titleOfInvention |
Method for manufacturing electronic device by forming a hole in a multilayer insulator film by plasma etching |
abstract |
A method includes the stage of partially removing a first insulator layer to form an opening passing through the first insulator layer by plasma etching using a gas of a first type, and the stage of partially removing a second insulator layer to form an opening passing through the second insulator layer by plasma etching using a gas of a second type. The gas of a first type contains a first component capable of etching the first insulator layer, and a gas of the second type contains a second component different from the first component, capable of etching the second insulator layer and a third component having a higher deposition ability than the second component. |
