He said other things as well, but they’re called structuralism rather than semiotics, I think.
According to Wikipedia Structuralism is a subtopic of Semiotics.
However, so far I don’t see that Saussure added anything to the notion of intensional representation developed by Frege, Church, and Carnap by 1947, and he had none of their logical rigor.
It seems like Saussure died in 1913. As such he couldn’t really add something to Frege/Church/Carnap but rather presed them.
Sorry, what I meant was that there isn’t much to gain from his thoughts on the matter, because someone else did it more thoroughly, later, independently. Though Saussure’s formulation is much simpler and easier to understand.

I think the same is true for most people who died more than 100 years ago.
