  • Publication number: 20090113357
    Abstract: A method, device and system for monitoring ionizing radiation, and design structures for ionizing radiation monitoring devices. The method including: collecting an ionizing radiation induced charge collected by the depletion region of a diode formed in a silicon layer below an oxide layer buried below a surface of a silicon substrate; and coupling a cathode of the diode to a precharged node of a clocked logic circuit such that the ionizing radiation induced charge collected by a depletion region of the diode will discharge the precharged node and change an output state of the clocked logic circuit.

  • Patent number: 7227239
    Abstract: A resettable fuse device is fabricated on one surface of a semiconductor substrate (10) and includes: a gate region (20) having first and second ends; a source node (81) formed in proximity to the first end of the gate region; an extension region (52) formed to connect the source node to the first end of the gate region; and a drain node (80) formed in proximity to the second end of the gate region and separated from the gate region by a distance (D) such that upon application of a predetermined bias voltage to the drain node a connection between the drain node and the second end of the gate region is completed by junction depletion. A gate dielectric (30) and a gate electrode (40) are formed over the gate region. Current flows between the source node and the drain node when the predetermined bias is applied to both the drain node and the gate electrode.

  • Publication number: 20040251514
    Abstract: The present invention relates to metal-insulator-metal (MIM) capacitors and field effect transistors (FETs) formed on a semiconductor substrate. The FETs are formed in Front End of Line (FEOL) levels below the MIM capacitors which are formed in upper Back End of Line (BEOL) levels. An insulator layer is selectively formed to encapsulate at least a top plate of the MIM capacitor to protect the MIM capacitor from damage due to process steps such as, for example, reactive ion etching. By selective formation of the insulator layer on the MIM capacitor, openings in the inter-level dielectric layers are provided so that hydrogen and/or deuterium diffusion to the FETs can occur.
