    摘要: A general process is described for filling a hole or trench at the surface of an integrated circuit without trapping voids within the filler material. A particular application is the filling of a trench with copper in order to form damascene wiring. First, a seed layer is deposited in the hole or trench by means of PVD. This is then followed by a sputter etching step which removes any overhang of this seed layer at the mouth of the trench or hole. A number of process variations are described including double etch/deposit steps, varying pressure and voltage in the same chamber to allow sputter etching and deposition to take place without breaking vacuum, and reduction of contact resistance between wiring levels by reducing via depth.

    摘要: A method for forming a semiconductor structure includes providing a semiconductor substrate; forming a gate dielectric layer on the semiconductor substrate; forming a metal-containing layer on the gate dielectric; and forming a composite layer over the metal-containing layer. The step of forming the composite layer includes forming an un-doped silicon layer substantially free from p-type and n-type impurities; and forming a silicon layer adjoining the un-doped silicon layer. The step of forming the silicon layer comprises in-situ doping a first impurity. (or need to be change to: forming a silicon layer first & then forming un-doped silicon layer) The method further includes performing an annealing to diffuse the first impurity in the silicon layer into the un-doped silicon layer.

    摘要: A method for providing a stacked wafer configuration is provided. The method includes bonding a first wafer to a second wafer. A filler material is applied in a gap formed along edges of the first wafer and the second wafer. The filler material provides support along the edges during a thinning and transportation process to help reduce cracking or chipping. The filler material may be cured to reduce any bubbling that may have occurred while applying the filler material. Thereafter, the second wafer may be thinned by grinding, plasma etching, wet etching, or the like. In some embodiments of the present invention, this process may be repeated multiple times to create a stacked wafer configuration having three or more stacked wafers.
