer end does not extend past the free surface of the lid to minimize crack formation.
