A quick Google of "sublimation depostion" turns up:

I have always understood the distinction to be more of a colloquial
one, at least here in the US. 'Vapor' (sorry, no 'u' here) is
commonly used only when there is also liquid present. One may speak
of water vapor or the vapor pressure of a liquid, but would never
speak of hydrogen vapor, for example.
