Abstract

A semiconductor component includes a substrate having an opening. The semiconductor component further includes a first dielectric liner in the opening, wherein the first dielectric liner having a thickness Tat a first end of the opening, and a thickness Tat a second end of the opening, and Ris a ratio of Tto T. The semiconductor component further includes a second dielectric liner over the first dielectric liner, wherein the second dielectric liner having a thickness Tat the first end of the opening, a thickness Tat the second end of the opening, Ris a ratio of Tto T, and Ris greater than R.
