  • Biosensor capacitor
    Patent number: 8986523
    Abstract: A biosensor capacitor, including a dielectric layer; a first metal layer in the dielectric layer; a passivation layer over the dielectric layer and the first metal layer; an isolation layer over the passivation layer; a probe DNA electrode connected to the first metal layer; a counter electrode connected to the first metal layer wherein the counter electrode forms an enclosure around the probe DNA electrode; and a bond pad connected to the first metal layer.
    Type: Grant

  • Biosensors integrated with a microfluidic structure
    Patent number: 8674474
    Abstract: A biosensor with a microfluidic structure surrounded by an electrode and methods of forming the electrode around the microfluidic structure of the biosensor are provided. A method includes forming a gate or electrode in a first layer. The method further includes forming a trench in a second layer. The method further includes forming a first metal layer in the trench such that the first metal layer is in electrical contact with the gate or the electrode. The method further includes forming a sacrificial material in the trench. The method further includes forming a second metal layer over the sacrificial material and in contact with the first metal layer. The method further includes removing the sacrificial material such that a microfluidic channel is formed surrounded by the first and the second metal layers.

  • Anti-blooming pixel sensor cell with active neutral density filter, methods of manufacture, and design structure
    Patent number: 8618588
    Abstract: A method of preventing blooming in a pixel array includes affecting an amount of light that impinges on a photoelectric conversion element by adjusting a transmissivity of an electrochromic element based on an output of the photoelectric conversion element.
