Well, surely you meant "silicon-on-sapphire", right?
Searching on google for it returns a lot of information.

However, as eagerly SMP pointed out, silicone on sapphire may have a different meaning

I believe that HP did not invented SOS technology.
According to this paper, that honor belongs to North American Aviation in 1963.

For example, this HP journal from 1978 refers the First HP Product to Use Silicon-on-Sapphire Technology. Also this one here.
