    Abstract: The present invention relates to a method for minimizing breakage of wafers during or after a wafer thinning process. A method of forming a rounded edge to the portion of a wafer remaining after surface grinding process is provided. The method comprises providing a semiconductor wafer having an edge and forming a recess in the edge of the wafer using any suitable mechanical or chemical process. The method further comprises forming a substantially continuous curved shape for at least the edge of the wafer located above the recess. Advantageously, the shape of the wafer is formed prior to the backside grind process to prevent problems caused by the otherwise presence of a sharp edge during the backside grind process.

    Abstract: A structure. The structure includes a substrate, a resistive/reflective region on the substrate, and a light source/light detecting and/or a sens-amp circuit configured to ascertain a reflectance and/or resistance change in the resistive/reflective region. The resistive/reflective region includes a material having a characteristic of the material's reflectance and/or resistance being changed due to a phase change in the material. The resistive/reflective region is configured to respond, to an electric current through the resistive/reflective region and/or a laser beam projected on the resistive/reflective region, by the phase change in the material which causes a reflectance and/resistance change in the resistive/reflective region from a first reflectance and/or resistance value to a second reflectance and/or resistance value different from the first reflectance and/or resistance value.
