An integrated circuit (IC) packaging arrangement for surface mounting of the IC includes a package body that encapsulates one or more IC dies. The package body according to some embodiments has rectangular aspect ratio with a length dimension and a width dimension of different size. The IC packaging according to some embodiments includes leadless surface-mount electrical contacts. According to some embodiments, the leadless surface-mount contacts are situated in clusters at opposite ends of the length dimension of the IC body.

The present invention discloses a method including providing a substrate; forming a lower conductor over the substrate; forming a conducting nanostructure over the lower conductor; forming a thin dielectric over the conducting nanostructure; and forming an upper conductor over the thin dielectric. The present invention further discloses a device including a substrate; a lower conductor located over the substrate; a conducting nanostructure located over the lower conductor; a thin dielectric located over the conducting nanostructure; and an upper conductor located over the thin dielectric.

Apparatus for an on-chip decoupling capacitor. The capacitor includes a bottom electrode that consist of nanostructures deposited over a planarized metal, a dielectric material deposited over the nanostructures, and a top electrode deposited over the dielectric material. The shape of the bottom electrode is tunable by modulating the diameter and/or the length of the nanostructures to produce an increase in capacitance without increasing the footprint of the on-chip decoupling capacitor.

Method and device for on-chip decoupling capacitor using nanostructures as bottom electrode

A method of vertically stacking wafers is provided to form three-dimensional (3D) wafer stack. Such method comprising: selectively depositing a plurality of metallic lines on opposing surfaces of adjacent wafers; bonding the adjacent wafers, via the metallic lines, to establish electrical connections between active devices on vertically stacked wafers; and forming one or more vias to establish electrical connections between the active devices on the vertically stacked wafers and an external interconnect. Metal bonding areas on opposing surfaces of the adjacent wafers can be increased by using one or more dummy vias, tapered vias, or incorporating an existing copper (Cu) dual damascene process.
