Abstract:
A method of forming a through-silicon-via (TSV) opening includes forming a TSV opening through a substrate. A recast of a material of the substrate on sidewalls of the TSV opening is removed with a first chemical. The sidewalls of the TSV opening are cleaned with a second chemical by substantially removing a residue of the first chemical.

The present disclosure provides a method for fabricating a semiconductor device. The method includes providing a semiconductor substrate having a first region and a second region, forming a high-k dielectric layer over the semiconductor substrate, forming a first metal layer and a first silicon layer by an in-situ deposition process, patterning the first silicon layer to remove a portion overlying the second region, patterning the first metal layer using the patterned first silicon layer as a mask, and removing the patterned first silicon layer including applying a solution. The solution includes a first component having an [F—] concentration greater than 0.01 M, a second component configured to adjust a pH of the solution from about 4.3 to about 6.7, and a third component configured to adjust a potential of the solution to be greater than −1.4 volts.
Abstract:
In some embodiments, a method of doping a semiconductor wafer disposed on a pedestal electrode in an inductive plasma chamber includes generating a plasma having a first voltage with respect to ground in the inductive plasma chamber, and applying a radio frequency (RF) voltage with respect to ground to the pedestal electrode in the inductive plasma chamber. The positive RF voltage is based on the first voltage of the plasma.
Abstract:
A retainer ring and a method of using the retainer ring are provided. The retainer ring has openings along a bottom surface. Grooves encompass the openings and extend to an interior portion of the retainer ring wherein a semiconductor wafer may be held. In operation, a semiconductor wafer is placed inside the retainer ring. As the retainer ring and the semiconductor wafer are moved relative to an underlying polishing pad, slurry is dispensed through the openings in the retainer ring. The grooves in the retainer ring allow the slurry to flow from the openings to the interior portion of the retainer ring and the semiconductor wafer.
