An embodiment comprises a dielectric layer and contacts extending through the dielectric layer to connect to conductive regions. A contact barrier layer is formed between the conductive regions and the contacts by electroless plating the conductive regions after openings have been formed through the dielectric layer for the contact. The contact barrier layer is then treated to fill the grain boundary of the contact barrier layer, thereby improving the contact resistance. In another embodiment, the contact barrier layer is formed on the conductive regions by electroless plating prior to the formation of the dielectric layer.

    Abstract: By forming thermocouples in a contact structure of a semiconductor device, respective extension lines of the thermocouples may be routed to any desired location within the die, without consuming valuable semiconductor area in the device layer. Thus, an appropriate network of measurement points of interest may be provided, while at the same time allowing the application of well-established process techniques and materials. Hence, temperature-dependent signals may be obtained from hot spots substantially without being affected by design constraints in the device layer.
