Abstract:
According to an exemplary embodiment, a method of forming an isolation layer is provided. The method includes the following operations: providing a substrate; providing a vertical structure having a first layer over the substrate; providing a first interlayer dielectric over the first layer; performing CMP on the first interlayer dielectric; and etching back the first interlayer dielectric and the first layer to form the isolation layer corresponding to a source of the vertical structure.

Claim (Index 4):
The method of  claim 1 , wherein the isolation layer is formed by:\n forming an etch stop layer over the vertical structure, the etch stop layer including:\n a horizontal upper portion overlying a top of the vertical structure, and \n a vertical side portion extending downward from the upper portion and in overlying contact with a side of the source, channel and drain regions; \n providing a second ILD layer over the etch stop layer's upper and side portions; performing CMP on the second ILD layer, and stopping the CMP upon reaching a top of the etch stop layer's upper portion; and etching back the second ILD layer and the etch stop layer's side portion, thereby exposing the side of the channel and the drain and forming the isolation layer.
