Abstract

Die Erfindung betrifft eine Schreibeinrichtung zum gesteuerten Aufbringen von Ladungsträgern auf ein Substrat, wobei eine Ladungsträgerquelle zur Erzeugung der Ladungsträger an einen ersten Pol und an einen zweiten Pol einer Spannungsquelle angeschlossen ist, wodurch ein Stromkreis ausgebildet wird, in dem sich eine Steuereinrichtung befindet, und mit einem dritten Pol der Spannungsquelle, der ein vorbestimmbares elektrisches Potential auf dem Substrat erzeugt, so daß dort durch entsprechendes Ansteuern der Steuereinrichtung die Ladungsträger aufbringbar sind. Es ist vorgesehen, daß die Steuereinrichtung (17) dem ersten oder dem zweiten Pol (5, 6) zugeordnet ist und sich etwa auf O-Volt-Potential befindet.

The invention relates to a writing device for the controlled application of charge carriers to a substrate, a charge carrier source for generating the charge carriers being connected to a first pole and to a second pole of a voltage source, as a result of which a circuit is formed in which a control device is located and with a third pole of the voltage source, which generates a predeterminable electrical potential on the substrate, so that the charge carriers can be applied there by correspondingly controlling the control device. It is provided that the control device (17) is assigned to the first or the second pole (5, 6) and is approximately at 0 volt potential.
