Metal Wiring Chemical and Resin Resist Stripping Solution for Electronic Manufacturing

TECHNOLOGY OVERVIEW

The manufacturing of electronic devices often involves multiple steps, where metal wiring is a fundamental component providing electrical connections and resin resist stripping solution is used to remove photoresist layers after the patterning and etching processes. Both steps are critical in the production of various electronic components, including printed circuit boards (PCBs), semiconductors, and microelectronic devices. Advances in such processes continue to push the boundaries of what's possible in electronics manufacturing, enabling the production of devices with higher performance, smaller size, and lower cost. Research and development efforts to seek safer, more efficient, and environmentally friendly methods are ongoing challenges.

The technology owner has developed a proprietary chemical solution for metal wiring, especially targeting copper (Cu) wiring, although metals such as aluminum and gold are also used due to their excellent electrical conductivity. This unique chemical solution can ensure high-quality and precious shape control of wiring formation. This is also complemented by an advanced resin resist stripping solution, which not only exfoliates the photoresist, but also preserves the base metal from scraping / damage. On top of this, this solution enables controlled roughing of metal surfaces to meet specific requirements. The effectiveness of both solutions has been validated in the mass production of liquid crystal panels.

The technology owner is seeking R&D collaboration with industrial partners interested in adopting these solutions into their electronic device manufacturing lines.
