Problems solved by technology

[0010] This approach, although reducing the risk of simulation failure, moves the overhead from the calculation side to the measurement side, so that the associated overhead still results in high costs
Due to the complex calculations, an automated adjustment of the coating system cannot be carried out easily either, since the results of the compensation calculations cannot be assured
Therefore, quality assurance can only be implemented with extensive knowledge and long-term experience and must be continuously manually recalibrated and / or verified

Abstract

The invention relates to a method, a non-volatile memory and a control device. According to different embodiments, the method (100) for coating comprises: forming (101) a first layer stack on a firstsubstrate (112) by means of a multiplicity of coating processes, each coating process of which forms at least one layer of the first layer stack; detecting (103) an optical spectrum of the first layerstack; determining (105) correction information for at least one coating process of the multiplicity of coating processes using a model, wherein the model provides a right-unique mapping function between a deviation of the spectrum from a desired spectrum and the correction information; and changing (107) at least one control parameter for controlling the at least one coating process of the multiplicity of coating processes using the correction information; and forming (109) a second layer stack on the first or a second substrate (112) by means of the multiplicity of coating processes using the changed control parameter, each coating process of which forms at least one layer of the second layer stack.

Description

technical field [0001] The invention relates to a method, a non-volatile memory and a control device. Background technique [0002] In general, the optical properties of transparent supports such as glass disks, films etc. can be changed by means of coating. Traditionally, for example, window panes are equipped with coatings which reflect infrared light as much as possible and at the same time have a certain aesthetic or optical transparency. The balance between the transparency and the reflective properties of eg coated glass panes results in complex parameter dependencies, especially when layer systems are used which have a plurality of layers arranged one above the other. In addition to the optical material properties, the angular dependence of the optical properties and the scattering relationship can also be taken into account. Therefore, various layer systems have been developed which are adapted to the specific purpose of use. [0003] Rising demands for cost reduc...
