Patent ID: 8440020

Claim:
An apparatus for the continuous production of flexible semi-conductor devices through deposition of a plurality of semiconductor layers onto a moving flexible substrate by using Plasma Chemical Vapor Deposition processing, said apparatus comprising: at least one deposition chamber, said at least one deposition chamber including at least one reaction region for plasma generation; a plurality of valves each for introducing a corresponding different one of a plurality gasses into the deposition chamber; a controller adapted for controlling said plurality of valves for the alternative introduction of said corresponding different gases into the reaction region, wherein each one said gases is for depositing a different semiconductor layer on said substrate; a RF power generator for the generation of electromagnetic power needed for plasma generation; a vacuum pump; two rotatable rolls, arranged so that said flexible substrate can be unrolled from one roll and rolled onto the other roll; at least one motor for rotating said two rolls, wherein said at least one motor is arranged so that the sense of rotation of said two rolls can be changed; and friction elements for tensioning the substrate while said substrate is being unrolled from one said roll and rolled onto the other said roll.
