Abstract:
A semiconductor memory device includes a semiconductor substrate, a first support layer, a first electrode, a capacitor dielectric layer, and a second electrode. The first support layer is disposed on the semiconductor substrate. The first electrode is disposed on the semiconductor substrate and penetrates the first support layer. The capacitor dielectric layer is disposed on the first electrode. The second electrode is disposed on the semiconductor substrate, and at least a part of the capacitor dielectric layer is disposed between the first electrode and the second electrode. The first support layer includes a carbon doped nitride layer, and a carbon concentration of a bottom portion of the first support layer is higher than a carbon concentration of a top portion of the first support layer.

Claim (Index 12):
A manufacturing method of a semiconductor memory device, comprising:\n providing a semiconductor substrate; forming a first oxide layer and a first support layer on the semiconductor substrate sequentially; performing a first etching process for patterning the first oxide layer and the first support layer; forming a first electrode on the semiconductor substrate after the first etching process, wherein the first electrode penetrates the first support layer and the first oxide layer; and performing a second etching process for removing the first oxide layer after the step of forming the first electrode, wherein an etching rate of a bottom portion of the first support layer in the second etching process is lower than an etching rate of a top portion of the first support layer in the second etching process.
