An approach for detecting sudden changes in acceleration in a semiconductor device or semiconductor package containing the semiconductor device is disclosed. In one embodiment, a piezoelectric sensor is embedded in a semiconductor die. The piezoelectric sensor is configured to sense a mechanical force applied to the semiconductor die. An excessive force indicator is coupled to the piezoelectric sensor. The excessive force indicator is configured to generate an excessive force indication in response to the piezoelectric sensor sensing that the mechanical force applied to the semiconductor die has exceeded a predetermined threshold indicative of an excessive mechanical force.

A self-healing crack stop structure and methods of manufacture are disclosed herein. The structure comprises a crack stop structure formed in one or more dielectric layers and surrounding an active region of an integrated circuit chip. The crack stop comprises self healing material which, upon propagation of a crack, is structured to seal the crack and prevent further propagation of the crack.
