Patent number: 8018017Abstract: 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.Type: GrantFiled: January 26, 2005Date of Patent: September 13, 2011Assignee: International Business Machines CorporationInventors: Fen Chen, Cathryn J.

Patent number: 7902625Abstract: A metal gate thermocouple is provided. The thermocouple is configured to measure local temperatures of a device. The thermocouple is a passive device which senses temperature using the thermoelectric principle that when two dissimilar electrically conductive materials are joined, an electrical potential (voltage) is developed between the two materials. The voltage between the materials varies with the temperature of the junction (joint) between the materials. The thermocouple device includes a first conductor comprising a first material formed over a thin oxide layer or a shallow trench isolation (STI) structure and a second conductor comprising a second material formed over the thin oxide layer or the STI structure. The second conductor overlaps with the first conductor to form a thermocouple junction or dimension at least more than an alignment tolerance. The first and second materials are chosen such that the thermocouple junction formed between them exhibits a non-zero Seebeck coefficient.Type: GrantFiled: April 21, 2008Date of Patent: March 8, 2011Assignee: International Business Machines CorporationInventors: Brent A.
