Abstract

The invention relates to a transfer printing method and device of a flexible semiconductor film and a liquid drop seal. The method comprises the steps of forming a first liquid drop on a seal bearing body, and obtaining the liquid drop seal; controlling the liquid drop seal to be close to the flexible semiconductor film so as to form a first liquid bridge between the flexible semiconductor film and the seal bearing body by using the first liquid drop; moving the liquid drop seal, and adsorbing the flexible semiconductor film to the liquid drop seal through the first liquid bridge; forming a second liquid drop on a flexible substrate; controlling the liquid drop seal to be close to the second liquid drop so as to form a second liquid bridge between the flexible substrate and the flexible semiconductor film by using the second liquid drop; and moving the liquid drop seal, adsorbing the flexible semiconductor thin film to the flexible substrate through the second liquid bridge, and separating the flexible semiconductor thin film from the liquid drop seal to complete transfer printing of the flexible semiconductor thin film. According to the method, the semiconductor thin film can be prevented from being damaged in the transfer printing process, and a hybrid integrated flexible device can be efficiently prepared.

Description

technical field [0001] The present disclosure relates to the field of flexible electronics, in particular to a transfer printing method and device for a flexible semiconductor film, and a droplet stamp. Background technique [0002] As a new type of semiconductor device, flexible electronic devices have made great breakthroughs in clinical monitoring and other applications. Flexible electronic devices can be made using different functional materials. For example, gallium nitride GaN or gallium arsenide GaAs are usually used to manufacture light-emitting elements. In order to integrate light-emitting elements on soft substrates to prepare flexible photodetectors, the light-emitting elements are It is an effective technical solution to form a flexible semiconductor film with light-emitting function, and then transfer the flexible semiconductor film to a silicon wafer. [0003] However, in the related art, in the process of transferring the flexible semiconductor film to the s...
