A method for forming device structures having a variation in electrical conductivity includes forming a device structure and a radiation absorbing layer overlying the device structure. The radiation absorbing layer has a spatial variation and radiation absorbing characteristics, such that upon irradiating the device structure, the radiation absorbing layer attenuates the intensity of the radiation so that a variation in dopant activation takes place within the device structure. Accordingly, device structures are formed having a variation in electrical resistance independent of the physical size of the device structures.

A method (and semiconductor device) of fabricating a semiconductor device eliminates shallow trench isolation (STI) recess in embedded SiGe p-type field effect transistor (pFET) structures. This increases device performance by improving isolation and decreasing leakage current caused by SiGe facet growth and silicide encroachment at the STI. A mask is selectively formed over the STI and adjacent nFET regions to protect them during formation (e.g., reactive ion etching (RIE)) of the embedded source/drain (S/D) regions of the pFET. The mask also extends over the STI edge by a predetermined distance to cover a portion of the embedded S/D region disposed between the STI and gate structure. This helps protect or isolate the STI region during SiGe layer formation in the defined embedded S/D regions.

The invention describes a novel test structure and process to create the structure for performing automatic dynamic stress testing of PMOS devices for Negative Bias Temperature Instability (NB TI). The invention consists of an integrated inverter, two integrated electronic switches for switching from stress mode to device DC characterization measurement mode, and a PMOS FET device under test (DUT). The inverter assures the proper 180 degree phase relationship between the test device source and gate voltage while the imbedded electronic switches provide isolation of the test device during DC characterization testing. Another embodiment of the invention enables the testing of multiple devices under test (DUTs).
