  • Publication number: 20230352559
    Abstract: A dummy gate structure may be formed for a semiconductor device. The dummy gate structure may be formed from an amorphous polysilicon layer. The amorphous polysilicon layer may be deposited in a blanket deposition operation. An annealing operation is performed for the semiconductor device to remove voids, seams, and/or other defects from the amorphous polysilicon layer. The annealing operation may cause the amorphous polysilicon layer to crystallize, thereby resulting in the amorphous polysilicon layer transitioning into a crystallized polysilicon layer. A dual radio frequency (RF) source etch technique may be performed to increase the directionality of ions and radicals in a plasma that is used to etch the crystallized polysilicon layer to form the dummy gate structure. The increased directionality of the ions increases the effectiveness of the ions in etching through the different crystal grain boundaries which increases the etch rate uniformity across the crystallized polysilicon layer.

  • Publication number: 20230253253
    Abstract: A two-step etch technique is used in a continuous polysilicon on oxide definition edge (CPODE) recess process to form a recess in which the CPODE structure is to be formed. The two-step process includes performing a first etch operation using an isotropic etch technique, in which a recess in a dummy gate structure is formed to a first depth. A second etch operation is performed using anisotropic etch technique to form the recess to a second depth. The use of the anisotropic etch technique results in a highly directional (e.g., vertical) etch of the dummy gate structure in the second etch operation. The highly directional etch provided by the anisotropic etch technique at or near the bottom of the dummy gate structure reduces, minimizes, and/or prevents etching into adjacent portions of an interlayer dielectric (ILD) layer and/or into source/drain region(s) under the portions of the ILD layer.
