  • Patent number: 11049764
    Abstract: A method for fabricating a semiconductor device comprises: providing a substrate having a top surface; forming a bottom metal embedded in the substrate; forming a first etch stop layer, a first dielectric layer, a second etch stop layer and a second dielectric layer sequentially stacked on the top surface of the substrate; forming a semiconductor element disposed on the first etch stop layer, wherein the semiconductor element comprises a top plate and an etch stop pad disposed on the top plate; performing a first etching process to form a first partial via and a second partial via penetrating the second dielectric layer, the second etch stop layer and a portion of the first dielectric layer, wherein the first partial via is separated from the bottom metal by the first dielectric layer, and the second partial via is separated from the top plate by the etch stop pad.
    Type: Grant

  • Patent number: 7670438
    Abstract: A method of removing particles from a wafer is provided. The method is adopted after a process for removing unreactive metal of a salicide process or after a salicide process and having oxide residue remaining on a wafer or after a chemical vapor deposition (CVD) process that resulted with particles on a wafer. The method includes performing at least two cycles (stages) of intermediate rinse process. Each cycle of the intermediate rinse process includes conducting a procedure of rotating the wafer at a high speed first, and then conducting a procedure of rotating the wafer at a low speed.
