Description

Technical Field

[0001] The utility model belongs to the technical field of electronic device production equipment, in particular to a transient electronic device transfer device. Background Art

[0002] Transient electronic devices refer to an emerging type of electronic device whose physical form and function can disappear partially or completely immediately under external stimuli after completing the specified function. The basic components of transient electronic devices mainly include substrate materials, inorganic semiconductor materials and interconnecting wires. In the prior art, the preparation methods that have been proven to be feasible include transfer printing, optical pulse sintering and laser evaporation.

[0003] The most general form of the transfer method is to use a soft elastomeric stamp to mediate the physical mass transfer of microdevices between a donor substrate and a secondary receiving substrate. It generally includes two steps: retrieval / ink pickup from a donor substrate and printing / delivery of the ink to a receiving substrate. At the beginning of the retrieval process, the stamp is brought into contact with the donor substrate, on which the ink is usually prepared by wet chemical etching or dry etching (e.g., laser lift-off) in an orderly and releasable manner. For example, wet chemical etching produces a releasable ink by etching a sacrificial layer between the ink and the substrate, but with a properly defined anchor structure to maintain the spatial layout of the elements defined by lithography. An appropriate preload is applied to the stamp to ensure conformal contact between the stamp and the ink, which provides sufficient adhesion to retrieve the ink from the donor substrate. The retrieval process can be non-selective in a massively parallel manner for high throughput or selective for precise manipulation of a single ink or several inks. The inked stamp is then brought into contact with the receiving substrate, and the stamp / ink adhesion is then modulated to print the printed ink onto the receiving substrate. At present, ordinary transfer equipment needs to adjust the substrate surface state separately before transfer, which affects both the processing efficiency and transfer speed. In this case, if a transfer equipment with substrate surface state adjustment function can be designed, it is expected to further improve the transfer efficiency. Summary of the invention
