A semiconductor process of the present invention is described as follows. A substrate is provided, and a material layer is deposited on the substrate using an organic precursor as a reactant gas. A plasma treatment is conducted immediately after depositing the material layer, wherein plasma is continuously supplied during depositing the material layer and the plasma treatment. A pump-down step is conducted.

Semiconductor process

A stress film forming method is used in a fabrication process of a semiconductor device. Firstly, a substrate is provided, wherein a first-polarity-channel MOSFET and a second-polarity-channel MOSFET are formed on the substrate. Then, at least one deposition-curing cycle process is performed to form a cured stress film over the first-polarity-channel MOSFET and the second-polarity-channel MOSFET. Afterwards, an additional deposition process is performed form a non-cured stress film on the cured stress film, wherein the cured stress film and the non-cured stress film are collectively formed as a seamless stress film.

Stress film forming method and stress film structure

A capacitance dielectric layer is provided. The capacitance dielectric layer includes a first dielectric layer, a second dielectric layer and a silicon nitride stacked layer. The silicon nitride stacked layer is disposed between the first dielectric layer and the second dielectric layer. The structure of the capacitance dielectric layer permits an increase in the capacitance per unit area by decreasing the thickness of the capacitance dielectric layer and eliminates the problems of having a raised leakage current and a diminished breakdown voltage.
