Abstract:
Provided herein are approaches for forming a gate dielectric layer for a DRAM device, the method including providing a substrate having a recess formed therein, the recess including a sidewall surface and a bottom surface. The method may further include performing an ion implant into just the bottom surface of the recess, and forming a gate dielectric layer along the bottom surface of the recess and along the sidewall surface of the recess. Once formed, a thickness of the gate dielectric layer along the sidewall surface is approximately the same as a thickness of the gate dielectric layer along the bottom surface of the recess. In some embodiments, the gate dielectric layer is thermally grown within the recess. In some embodiments, the ion implant is performed after a mask layer atop the substrate is removed.

Claim (Index 17):
A method of forming a uniform gate oxide layer of a dynamic random-access memory device (DRAM) device, the method comprising:\n etching a plurality of buried channels in a substrate, each of the plurality of buried channels including a sidewall surface and a bottom surface; performing an ion implant into just the bottom surface of each of the plurality of buried channels; and forming a gate oxide layer along the bottom surface and along the sidewall surface of each of the plurality of buried channels after the ion implant is performed, wherein a thickness of the gate oxide layer along the sidewall surface is approximately the same as a thickness of the gate oxide layer along the bottom surface of each of the plurality of buried channels.
