Patent ID: 8012260

Claim:
An apparatus for coating an areal substrate, comprising: a coating chamber; a stationary vaporizer source to produce a vapor by vaporizing materials with which the substrate is to be coated; a drive which linearly moves the areal substrate relative to the vaporizer source; a first distributor vertically disposed in the coating chamber which linearly distributes the vapor by the vaporizer source on said substrate, whereby the direction of vapor emission of said first distributor is substantially normal to the surface of the areal substrate and wherein linear distribution of the vapor takes place through several holes disposed in a substantially vertical straight line; a second distributor having one end disposed at least in the proximity of the vaporizer source and another end that terminates in the first distributor; wherein the first distributor and the second distributor are each encompassed by a sleeve, wherein the sleeves are provided with electric heating elements.
