  • Detection Device Having Increased Detection Rate, and Method for Quick Detection of Biological Molecules
    Publication number: 20120071365
    Abstract: A biological molecule detection device that includes a detection array, arranged on a body and having one or more probes for detecting corresponding electrically charged molecules, wherein a time varying electric field generating circuit is provided for generating at least one time varying electric field around the detection array within the detection region. The time varying electric field moves the electrical charged molecules repeatedly back and forth over the probes, thus providing increased opportunities for interaction and speeding the detection process.
    Type: Application
    Filed: November 29, 2011
    Publication date: March 22, 2012
    Applicant: STMicroelectronics S.r.l.
    Inventors: Michele PALMIERI, Alessandra FISCHETTI

  • Process for manufacturing micromechanical components in a semiconductor material wafer with reduction in the starting wafer thickness
    Patent number: 6689627
    Abstract: A process for manufacturing components in a multi-layer wafer, including the steps of: providing a multi-layer wafer comprising a first semiconductor material layer, a second semiconductor material layer (, and a dielectric material layer arranged between the first and the second semiconductor material layer; and removing the first semiconductor material layer initially by mechanically thinning the first semiconductor material layer, so as to form a residual conductive layer, and subsequently by chemically removing the residual conductive layer. In one application, the multi-layer wafer is bonded to a first wafer of semiconductor material, with the second semiconductor material layer facing the first wafer, after micro-electromechanical structures have been formed in the second semiconductor material layer of the multi-layer wafer.
