  • Publication number: 20240098959
    Abstract: A method includes etching a first semiconductor fin and a second semiconductor fin to form first recesses. The first and the second semiconductor fins have a first distance. A third semiconductor fin and a fourth semiconductor fin are etched to form second recesses. The third and the fourth semiconductor fins have a second distance equal to or smaller than the first distance. An epitaxy is performed to simultaneously grow first epitaxy semiconductor regions from the first recesses and second epitaxy semiconductor regions from the second recesses. The first epitaxy semiconductor regions are merged with each other, and the second epitaxy semiconductor regions are separated from each other.

  • Publication number: 20220384245
    Abstract: Methods of forming a slurry and methods of performing a chemical mechanical polishing (CMP) process utilized in manufacturing semiconductor devices, as described herein, may be performed on semiconductor devices including integrated contact structures with ruthenium (Ru) plug contacts down to a semiconductor substrate. The slurry may be formed by mixing a first abrasive, a second abrasive, and a reactant with a solvent. The first abrasive may include a first particulate including titanium dioxide (TiO2) particles and the second abrasive may include a second particulate that is different from the first particulate. The slurry may be used in a CMP process for removing ruthenium (Ru) materials and dielectric materials from a surface of a workpiece resulting in better WiD loading and planarization of the surface for a flat profile.
