  • Patent number: 9188625
    Abstract: Semiconductor device test structures and methods are disclosed. In a preferred embodiment, a test structure includes a feed line disposed in a first conductive material layer, and a stress line disposed in the first conductive material layer proximate the feed line yet spaced apart from the feed line. The stress line is coupled to the feed line by a conductive feature disposed in at least one second conductive material layer proximate the first conductive material layer.
    Type: Grant
    Filed: December 5, 2013
    Date of Patent: November 17, 2015

  • Patent number: 7763520
    Abstract: A capacitor device includes a substrate, a first conductive structure, a second conductive structure, a dielectric layer structure, and a recess in the substrate. The first and second conductive structures are disposed on opposite sides of the dielectric layer structure, and the dielectric layer structure extends in a meander-shaped manner in a cross-section through the recess.

  • Patent number: 7233053
    Abstract: To fabricate an integrated semiconductor product with integrated metal-insulator-metal capacitor, first of all a dielectric auxiliary layer (6) is deposited on a first electrode (2, 3, 5). This auxiliary layer (6) is then opened up (15) via the first electrode. Then, a dielectric layer (7) is produced, and the metal track stack (8, 9, 10) for the second electrode is then applied to the dielectric layer (6). This is followed by the patterning of the metal-insulator-metal capacitor using known etching processes. This makes it possible to produce dielectric capacitor layers of any desired thickness using materials which can be selected as desired. In particular, this has the advantage that via etches can be carried out significantly more easily than in the prior art, since it is not necessary to etch through the residual dielectric capacitor layer above the metal tracks.

  • Patent number: 6924725
    Abstract: A coil apparatus includes a coil trace, a semiconductor substrate and a dielectric layer arranged on the semiconductor substrate, at least parts of the coil trace being arranged above a recess in the dielectric layer. The coil apparatus further includes a support apparatus arranged in the recess and connected to the coil trace for mechanically supporting the coil trace. The supporting apparatus is preferably a conductive column that is not removed when the recessed is formed in the dielectric layer.
