Method for detecting stress migration properties

A device and method are provided for detecting stress migration properties of a semiconductor module mounted in a housing. A stress migration test (SMT) structure is formed in the semiconductor module. An integrated heating (IH) device is formed within or in direct proximity to the SMT structure. The SMT structure includes a first interconnect region in a first interconnect layer, a second interconnect region in a second interconnect layer, and a connecting region electrically connecting the interconnect regions through a first insulating layer. The IH device includes a heating interconnect region through which a heating current flows. The heating interconnect region is within or outside the first or second interconnect region or connecting region. When the heating current is applied, a measurement voltage is applied to the SMT structure, and a current through the SMT structure is measured to detect stress migration properties of the semiconductor module.
