Abstract
In a method and a device for generating vapor for a CVD or PVD device, liquid or solid particles of a first source material are fed into a first heat transfer body via a first feed line. The first heat transfer body vaporizes the particles into a first vapor, which is transported by a carrier gas from the first heat transfer body into a second heat transfer body arranged after the first heat transfer body. The first heat transfer body is heated to a first temperature, and the second heat transfer body is heated to a second temperature. Liquid or solid particles of a second source material are fed into a second heat transfer body via a second feed line. The second heat transfer body vaporizes the particles into a second vapor, which is transported along with the first vapor out of the second heat transfer body by the carrier gas.
