    Abstract: A hole which is to be a part of an interconnection (wiring) hole (21) is formed penetrating through a second insulating layer (13) and a third insulating layer (14) made of porous silicon oxide film, by etching. Further, a second groove (23) is formed on the third insulating layer (14) using a second stopper film (20), by etching. Further, direct nitriding of a silicon oxide film applying an RLSA plasma processing deice is carried out on the side wall of the interconnection hole (21) and the second groove (23), and a barrier layer (25) made of SiN film is formed. Here, the second stopper film (20) and the bazrier layer (25) are formed by the same direct nitriding.

    Abstract: 본 발명에 있어서는, 산화막 형성 후의 기판에 대해서, 마이크로파에 의해서 발생시킨 플라즈마에 의해 질화 처리하여 산질화막을 형성할 때, 마이크로파의 공급을 단속적으로 행한다. 단속적으로 마이크로파를 공급함으로써, 전자 온도의 저하에 따른 이온 충격이 저하하고, 또한 산화막에 있어서의 질화물 시드의 확산 속도가 저하하며, 그 결과 산질화막의 기판측 계면에 질소가 집중하여 그 농도가 높게 되는 것을 억제할 수 있다. 이에 따라, 산질화막의 막질을 향상시켜 리크 전류의 저하, 동작 속도의 향상, 및 NBTI 내성의 향상을 도모하는 것이 가능하다.
