A method of fabricating a surface enhanced Raman scattering (SERS) substrate. In one embodiment, the method has the steps of simultaneously evaporating a metal at a first evaporation rate and a polymer at a second evaporation rate different from the first evaporation rate, to form a nanocomposite of the metal and the polymer, depositing the nanocomposite onto a substrate, and applying an etching process to the deposited nanocomposite on the substrate to remove the polymer material, thereby forming an SERS substrate.

A method of detecting local mechanical stress in integrated devices is provided, the method comprising: enabling the detection of a photovoltage difference between a scan probe device and a surface portion of an integrated device, the scan probe device being configured to deflect in response to the photovoltage difference; measuring the deflection of the scan probe device in response to the photovoltage difference between the scan probe device and the surface portion of the integrated device; and calculating a local stress level within the integrated device by determining a local work function of the surface portion of the integrated device based upon the deflection of the scan probe device.
