Abstract

The invention provides a flexible electronic device and a manufacturing method therefor. The electronic device comprises a flexible substrate and a device layer formed on the flexible substrate. The device comprises a semiconductor structure and a wire structure, which are connected with each other. The extending direction of the wire structure is consistent with the trench direction of the semiconductor structure. The extending direction of a first wire structure and the stretching direction of the flexible substrate form an inclined angle which is less than 90 degrees. According to the invention, the impact on the semiconductor structure and the first wire structure from stress is reduced to the minimum value through the adjustment of the trench direction of the semiconductor structure and the extending direction of the first wire structure, thereby guaranteeing the electrical performances and anti-kneading performances of the flexible electronic device.

Description
