摘要： The invention relates to a flip-chip integrated circuit package of the ball array type, wherein: the underside of the package includes a plurality of receiving pads for signal, ground and solder balls; stacks of signal and ground vias, electrically connected to respective receiving pads, pass vertically through the package's dielectric body forming a quasi-coaxial structure. In an upper part of the package body: the signal vias are electrically connected to a lesser number of signal conductive bumps protruding from the upper surface of the package's dielectric body; and at least two ground vias are connected by means of conductive projections to respective ground conductive bumps, forming a ring around the signal conductive bumps.

摘要： In an active pixel sensor comprising a photodiode Dp, a memory node MN and a readout node SN, the memory node being provided to contain the charge generated by the photodiode at the end of an integration period allowing an integration in global shutter mode and a correlated double sampling, it is envisaged to carry out, in each integration period, at least one transfer {circle around (2)} of charge from the photodiode to the memory node followed by clipping {circle around (3)} of the amount of charge contained in the memory node at an intermediate voltage t1 after the start of the integration period but before a last transfer of charge {circle around (4)} to the memory node at the end of the integration period. The pixels are subsequently read out, row by row, by correlated double sampling CDS. The one or more intermediate transfers, with clipping, to the memory node during the integration period allow the dynamic range of the sensor to be extended to high levels of ambient light while retaining good sensitivity to low levels of ambient light.

摘要： An intra-oral dental radiological image sensor is mechanically reinforced by two front RA and rear RB mechanical reinforcing plates each inserted between a respective face of an image capture module and a respective front 20A and rear 20B shell bottom of a casing. The front reinforcing plate is a solid plate, made of material transparent to X rays, covering the photosensitive front face (scintillator) of the module, and harder than the front shell. The rear plate, less thick than the front plate, is harder than the rear shell and comprises an opening O provided to surround, without covering them, components present on the rear face of the module, under a rear shell dome.

摘要： In a hermetic integrated-circuit package, the peripheral wall that bounds the cavity 2 containing the integrated circuit has, all the length of the peripheral wall, a surface containing a relief, which is defined by a raised planar zone z1, on the side inside the package of the cavity, and a recessed zone z2, on the exterior of the raised planar zone. The planar zone makes direct contact with the closing plate 6 of the package, without interposition of adhesive, over the entire length of the peripheral wall, except where planarity defects prevent the contact. The recessed zone does not make direct contact with the closing plate, and contains an adhesive bead that joins the closing plate and the upper portion of the peripheral wall over all the peripheral length of the latter. The adhesive bead 9 has a surface Se in open air between the closing plate and the recessed zone, on the exterior side of the package. This surface serves as an exchange surface with the exterior atmosphere of the package, in case of adhesive degassing.

摘要： The invention proposes a method for distributing a signal to each block Bj of a series of N adjacent blocks of identical design in an electronic circuit. It proposes, in an identical fashion for each of the N blocks, placing a timing delay circuit MUX-DELj on the path for conveying a signal Sc from the input INcj of the block to an internal electrical node Ndj of the block for this signal Sc; providing for the timing delay circuit to supply N delayed signals corresponding to N different timing delays Δf1, . . . Δfj, . . . ΔfN separated by an increment of elementary duration Δt that corresponds to the elementary delay Δt for transit of a block introduced into a conductive line; and selecting the delayed signal corresponding to the applicable timing delay according to the block in question, by means of an index signal propagated through the N blocks, and which is incremented or decremented on passage through each block.

摘要： The invention relates to time-delay and signal-integration linear image sensors (or TDI sensors). According to the invention, a pixel comprises a succession of several insulated gates covering a semiconducting layer, the gates of one pixel being separated from one another and separated from the gates of an adjacent pixel of another line by narrow uncovered gaps of a gate and comprising a doped region of a second type of conductivity covered by a doped superficial region of the first type; the superficial regions are kept at one and the same reference potential; the width of the narrow gaps between adjacent gates is such that the internal potential of the region of the second type is modified in the whole width of the narrow gap when a gate sustains the alternations of potential necessary for the transfer of charges from one pixel to the following one.

摘要： The invention relates to time-delay and charge integration image sensors employing active CMOS technology pixels. The sensor comprises N rows of pixels and each pixel of generally square shaped comprises two (though possibly also three or four) photodiodes and charge storage nodes, having means for transferring charges from each photodiode to one or other of the storage nodes. Control of transfer from the photodiodes to one then the other of the storage nodes is carried out in such a way that one storage node receives in succession, during two successive phases of a periodic cycle, the charges from two photodiodes that have seen the same image portion during the two phases. The charges received by one of the storage nodes during the first phase is added to the charges received by the other storage node in the following phase.
