| Zusammenfassung: | Provided are a semiconductor device in which the occurrence of a short circuit between a gate electrode and either of the source/drain regions of a transistor can be suppressed and a manufacturing method thereof. In the semiconductor device, a first insulating layer formed over the gate electrode and containing a silicon nitride has an upper surface having a depressed portion which is formed in a region over a second electrode layer of the gate electrode containing a silicide. |
