Problems solved by technology

Such a process introduces new process steps, increases device cost, and is inefficient
In addition, the upper device is immersed in the corrosive solution, which will easily lead to device failure, performance degradation, and yield reduction
[0005] Although the laser lift-off process is highly efficient, the laser equipment is expensive and has a limited lifespan. Moreover, the process can only be applied to specific opaque flexible PI substrates, and the scope of use is very limited.

Abstract

The invention provides a method for separating a flexible substrate and a rigid conductive carrier; the method comprises the following steps that the first end of the rigid conductive carrier is in contact with a conductive solution, wherein the flexible substrate is formed on the rigid conductive carrier; and a voltage is applied to the second end of the rigid conductive carrier and the conductive solution so as to separate the rigid conductive carrier from the flexible substrate, wherein the conductive solution is capable of corroding the surface, facing the flexible substrate, of the rigidconductive carrier.

Description

technical field [0001] The present disclosure relates to flexible substrates, and in particular to a method of separating a flexible substrate from a rigid conductive carrier. Background technique [0002] Flexible electronic devices are electronic or optoelectronic devices that can be bent, folded, or stretched on flexible substrates such as plastics. Flexible electronic devices have shown great application potential in the fields of flexible display, electronic skin, sensing, solar cells, and energy storage. Flexible electronic devices must not only meet high performance standards, but also be able to achieve a more friendly interaction with the human body. This requires that the thickness of flexible electronic devices be reduced to realize thin and light flexible thin film devices. For example, for flexible electronic skin devices to be combined with human skin and other tissues and organs, the overall thickness of the device needs to be greatly reduced to achieve conf...
