Abstract

The disclosure relates to a method for preparing and testing a multilayer flexible electronic thin film device, comprising: depositing a first metal layer on a substrate layer; performing first photolithography and etching on the first metal layer to obtain a first electrode; Coating a photosensitive layer on the first electrode; performing photolithography and etching treatment on the photosensitive layer to open a first connection hole in the photosensitive layer to form a photosensitive layer after the hole is opened; depositing the second photosensitive layer on the photosensitive layer after the hole is opened Two metal layers; second photolithography and etching treatment are performed on the second metal layer to obtain the first strain sensor and the second electrode; wherein, the second electrode is facing the first electrode, the second electrode, the first electrode and the second electrode The photosensitive layer between the electrode and the first electrode forms a pressure sensor; the first electrode is electrically connected to the first strain sensor through the first wiring hole; the substrate layer, the first strain sensor, the photosensitive layer, the first electrode, and the second electrode Made of flexible material. The embodiments of the present disclosure can realize the integration of sensing and signal processing.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductors, in particular to a method for preparing and testing a multilayer flexible electronic thin film device. Background technique [0002] Flexible electronic devices are the same as traditional electronic circuit devices based on hard printed circuit boards, with sensor parts, signal processing parts, etc. The original signal collected by the sensor designed and prepared based on flexible electronic technology is generally an analog signal. Before the analog signal is transmitted, the analog signal needs to be filtered and amplified by the signal processing part. In related technologies, the flexible electronic sensor only has a signal sensor part and cannot directly process analog signals, and an additional signal processing part is required to realize signal processing. Contents of the invention [0003] In view of this, the present disclosure proposes a method for preparing and t...
