Abstract:
A fabricating method of a stop layer includes providing a substrate. The substrate is divided into a memory region and a peripheral circuit region. Two conductive lines are disposed within the peripheral circuit region. Then, an atomic layer deposition is performed to form a silicon nitride layer to cover the conductive lines. Later, after forming the silicon nitride layer, a silicon carbon nitride layer is formed to cover the silicon nitride layer. The silicon carbon nitride layer serves as a stop layer.

Claim (Index 1):
A semiconductor structure comprising conductive lines, comprising:\n a substrate which is divided into a memory region and a peripheral region; a first conductive line disposed in the peripheral region; a silicon nitride layer covering the first conductive line; a silicon carbon nitride layer covering and in direct contact with the silicon nitride layer; and a second conductive line disposed in the peripheral region and parallel with the first conductive line, two first spacers respectively disposed on two sides of the first conductive line, and two second spacers respectively disposed on two sides of the second conductive line, wherein one of the two first spacers and one of the two second spacers are adjacent to each other and spaced apart from each other by a space ranging from 130 nm to 170 nm.
