Description

technical field [0001] The invention belongs to the technical field of electronic / optoelectronic manufacturing, and specifically relates to a special equipment for laser micro cladding. Fabrication of waveguides. Background technique [0002] The emergence and development of large-scale integrated circuits has led to the continuous development of electronic manufacturing technology in the direction of integration, miniaturization, short timeliness, small batches, multi-variety and three-dimensional manufacturing. Layer wiring, the factor that restricts the further improvement of the quality of electronic products has changed from the original chip size to the interconnection line spacing between chips. [0003] In 2000, the inventor proposed the technology of laser micro cladding electronic paste to prepare wires, that is, laser micro cladding flexible direct writing technology, and developed the manufacturing system and equipment based on this technology. This technology ...

AI Technical Summary

Problems solved by technology

However, there are several problems in using the rotary coating method to preset the film layer: first, the thickness of the preset film is not uniform; second, the excess slurry needs to be removed after laser direct writing, and the cleaned slurry cannot be recycled. Material waste is serious; third, this method cannot preset different materials on the same substrate

However, the existing working platform cannot meet the requirements of the composite process, and the distribution of tools is scattered. When multiple materials are preset on the same substrate, the direct writing device needs to be replaced and cleaned frequently, and the relative position and adjustment of the processing tool and the substrate must be relocated. Therefore, in actual processing, there are many repetitive tasks and complicated operation steps, and it is impossible to maximize the advantages of micro-pen, micro-spray and laser composite, and it is difficult to meet the requirements of industrial rapid composite manufacturing. It is only suitable for laboratories. research work or small batch production
