  • Fusion-bond electrical feed-through
    Patent number: 5929498
    Abstract: A semiconductor device has a flexible structure bonded to a semiconductor substructure to form a cavity. The flexible structure is bonded over a conducting feed-through without the feed-through interfering with a hermetic seal formed by bonding. One embodiment of the device includes depressions that contain edges of a diffused feed-through so that imperfections at the edge of the diffusion do not interfere with bonding. The flexible structure is bonded to elevated areas thus hiding the imperfections. In one embodiment, a first elevated region is surrounded by a second elevated region, and diffusion for the feed-through extends from an active region in the cavity across the first elevated region with edges of the diffusion being between the first and second elevated regions. The flexible structure can thus bond to the first and second elevated regions without interference from the edge of the diffused feed-through.

  • Exceedance counting integrating photo-diode array
    Patent number: 4679215
    Abstract: The use of a comparator and counter associated, on-chip, with each photo-element of an array. Sensing each photo-element without discharging it and allowing each photo-element to accumulate a charge which is large relative to noise variations. These features result in a photo-detector with large signal-to-noise ratios.
