Abstract:
1. An apparatus for forming deposited film comprising a chamber, a first electrode positioned in the chamber and a second electrode positioned apart from the first electrode at a predetermined distance in the chamber, wherein the second electrode comprises an electrode substrate and a plurality of electrode plates disposed on the electrode substrate, wherein each of the electrode plates comprises a first supply part for supplying a first material gas to a space between the first electrode and the second electrode, a second supply part for supplying a second material gas to the space, a first supply path which is connected to the first supply part and into which the first material gas is to be introduced, and a second supply path which is connected to the second supply part and into which the second material gas is to be introduced, wherein the electrode substrate comprises a heater for heating the first material gas, a first introducing path for introducing the first material gas to the first supply path, and a second introducing path for introducing the second material gas to the second supply path, wherein the second supply path comprises a main stream part into which the second material gas is to be introduced from the second introducing path and which is not provided with the second supply part, and a plurality of branch parts into which the second material gas is to be introduced from the main stream part and which is provided with the second supply part, and wherein, for each electrode plate, the second introducing path connects to the main stream part at at least one edge portion of the electrode plate.
