Abstract
An integrated circuit includes active circuitry disposed at a surface of a semiconductor body and an interconnect region disposed above the semiconductor body. A thermoelectric material is disposed in an upper portion of the interconnect region away from the semiconductor body. The thermoelectric material is configured to deliver electrical energy when exposed to a temperature gradient. This material can be used, for example, in a method for detecting the repackaging of the integrated circuit after it has been originally packaged.
