Method of manufacturing optoelectronic components and device for manufacturing optoelectronic components

A device that manufactures an optoelectronic component comprising:

• equipment that generates an electric potential difference;
• a substrate holder that holds a substrate;
• and
• equipment that sprays an electrically charged substance or an at least partially electrically charged substance mixture through a nozzle under pressure to form a jet of the electrically charged substance or the at least partially electrically charged substance mixture, configured to adjust the thickness of the sprayed-on electrically charged substance or the sprayed-on at least partially electrically charged substance mixture by various electrical changes of potential on the substrate;
• measures a local layer thickness of the applied fluorescent layer;
• and
• locally adjusts an amount of the electrically charged substance or the at least partially electrically charged substance mixture by a ray optics based on the measured layer thickness information, wherein the ray optics can shape or direct the jet of the substance or substance mixture,
• wherein the equipment that generates an electric potential difference comprises a voltage source that generates the electric potential difference which is configured between a first electrode and a second electrode electrically connected to the voltage source and one electrical potential value of the electric potential difference is of the electrically charged substance or the at least partially electrically charged substance mixture and another electrical potential value of the electric potential difference is of the substrate, and
• the equipment that generates an electric potential difference generates the electric potential difference configured by the electrically charged sprayed-on substance or the at least partially electrically charged sprayed-on substance mixture and an earthed substrate, and the electric potential difference is configured by electrostatically charging the substrate holder and/or the electrically charged sprayed-on substance or at least partially electrically charged sprayed-on substance mixture on the substrate.
