Referring to fig. 1 and 2, a substrate leveling device for double-sided digital exposure according to an embodiment of the present invention includes: fixing mechanism 200, suspension auxiliary support mechanism 300.
During exposure, the fixture 200 initially positions the substrate 100 to prevent movement of the substrate 100 relative to the fixture 200.
The auxiliary supporting mechanism 300 comprises an eddy current component 310 and a magnetic component 320, wherein when the eddy current component 310 is powered on during operation, a magnetic field is generated around the eddy current component 310 and interacts with the magnetic field generated by the magnetic component 320, so that an upward supporting force perpendicular to the surface of the substrate 100 is generated, and the flatness of the surface of the substrate 100 meets the exposure requirement.
In some embodiments of the present invention, the securing mechanism 200 includes a tensioning mechanism and/or a support mechanism. When the substrate 100 is sufficiently rigid and the central portion thereof sags to the extent allowed by exposure, it is no longer appropriate to apply tension, and only the support mechanism needs to be provided to fix the edge of the substrate 100. When the substrate 100 is not rigid enough and the sagging degree of the middle portion exceeds the allowable degree of exposure, a tensioning mechanism is required to apply a tensioning force parallel to the surface of the substrate 100 to the edge of the substrate 100 to control the sagging degree of the middle portion of the substrate 100. Of course, in some cases, both the tensioning mechanism and the support mechanism may be provided to support and tension the substrate 100 at different locations.
In some embodiments of the present invention, the substrate leveling device for double-sided digital exposure further includes a detection feedback mechanism for detecting the flatness of the surface of the substrate 100, and adjusting the supporting force according to the flatness, so that the flatness of the substrate 100 is within the allowable range of the exposure process. Specifically, a detection feedback mechanism may be formed by the flatness detector and the controller, and the controller adjusts the operating current of the eddy current assembly 310 according to the data fed back by the flatness detector, so as to achieve the purpose of changing the magnitude of the supporting force.

The eddy current coils 311 are symmetrically distributed along the center of the substrate 100 so that the magnetic field generated by them is uniformly distributed. The input contact 312 is electrically connected to the detection feedback mechanism, the detection feedback mechanism detects the flatness of the surface of the substrate 100, and when the flatness of the substrate 100 is not within the allowable range of the exposure process, the detection feedback mechanism adjusts the input current of the input contact 312, thereby achieving the purpose of adjusting the magnitude of the supporting force. As shown in fig. 2, the magnetic assembly 320 is disposed directly above and/or below the center of the substrate 100, so that the magnetic force acting on the substrate 100 is more uniform.
In some embodiments of the present invention, further, the eddy current coil 311 is formed by space projection imaging maskless lithography, so that it becomes a part of the substrate 100, and only needs to lead out the corresponding input contact 312 when in use. The mode can greatly improve the consistency of the electrical performance parameters, increase the electromagnetic coupling degree of the electromagnetic coupling device and reduce the distributed capacitance of the electromagnetic coupling device.
In some embodiments of the present invention, further, the eddy current coil 311 is manufactured and formed by FPC manufacturing process, and has the characteristics of light weight, thin thickness and good bending property, and can be directly attached to the surface of the substrate 100 by means of pasting.
