Abstract

The invention concerns a resistance-heated vaporizer boat for vaporizing metal. According to the invention, a reduced temperature is generated in the edge region, i.e., along the longitudinal edge of the vaporizer boat, such that there is only a very slight wetting tendency along this longitudinal edge. Consequently, the melt can be localized such that it cannot overflow over the longitudinal edges of the vaporizer boat, without a cavity necessarily having to be provided in the vaporization surface of the vaporizer boat. As a result, optimum wetting and constantly targeted vaporization of the metal upwards towards the area to be vapor-deposited are attained.
