  • Publication number: 20230145250
    Abstract: The application relates to a substrate structure, an on-chip structure, and a method for manufacturing the on-chip structure. The substrate structure includes a substrate body and an electrothermal layer. The electrothermal layer is arranged on a surface of the substrate body for growing an epitaxial layer. In an actual lift off process of the epitaxial layer, only the electrothermal layer is electrically conducted to an external power supply via an electrode, and heating of the electrothermal layer is utilized to heat the epitaxial layer, therefore, a part of the epitaxial layer in contact with the substrate structure can be thermally decomposed and separated from the substrate structure.

  • Publication number: 20220045252
    Abstract: The disclosure herein relates to a bonding device and a bonding method used in a microcomponent process, and a welding-agent placing unit. The method includes the following. A microcomponent to-be-bonded is peeled from a substrate, picked up and transferred, by a transfer unit, the microcomponent to-be-bonded to a welding-agent placing unit so as to make the electrode to-be-bonded adhere to the molten welding agent from a welding-agent hole in the welding-agent placing unit. The microcomponent to-be-bonded with molten welding agent is transferred to a driving backplate so as to realize the bonding process between the microcomponent to-be-bonded and the driving backplate after cooling of welding agent.
