Abstract:
1. A method for manufacturing flat substrates with an extent of at least of 2500 cm 2 and having a Si layer, deposited by means of a PECVD process in a vacuum reactor with a substrate carrier first electrode and spaced therefrom, a gas shower second electrode comprising: a) generating an RF plasma discharge in a reaction space between said electrodes; b) depositing on at least a part of the inner surface of said reactor a dielectric precoat; c) introducing one substrate into said reactor; d) depositing on a surface of said substrate a dielectric layer; e) PECVD depositing on said dielectric layer said Si-layer; f) repeating steps b) to e)for each single substrate to be manufactured, thereby depositing said silicon layer as a microcrystalline silicon layer and to do so selecting said dielectric layer deposited on said surface of said substrate as well as said precoating to allow said silicon layer to grow up as a microcrystalline silicon layer along said substrate.
