  • Patent number: 10147637
    Abstract: A method of forming conductive paths and vias is disclosed. In one aspect, patterns of a hard mask layer are transferred into a dielectric layer by etching to form trenches. The trenches define locations for conductive paths of an upper metallization level. At least one trench is interrupted in a longitudinal direction by a block portion of the hard mask layer, the block portion defining the tip-to-tip location of a pair of the conductive paths to be formed. The trenches extend partially through the dielectric layer in regions exposed by the hard mask layer, thereby deepening first and the second holes to extend completely through the dielectric layer. After removing the hard mask layer, the deepened first and second holes and the trenches are filled with a conductive material to form the conductive paths in the trenches and to form the vias in the deepened first and second holes.

  • Patent number: 10141394
    Abstract: The disclosed technology relates to a metal-insulator-metal capacitor (MIMCAP) integrated as part of a back-end-of-line of an integrated circuit (IC). In one aspect, a MIMCAP comprises a first planar electrode having perforations formed therethrough, and a metal-insulator-metal (MIM) stack lining inner surfaces of cavities formed in the perforations and extending into the substrate. The MIMCAP additionally comprises a second electrode having a planar portion and metal extensions extending from the planar portion into the cavities. The first electrode and the planar portion of the second electrode are formed of or comprise planar metal areas of the respective metallization levels, which can be formed by a damascene process, which allows for a reduction of the series resistance. A low aspect ratio can be obtained using one electrode having a 3D-structure (the electrode having extensions extending into the cavities).

  • Patent number: 10141284
    Abstract: The disclosed technology generally relates to semiconductor wafer bonding, and more particularly to direct bonding by contacting surfaces of the semiconductor wafers. In one aspect, a method for bonding a first semiconductor substrate to a second semiconductor substrate by direct bonding is described. The substrates are both provided on their contact surfaces with a dielectric layer, followed by a CMP step for reducing the roughness of the dielectric layer. Then a layer of SiCN is deposited onto the dielectric layer, followed by a CMP step which reduces the roughness of the SiCN layer to the order of 1 tenth of a nanometer. Then the substrates are subjected to a pre-bond annealing step and then bonded by direct bonding, possibly preceded by one or more pre-treatments of the contact surfaces, and followed by a post-bond annealing step, at a temperature of less than or equal to 250° C.

  • Patent number: 10139280
    Abstract: An integrated circuit for an imaging system is disclosed. In one aspect, an integrated circuit has an array of optical sensors, an array of optical filters integrated with the sensors and configured to pass a band of wavelengths onto one or more of the sensors, and read out circuitry to read out pixel values from the sensors to represent an image. Different ones of the optical filters are configured to have a different thickness, to pass different bands of wavelengths by means of interference, and to allow detection of a spectrum of wavelengths. The read out circuitry can enable multiple pixels under one optical filter to be read out in parallel. The thicknesses may vary non-monotonically across the array. The read out, or later image processing, may involve selection or interpolation between wavelengths, to carry out spectral sampling or shifting, to compensate for thickness errors.

  • Publication number: 20180337683
    Abstract: Systems and methods for providing improved linearity and reduced noise in a digital phase-locked loop in which a differential time-to-digital converter is implemented. Digital-to-time converters are used for adjusting a reference clock signal based on a fractional change signal and for adjusting a feedback signal based on another fractional change signal. Each fractional change signal is centered about a midpoint, M, and offset from the midpoint by a fraction, x, such that the fractional change signals can be described as (M+x) and (M?x), respectively. By implementing a differential time-to-digital converter, the sum of delays in each input path is kept constant so that integral non-linearity is improved. Supply sensitivity is also reduced, as the same supply is applied to both differential input paths. Since the differential delay can be both positive and negative, the delay range of a differential digital-to-time converter is half that of a single input digital-to-time converter.
