A method of forming an interposer includes providing a semiconductor substrate, the semiconductor substrate having a front surface and a back surface opposite the front surface; forming one or more through-silicon vias (TSVs) extending from the front surface into the semiconductor substrate; forming an inter-layer dielectric (ILD) layer overlying the front surface of the semiconductor substrate and the one or more TSVs; and forming an interconnect structure in the ILD layer, the interconnect structure electrically connecting the one or more TSVs to the semiconductor substrate.

A method of forming a device includes printing conductive patterns on a dielectric sheet to form a pre-ink-printed sheet, and bonding the pre-ink-printed sheet onto a side of a substrate. The conductive feature includes a through-substrate via extending from a first major side of the substrate to a second major side of the substrate opposite the first major side. A conductive paste is then applied to electrically couple conductive patterns to a conductive feature in the substrate.

An under-bump metallization (UBM) structure for a semiconductor device is provided. The UBM structure has a center portion and extensions extending out from the center portion. The extensions may have any suitable shape, including a quadrangle, a triangle, a circle, a fan, a fan with extensions, or a modified quadrangle having a curved surface. Adjacent UBM structures may have the respective extensions aligned or rotated relative to each other. Flux may be applied to a portion of the extensions to allow an overlying conductive bump to adhere to a part of the extensions.

A primary supramolecular structure is described. The primary supramolecular structure has a shape of ring-like disk. The shape of ring-like disk has a diameter of about 10 nanometers to about 60 nanometers. The mentioned primary supramolecular structure is formed by self-assembly of amphiphilic conjugate molecules. Moreover, a secondary supramolecular structure is described. The secondary supramolecular structure has a shape of ring-like disk. The shape of ring-like disk has a diameter of about 100 nanometers to about 300 nanometers. The mentioned secondary supramolecular structure is formed by self-assembly of amphiphilic conjugate molecules hybrid with metal alkoxides or non-metal alkoxides.

A method is disclosed for controlling the sheet resistance of copper trenches formed on semiconductor wafers. The method includes forming a plurality of copper-filled trenches on a wafer, measuring the sheet resistance of each of the plurality of copper-filled trenches, and comparing the measured sheet resistance values to a predetermined sheet resistance value. Photolithography steps performed on subsequent wafers are adjusted according to a difference between the measured sheet resistance values and the predetermined value. In one embodiment, this adjustment takes the form of adjusting a photolithographic extension exposure energy to thereby adjust the cross-section of the resulting trenches.
