摘要

#CMT# #/CMT# The method for coating a substrate with a conductive and transparent metallic oxide layer by sputtering in a continuous process, comprises moving and coating the substrate in a coating chamber at a coating source with a tubular target of the metallic oxide. The substrate has a temperature range from room temperature to 90[deg] C during the coating process, and the applied layer is subsequently heat treated. The thermal treatment is made via the separation of a further layer by the conductive layer after breaking of the vacuum in a separate process. #CMT# : #/CMT# The method for coating a substrate with a conductive and transparent metallic oxide layer by sputtering in a continuous process, comprises moving and coating the substrate in a coating chamber at a coating source with a tubular target of the metallic oxide. The substrate has a temperature range from room temperature to 90[deg] C during the coating process, and the applied layer is subsequently heat treated. The thermal treatment is made via the separation of a further layer by the conductive layer after breaking of the vacuum in a separate process. The thermal treatment of the metal oxide layer takes place at >= 350[deg] C. The substrate temperature is varied from ambient temperature to 90[deg] C by cleaning before the coating process. #CMT#USE : #/CMT# Method for coating a substrate with a conductive and transparent metallic oxide layer by sputtering in a continuous process, where the substrate is useful as e.g. transparent electrodes in thin film solar cells or in flat screens or components in optically selective layer systems. #CMT#ADVANTAGE : #/CMT# The method is capable of economically coating a substrate with improved and homogeneous optical and electrical characteristics of the layer such as transmission and specific surface resistance.
