Patent ID: 7189642

Claim:
A method of fabricating an interconnect or a semiconductor component, comprising: providing a semiconductor component, the component comprising a monocrystalline semiconductor material having a pair of opposing sides, the component comprising a front side outwardly of one of the opposing sides of the monocrystalline semiconductor material and a back side outwardly of the other of the opposing sides of the monocrystalline semiconductor material, the component further comprising a conductive-material layer proximate the front side; forming an opening which extends from the front side to the back side and thus extends entirely through the semiconductor component, the opening having sidewalls and extending through the conductive-material layer; depositing a first material along the sidewalls of the opening to narrow the opening, the depositing utilizing one or more cycles of a process which forms less than or equal to about 10 Å of the first material per cycle and which exposes the component to a temperature of less than or equal to about 200° C.; forming a solder-wetting material within the opening and along the first material; and forming solder along the solder-wetting material to fill the opening with solder; the solder within the opening electrically connecting with the conductive-material layer.
