  • Patent number: 9911737
    Abstract: An integrated circuit includes a substrate with first and second cells having first and second FDSOI field-effect transistors. There are first and second ground planes, a buried oxide layer and first and second wells, under the ground planes. The first well and the first ground plane have the same doping and the second well and the second ground plane have the same doping. The first and second cells are adjoined and their transistors are aligned in a first direction. The wells of the first cell and the first well of the second cell are doped opposite of the second well. A control device applies a first electrical bias to the wells with the first doping and a second electrical bias to the well with the second doping. The transistors of the first cell and second cell have different threshold voltage levels.

  • Publication number: 20180047440
    Abstract: An autocorrective writing to a multiport static random access memory device is performed on at least one multiport static random access memory cell circuit. A first datum is written to the multiport static random access memory cell circuit and a second datum stored in the circuit is read from the multiport static random access memory cell subsequent to writing. The first and second data are compared. In response to the results of that comparison, an operation to rewriting the first datum to the circuit along with application of a write assist mechanism is selectively performed.

  • Patent number: 9870947
    Abstract: Electronic devices are manufactured using a collective (wafer-scale) fabrication process. Electronic chips are mounted onto one face of a collective substrate wafer. A collective flexible sheet made of a heat-conductive material comprising a layer containing pyrolytic graphite is fixed to extend over a collective region extending over the electronic chips and over the collective substrate wafer between the electronic chips.

  • Patent number: 9859319
    Abstract: A color image sensor including an array of pixels is formed in a semiconductor layer having a back side that receives an illumination. Insulated conductive walls penetrate into the semiconductor layer from the back side and separate the pixels from one another. For each pixel, a color pixel penetrates into from 5 to 30% of a thickness of the semiconductor layer from the back side and occupies at least 90% of the surface area delimited by the walls. An electrically-conductive layer extends from the lateral wall of the filter all the way to the walls.

    Abstract: An integrated electronic device is supported by a substrate of a silicon on insulator type. At least one transistor is formed in and on a semiconductor film of the substrate. The transistor includes a drain region and a source region of a first conductivity type and a substrate (body) region of a second conductivity type lying under a gate region. An extension region laterally continues the substrate (body) region beyond the source and drain regions and borders, in contact with, the source region through a border region having the first conductivity type. This supports formation of an electrical connection of the source region and the substrate (body) region.

  • Patent number: 9838572
    Abstract: The method includes for each current pair of first and second successive video images determining movement between the two images. The determining includes a phase of testing homography model hypotheses on the movement by a RANSAC type algorithm operating on a set of points in the first image and first assumed corresponding points in the second image so as to deliver one of the homography model hypothesis that defines the movement. The test phase includes a test of first homography model hypotheses of the movement obtained from a set of second points in the first image and second assumed corresponding points in the second image. At least one second homography model hypothesis is obtained from auxiliary information supplied by an inertial sensor and representative of a movement of the image sensor between the captures of the two successive images of the pair.
