  • Patent number: 9871008
    Abstract: Low Q associated with passive components of monolithic integrated circuits (ICs) when operated at microwave frequencies can be avoided or mitigated using high resistivity (e.g., ?100 Ohm-cm) semiconductor substrates and lower resistance inductors for the IC. This eliminates significant in-substrate electromagnetic coupling losses from planar inductors and interconnections overlying the substrate. The active transistor(s) are formed in the substrate proximate the front face. Planar capacitors are also formed over the front face of the substrate. Various terminals of the transistor(s), capacitor(s) and inductor(s) are coupled to a ground plane on the rear face of the substrate using through-substrate-vias to minimize parasitic resistance. Parasitic resistance associated with the planar inductors and heavy current carrying conductors is minimized by placing them on the outer surface of the IC where they can be made substantially thicker and of lower resistance.

  • Patent number: 9837299
    Abstract: Methods of forming 3-D ICs with integrated passive devices (IPDs) include stacking separately prefabricated substrates. An active device (AD) substrate has contacts on its upper portion. A ground plane is located between the AD substrate and an IPD substrate. The ground plane provides superior IPD to AD cross-talk attenuation.

  • Patent number: 9698131
    Abstract: Methods of forming 3-D ICs with integrated passive devices (IPDs) include stacking separately prefabricated substrates coupled by through-substrates-vias (TSVs). An active device (AD) substrate has contacts on its upper portion. An isolator substrate is bonded to the AD substrate so the TSVs in the isolator substrate are coupled to the contacts on the AD substrate. An IPD substrate is bonded to the isolator substrate so that TVs therein are coupled to an interconnect zone on the isolator substrate and/or TSVs therein. The IPDs of the IPD substrate are coupled by TSVs in the IPD and isolator substrates to devices in the AD substrate. The isolator substrate provides superior IPD to AD cross-talk attenuation while permitting each substrate to have small high aspect ratio TSVs, thus facilitating high circuit packing density and efficient manufacturing.

  • Patent number: 8329579
    Abstract: Through substrate vias (TSVs) are provided after substantially all high temperature operations needed to form a device region of a first thickness proximate the front surface of a substrate wafer by: (i) from the front surface, forming comparatively shallow vias of a first aspect ratio containing first conductors extending preferably through the first thickness but not through the initial wafer thickness, (ii) removing material from the rear surface to form a modified wafer of smaller final thickness with a new rear surface, and (iii) forming from the new rear surface, much deeper vias of second aspect ratios beneath the device region with second conductors therein contacting the first conductors, thereby providing front-to-back interconnections without substantially impacting wafer robustness during manufacturing and device region area. Both aspect ratios are desirably about ?40, usefully ?10 and preferably ?5.
