Abstract: A thermo-mechanical cleavable structure is provided and may be used as a programmable fuse for integrated circuits. As applied to a programmable fuse, the thermo-mechanical cleavable structure includes an electrically conductive cleavable layer adjacent to a thermo-mechanical stressor. As electricity is passed through the cleavable layer, the cleavable layer and the thermo-mechanical stressor are heated and gas evolves from the thermo-mechanical stressor. The gas locally insulates the thermo-mechanical stressor, causing local melting adjacent to the bubbles in the thermo-mechanical stressor and the cleavable structure forming cleaving sites. The melting also interrupts the current flow through the cleavable structure so the cleavable structure cools and contracts. The thermo-mechanical stressor also contracts due to a phase change caused by the evolution of gas therefrom. As the thermo-mechanical cleavable structure cools, the cleaving sites expand causing gaps to be permanently formed therein.

Abstract: A method of modulating grain size in a polysilicon layer and devices fabricated with the method. The method includes forming the layer of polysilicon on a substrate; and performing an ion implantation of a polysilicon grain size modulating species into the polysilicon layer such that an average resultant grain size of the implanted polysilicon layer after performing a pre-determined anneal is higher or lower than an average resultant grain size than would be obtained after performing the same pre-determined anneal on the polysilicon layer without a polysilicon grain size modulating species ion implant.

Abstract: A structure and a method for operating the same. The method comprises providing a resistive/reflective region on a substrate, wherein the resistive/reflective region comprises a material having a characteristic of changing the material's reflectance due to the material absorbing heat; sending an electric current through the resistive/reflective region so as to cause a reflectance change in the resistive/reflective region from a first reflectance value to a second reflectance value different from the first reflectance value; and optically reading the reflectance change in the resistive/reflective region.

Abstract: A method is presented for measuring and monitoring the mechanical stress at the device level which occurs intrinsically during the fabrication process or which is induced via extrinsic means. The method applies the fact that the current-voltage (I-V) characteristics of a diode change as the diode is subjected to mechanical stress. The method is applicable to monitoring stress at the microscopic and device levels at various stages in the semiconductor wafer fabrication process. Apparatus for implementing the method is also presented.
