Subsequently, while injecting a raw material gas from raw material gas injection orifices toward the supporting electrodes and also injecting a barrier gas from barrier gas injection orifices in the same direction as the direction in which the raw material gas is injected, the gases are discharged from a gas outlet, and thereby, the pressure in a chamber is controlled to a pressure of more than 1 kPa. Then, a DC pulse voltage is applied to each counter electrode to deposit a silicon-based thin film. A DC pulse voltage is applied to perform discharge. Therefore, even in a state where the distance between the electrodes is increased, plasma can be generated efficiently, and the in-plane distribution of film thickness can be improved. | 10-01-2009 |

Unlike methods in which a radio frequency voltage is intermittently applied to perform discharge, a high plasma density distribution does not occur, and in-plane film thickness distribution does not occur. Furthermore, since the DC pulse voltage rises sharply, the ON period can be shortened. As a result, generation of a sheath ceases in the transient state before reaching the steady state, and the thickness of the sheath is small, which allows the space between the counter and transparent electrodes to decrease. | 10-01-2009 |
